This department handles all the plant work for production. This
department is responsible for all tech production and its process
going at assembly l ine and also the PDI (Pre Delivery Inspection).
They deal with all the workers to get the work output from them for
production. They decide which model is to be assembled according
to the availabil i ty of material and demand of production.
3. QUALITY CONTROL DEPARTMENT
Aiming the target of zero defects in their product this department
has to play a very challenging role. Attainment of prestigious quality
certif icate such as QS 9000 as Ashok Leyland has the landmark of
being the first auto industry in India to receive this honour. So to
keep the real value responsibil i ty of this department becomes
tougher. So personnel of this department has to keep a sharp eye on
every activity so that a minute kind of defect must not be allowed
with their product.
The QC department of Ashok Leyland, Alwar is running under wise
guidance of Mr. Vinay Bhargava along with cooperation of Mr.
Rajendra Yadav & Vinay Gupta.
Currently nine personnel are deployed under this department and
QC department work is distributed among three sections: f irst one is
GR&D, LINE and the last one is PDI.
This department is responsible for the quality of products and parts
whatever they sell or purchase. The quality checking is done in
three processes which are given as follows:
Incoming material inspection
In-process inspection
Final inspection
There is a GR & D (Goods receipt and dispatch) section which
receives good and QC department inspect them and ensure the
quality as per the recommended standards and then send them to
store.
For in-process inspection they use one chassis-card in which the
worker check whether all things has been done which he had to do
and then do signature in the card. This is known as self-certif ication.
When the chassis become off-track to the assembly l ine then the
chassis goes for a road-test. The defects and shortcoming in the
chassis are noted such as noise, smoke, driving control etc. Then an
inspection of chassis takes place at PDI and then all the defects are
noted and are rectif ied. After that the chassis is passed to sales
department by QC department.
PDI (PRE DELIVERY INSPECTION):-
It under comes the quality department but it has much uti l i ty that it
has an important role in the production.
The vehicle coming from assembly l ine is not perfect in quality. It
has many defects. So the chassis is inspected, faults are arrested in
this section and all the defects and faults are noted. The chassis
comes into PDI section after road-testing.
Then all the defects and faults found in the chassis are rectif ied
using necessary tools and items. Then the chassis is painted in the
paint booth and if there is any dent on the chassis FES, then it is
removed and finally passed to sales department. The chassis
passed from PDI is fault free and perfect in quality.
Painting of the chassis is also done under this department.
GR&D (Goods Receive and Dispatch)
This department is provided or giving their services when the goods
are received in the plant as a material from outside and when it
dispatch outside the plant.
This basically gives their service for quality and amount assuring.
UNIT PLANNING DEPARTMENT:-
This department basically does the planning work. They are given
the project of some new units to be prepared in the plant for which
they plan the appropriate place installation of the new unit the
approximate duration of completion of project cost estimation and
benefits of the installation of new unit.
Presently they are taking care of new rear axle assembly conveyor
l ine project being installed in shop-2 paint booth for body painting of
futon bus in shop-5.
PURCHASE DEPARTMENT:-
Raw material is very important for the production. All the raw
material is purchased by purchase department from various dealers
and companies. They decide which material should from which
company.
They also look at the cost of material to be purchased and the
transportation charges. It is better if the material is coming from a
place near to the plant because the transportation cost wil l be
reduced.
They also decided the firm to sell the scrap items of iron, wood etc.
The tender wil l be given to whoever wil l pay more.
They also hire the contractors from the market by tendering to
manage much work in plants l ike material unloading, transportation
construction.
FINANCE DEPARTMENT:-
This department takes care of al l f inancial things of the plant. It
keeps record of al l the salaries and all al lowances of the employees,
the money spent on purchasing the things for the plant, the money
earned by the sale of products and other f inancial activit ies. It
prepares a monthly and annual budget of the plant.
It also monitors the attendance of the employees by an electronic
card punching attendance system. All the employees are provided
with an electronic card which is punched in the card punching
machine at the t ime of entering the plant and at the t ime of leaving
the plan. The time of punching wil l be noted by the machine and
thus the department gets the data.
SALES AND MARKETING DEPARTMENT:-
Products are made in the plant and they need to be sold to the
customers. This department takes care of al l the marketing
activit ies. After the product is passed from QC department, sales
and marketing activit ies. After the product is passed from QC
department, sales and marketing department keeps all the products
at R.S.O. (Regional Sales Office). With safety the vehicle is kept in
the R.S.O. after f i t t ing the heat guards, warning triangles, RUPD
(Rear Under Protection Device) and Canopy as per the government
rule. Then at demand and requirement the products are sent to the
dealers.
They look at the demand of product in the market and the
customer’s feedback about the product. They also provide the
training for servicing of the product.
They send their report that in what amount has demand to
production department so that they can decide the amount of
production that they can.
PPC DEPARTMENT:-
Production planning and control department is known as PPC
department. This department control GR & D section and store-
rooms. They receive the goods coming from the factories. Then
according to the vouchers, counting of parts is done. They prepare a
daily report of goods received and send it to Finance department for
further procedure.
They allot part number for the parts and parts arranged according to
the part number in the store-room. They keep all the records of
store-room. Monthly counting of parts is also done.
CONCLUSIONS
The bird eye view of my project is that in this competit ive market
human resources are the major assets of an organization. Therefore,
ASHOK LEYLAND Alwar, India really focuses to f ind out the
effective sources of recruitment & selection process. The researcher
has done enough research on sources of recruitment & selection
process of the company. The researcher has come up with certain
recommendations that are to be adopted, which on implementation
would be beneficial for the company in long run. There are certain
inferences what was found through the project in the company and
are given below-
ASHOK LEYLAND Alwar is using both sources of recruitment i.e.
internal and external sources.
ASHOK LEYLAND Alwar, India prefers to use placement
agencies as a method of external sources of recruitment.
Company also recruits candidates through employee reference as
an internal source.
ASHOK LEYLAND Alwar, India recruits the temporary
employees on daily and weekly basis as well as
occasionally because when company feels shortage of manpower
in the lower level management, at that junction it recruits the
candidates on daily basis where as shortage of manpower in
middle level management at that point of t ime recruitment
and selection is done but this situation comes occasionally.
Theoretically, there are eight standard steps of selection process
but company follows one to f ive steps for selecting the
candidates, for example temporary employees are selected with
in one to two steps where as permanent employees and
executive are selected with in three to f ive steps.
After selection of the candidates they are on a probation period
of six months and after six months if their performance matches
with the job description, they are appointed on the payroll of the
company.
There are some internal and external factors which affect the
recruitment and selection process and the factors which affect
most are place of posting and compensation structure.
Apprentice is recruited from the organization whose temporary
employees completed 6 month period.
LIMITATIONS OF THE STUDY
This project is l imited to one plant of Ashok Leyland Alwar, which
is based in Alwar (Rajasthan).
Some data was confidential and not disclosed as per the
company’s policy.
Time l imitation was the major factor for the study.
RECOMMENDATIONS
On the basis of the research work there are several points, which
came as a conclusion and according to that there are some points
which are pointed out as recommendations, and if company follows
these points then company can effectively recruit and select the
candidates and increase the retention of the employees. These
points are given as follows:-
1. The Company at present is mostly uti l izing the source of
recruitment by employee referrals and placement agencies. If the
company goes for other effective sources of recruitment l ike job
portals and advertisements, i t can get some effective and
eff icient candidates for recruitment and selection.
2. Company should decrease the complexity of the selection
procedure for lower level employees while hiring the candidates
for judging their competencies.
3. For selecting the candidates, company should go for some new
technical and creative tests as a compulsory test apart from the
aptitude and trade test for the employees.
4. At present the probation period in ASHOK LEYLAND, ALWAR is
up to six months. It is advisable for the company that people at
the different post should be given different probation period.

PROJECT
TITLE:Study of the production of goods Trucks and Buses.
INTRODUCTION:The project is related to the improvement of the production rate of the Goods Truck & Buses. Since truck & Buses assembly is recently started in Alwar plant of ASHOK LEYLAND LTD, therefore some improvement for reducing assembly time &increase in productivity & also making easier assembly process inevitable. It includes suggestion & taking them under consideration for new layout & new manufacturing system.
INTRODUCTION TO PRODUCTION (Trucks & Buses):
Assembly stages are given below:● Framing● Lay Down● Bracketing Stages● Piping Stages● Engine Mounting 1● Engine Mounting 2● Lubrication● Off track 1●Off track 2● Road Testing● Pre Delivery Inspection(PDI)
FRAMING
This is the first stage of the whole assembly line. As the name suggesting at this stage frame of chassis is given the shape in form of ladder. This ladder shape form is given with help of two side members and several cross members. Number of cross member varies from model to model.All cross members along with brackets, which hold and support other components that will assemble later on are made connected to side member, which comes previously drilled form. So all cross member along with brackets made fixed at their respective position with help of bolts and nuts. Flitchs are also inserted to side member which provides extra strength to frame.General brackets which assembled to frame are to support radiator, engine bracket, spring brackets. The size and structure of each bracket varies from model to model.Material for all frames is mild steel and length of cross member remains constant that is about 850 mm.After building frame, it is checked for bend, which may be produced while assembling cross members to side member. It is made to inspect frame assembly line and rectification also made on this stage.For conforming whether bend is present or not in frame stretchable thread is use and if there is end of specification of 0.5mm per meters then frame having this much bend would be allowable. Direction of bend present in both side members is in the same direction then maximum of two is considered. And if the bend present in two side members are in opposite direction then their summation is considered. And if bend present is in wavy form then two summation would be considered and maximum of these summation would be considered. So this is general method used for inspecting amount of bend present in frame. Specifications of some of frame models that have been built in
ASHOK LEYLAND ALWAR are given below.

LAY DOWN
The lay down stage is the very stage of the framing stage. It comprises three distinct stages and the working of these stages varies model after model. Generally the work carried out at this stage Consists of assembly front and rear axle on chassis along with springs.Generally chassis are made to available with three kind of suspension system. These are mechanical suspension, Weller suspension, air/ webller suspension. Ordinary chassis are equipped with mechanical kind of suspension, as CNG chassis are equipped with Weller kind of suspension as CNG chassis have to bear heavy load of 12 cylinder of CNG, and last kind of suspension are employed on luxury chassis as this suspension is known for its absolute shock free comfort. The procedure for mounting of mechanical kind of suspension is followed:Passenger models, like 203 cheetah passenger chassis (6 wheeler) have processing stages, are as follows:
1. Axle dressing 2. Axle coupling 3. Torque stand So a brief description regarding process for passenger chassis carried out at this stage is mentioned below.
AXLE Dressing:-
In this stage front and rear axles are assembled with leaf spring. The front leaf spring are assembled on front axle with I bolt and nut having inserted packing plates and shocker plates on which shockers are mounted.On the other side the rear leaf spring is assembled with the help 9f U- bolt. The brake boosters are also assembled on rear axle at this stage while on the front axle brake chambers are already assembled previously.
Axle Coupling:-
At the coupling stage the front and rear axles assembled with leaf spring are coupled with frame. The coupling is done with the help of shackle pin, which inserts in bracket and hole of the springs. The shackle pin has a very min tolerance and that special type of key pin is made with taper arrangements so proper alignment is required to fix that pin in leaf spring with brackets of frame.
Torque stand:-
At the torque stand tightening of all the nuts that have been bolted on previous two stages are done as on previous stages components have been just assembled, lightly on frame. After tightening nuts the strength of their tightness is checked with help of impact wrench.Of all type of rear suspension used on with rear axle vehicle the non reactive suspension has been chosen owing to its simplicity and safe riding Characteristics. Theterm non-reactive means that under all static and dynamic conditions the suspension is self-compensating. Unlike the balance beam, this is not self-compensating under all condition. The other advantages offered by this suspension are;
1. It allows the load on spring of one axle tube shared by the springs of other when an uneven road surface is encountered and results in minimal vertical movement of frame. On the account of the load being always shared equally by the axles road damage is considerably reduced.
2. In normal twin rear axles vehicles while braking there is transfer of weight from front axle to back axle of the rear axle and thus can cause the wheels on forward rear axle to lave the road surface or at very least in loose tyre grip on road the result is loss in braking efficiency of vehicle But in non-reactive suspension the forward rear axle does not raise on braking preventing loss in brakin efficiency.
3. This suspension reduces the shock loads with resultant life extension chassis components.
So this simple arrangement provides lot of advantages.The arrangement includes trailing springs anchored at front end with load equalization b\w the axles through ball crank levers and connecting rod.
FRAME DRESSING:- At this stage tie rod is made to assemble on frame which is carrying two moveable parts called shackles to which front end of both rear springs would made to connect to brackets , and at axle coupling stage both rear axles come without having rear springs opposite to case of ordinary in which they comes along with rear springs. So firstly both rear springs are to made connected to tie rod and frame. So this is work that is carried out during lay down stage of multivalent vehicle such as 2214.

PIPING STAGE:-
As name suggesting work carried out on this stage consists of making pipe arrangement for bake system of chassis. At this stage whole ckt. Of brake sys. Is laid down on chassis with help of metallic pipes. The brake sys. Of all models of ASHOK LEYLAND VECHICLE has being designed by SUNDRA CLAYTON LIT. of Chennai, and name given to such arrangements called DUAL BRAKE SYSTEM. This dual brake sys. a split sys. of air brake to actuate front and rear foundation brake separately, there by insuring partial braking for vehicle
Working System:-As the system starts charging the preferential arrangement in SPV allow air in to service reservoir (primary/secondary) As the pressure reaches above opening pressure of auxiliaries in the sys. the auxiliaries line start charging. As long as the sys. Pressure is below he opening pressure of the auxiliaries, the hand brake is inoperative and the spring brakes are applied condition.As soon as the compressor start’s pumping air in to the sys. & the sys. Pressure is below the opening pressure of auxiliaries, the low pressure indicator switch continue to give warning. The warning from the low pressure indicator switch stop’s when the sys. Pressure reaches above opening pressure of the auxiliaries & with lever of graduated hand release valve in BRAKE OFF position. In this position the spring brake in rear are fully released.So when the dual brake valve pedal is pressed, compressed air from the primary reservoirs fed into the service port (11) of he spring brake actuators through dual brake valve primary & applies brake in rear. Simultaneously compressed air in the secondary reservoir is fed into the brake chamber through the dual brake valve secondary & applies the brakes in fronts, foundation brakes are actuated by the slack adjusters connected to the brake chamber & springs brake actuators in the fronts & rear brake the brake chamber & springs brake actuators in the fronts & rear brake respectively.In case of releasing the load from pedal air from service port (11) of brake actuators through dual brake valve primary & applies brake in rear. Simultaneously compressed air in the secondary reservoir is fed in to the brake chamber through the dual brake valve secondary & applies the brakes in fronts. Foundation brakes are actuated by the slack adjuster connected to the brake chamber & spring brake actuators in the front & rear brake respectively.In case of releasing the load from pedal air from service port(11) of springs brake actuators is exhausted by dual brake valve. During
same time air from the brake chamber is exhausted through the dual brake valve thus releasing brake in front.So this is about working of DUAL BRAKE SYSTEM of chassis having single axle in case of multi axle drive working is quite similar ht only ht only difference is due to addition of some components. These components are only assembled incase of multi axle drive a little detail about these components along with components that are assembled in single axle chassis, which also assembled in multi axle, is give below.
RELAY VALVE:-
In air pressure braking system employing long piping running between brake valve and brake chamber relay valves are used the signified by brake valves. The relay is connected to reservoir and air delivered to and release from brake chamber is passed through relay valve and only a small amount of air used to actuate relay valve is delivered and exhausted from brake valve. This gives quick braking response and also permits the same pressure to brake chamber as delivered by brake valve.
QUICK RELEASE VALVE:-
The component ensures faster exhaust of air pressure from brake chambers.
AIR FILTER:-
The component prevents dirt from reaching pipe line and valve in brake system. When air filter jammed due to dust then during suction of air, vacuum is created in air filter. There is a vacuum valve on the front penal of FES which is connected with air filter. Now due to jam in air filter, the spring inside the vacuum valve goes down, this gives indication to driver to clean the air filter.
BRAKE CHAMBER:-
The function of brake chamber is to convert energy of compressed air in to mechanical force and motion necessary to operate brake.
DUAL BRAKE VALVE:-This valve gradually charges and exhausts air from brake chambers and spring brake actuators. Dual brake valve has two brake valves assembled in tandem. When brake is applied the plunger moves the primary piston downwards closing the exhaust passage and subsequently opening primary inlet valve thus admitting compressed air in delivery line connected to spring brake actuators in rear and applies the brake.When brake is released the inlet valves in the primary and secondary closes inlet passage and opens the exhaust passage by the secondary piston end subsequently opens the inlet valve of secondary thus admitting compressed air in delivery line connected to brake chambers in rear and applies the brake.When brake is released the inlet valves in the primary and secondary closes inlet passage and opens the exhaust passage allowing the compressed air from brake chambers and spring brake actuators to atmosphere.
GRADUATED HAND RELEASE VALVE:-
This valve charges and exhausts compressed air gradually form spring brake actuators for releasing and applying parking brake.
SPRING BRAKE ACTUATORS:-
THIS COMPONENT products necessary braking force at the foundation brake in service & hand brake application .This unit has diaphragm type brake chamber operation service brake connected port(11) & a spring brake operating the parking/hand brae connected port 12.When air pressure is applied to service port11 diaphragms flexes & operates the push rod which in turn moves slack adjuster to operate foundation brake. The spring brake portion when hand brake valve is operated, air pressure from spring brake portion is exhausted to atmosphere &heavy coil spring pushes the push rod through diaphragm sand brakes are applied.
SILENCER-
All vehicles of ASHOK LEYLAND Ltd. are double silencer which reduces noise pollution at higher extent. It is all about brief description about working & functions of components assembled in vehicles. So at this stage lay down of all this components connecting through pipes is laid down along with connection of components by using air hoses & metallic pipes certain
Other components are assembled on this stage such as oil Bundy pipes all this which senses pressure of oil in engine & pressure of air in two tanks are connected tr. Hydraulic pipes which is connected to Hyd. Reservoir coming from stg. Box also leakage of whole arrangement is checked.
ENGINE MOUNTING 1
The next that lies during assembly operation is engine mounting 1 work carried out during this stage include following fitments of components .
FITMENT OF PROPELLOR V SHAFT:-
Previously a dressed propeller shaft that is dressed offline is mounted on chassis. Two propeller shafts (P.P.S.) refitted case on heavy vehicle & in case passenger three PPS are fitted. So we take general case of two PPS. Two PPS are fitted b/w gear box & rear axle supports by center bearing at center. The front shafts have a fixed joint near gear box & rear end is supported on center bearing with a splinted stub shafts to take up rear propeller shafts. The rear shafts consists of fixed joints at rear end a slip joint at free end for a longer end trouble free life these joints are to be lubricated periodically.
ENGINE MOUNTING:-
As the name given to this stage because of figment of this components. Previously dressed engine whose dressing is done off line with could plate, pressure plate & some other accessory made available to online & at this stage it is mounted.After fitting engine on chassis no. of connection of different components to engine is made connection such as asir cleaner which provide supply of air to engine if modal is of passenger then air cleaner is directly mounted to engine if it of heavy then air cleaner is the separate unit exists which is assembled to engine by a pipe going to intake manifold of engine.Second connection is of tail pipe coming out through exhaust manifold & a head of this a silencer is mounted a head of which an exhaust pipe is fitted. Other connection is of fuel hose from diesel tank to feed pump that already mounted on engine, return fuel hose fro governor to fuel tank. This component that assembles here on chassis is radiator to engine, is which is also previously dressed off line connection of radiator to engine, is made through hose that are of radiator. One hose goes to engine it serves as inlet to engine second hose comes
from engine to radiator which act outlet for coolant & third hose that comes from diesel tank also act inlet hose of one way type outlet hose come through a thermostat valve which opens at definite temp. so until this temp. is achieved coolant cant go through engine. The basic function of thermostat valve is to support engine to attain its working temp. as early as possible.And last component fitted is steering column to steering box. Steering column is connected to steering box through knuckle joint in case of CNG many other components are assembled on chassis at this stage components like first stage regulator, second stage regulator are mounted on chassis .The function on these components is to reduce pressure of CNG which is filled in cylinders at a pressure of these components is to reduce pressure of CNG which filled in cylinder at a pressure of 200 bar to 9 bar So first stage regulator pressure reduces so drastically results in decrease in temperature which may result in freezing of CNG so to avoid this two pipes are made connected to this components which carries hot water from engine & circulates around it so that the above case may happen.
ENGINE MOUNTING 2
This is a next stage lie during assembly line. In case of assemble of ordinary chassis this stage is not much us. This stage comes in to its full operation in case of CNG chassis assembly. In case of assembly of ordinary chassis work carried out is composed of bumper, mounting of Head lights along with indicator lights so not tool much work is carried out.
In case of CNG work carried out consists of various small tasks these includes connection of 3 WAY SOLENOID SWITCH Along with connection of hot water hoses to first stage regulator, connection of first stage regulator to second stage regulator, Along with this joining of spring brake actuators to the slack adjustor. Connection for hydraulic system is made i. e. one hose is connected from hydraulic rear oil to steering box &second hose is connected to hyd. Pump. Other outlet of hyd. Pump is made to connect with steering an one hose from steering goes into the hyd. Pump so with this arrangement hyd. Oil keeps circulate from hyd. Reservoir to steering with help of hyd. Pump. Along with this mounting of bumper & head and indicators light is done. A steering column is connected to steering box through universal joint. The most arduous task performed here dismounting CNG cylinders on the chassis .12 cylinder each are having capacity of about 9 it. Is mounted on chassis in from of to channels each carrying 6 cylinders. At the outlet of each cylinder a valve is connected which act as a safety cum delivery
valve. The purpose of this valve is to provide safety case of leakage of CNG from cylinder. In case of leakage the safety valve would be open & through ventilation arrangement gas would disperse in to atmosphere. Gas piping arrangement for supply of CNG from all the hoses are made up of CDS and are very costly about 300/- per ft. so passing the transducer supply goes into first stage regulator. Also arrangement for ventilation is made at this stage hoses from the safety portion of valve are connected to tow hoses one for each side consisting of 6 cylinders and these tow hoses are left open for further connection where there would be further connected to tow main pipe which opens in air at rear side of chassis. As CNG is lighter then air it would readily diffuse in air as comparison to LPG which is heavier than air and in case of leakage it accumulates near to area of dispersion so in this case CNG in safer fuel then LPG.
LUBRICATION:-
As name suggesting the kind of work done during this stage is filling of oil to the various components of chassis and application pf grease to grease nipples so that operation of all these parts may take place smoothly with least friction so top ensure their long life. The work carried out on this stage mainly consists of oil and application no grease to components chassis. And wheels mounting on both front and rear axles are also done on this stage.Different type of oil is filled in number of components engine oil is filled in engine, gear oil in gear box, rear axle, hydraulic oil in steering box and addition of filling of DIESEL in fuel tank is also done about 20 Lt of diesel is filled in fuel tank and filling of water in radiator is also done. And application of grease to all grease nipple is done grease is applied to grease nipple until it starts to come out from other part of nipple. Tightening of all wheel bolt which are mounted on both front and rear axles is done keeping the torque of 400 lb. ft.
In radiator, The ratio to coolant & waters in for passenger vehicle-3:7For Goods vehicle 1:1Specification of oil changes from model to model and also from season to season. Quantity of oil also varies from model to model.
OFFTRACK 1
This is next stage that lies after lubrication stage in sequence of assembly line. At this stage wooden trame on which driver seat has been mounted is made to mount of chassis. Wooden str. Is made to mount in case of ordinary chassis but in case of chassis for heavies a steel str. Takes place of wooden str. Called FES (front-end Structure). Generally it can be said as cabin with no roof but having all features which have to be made available around driver such as dashboard having all displays, horn, steering wheel, head light, indicator light, acc. Pedal, brake pedal, clutch pedal, wiper motor. This str. is made to mount on chassis which one is needed. In addition of mounting of str. two batteries of 12 volt each is made to mount on chassis and +ve of one battery is made to connect with –ve of second battery thus providing series connection and –ve terminal of first battery is earth connected thus avoiding the danger of lcaage and +ve of second battery is made to connect with starter motor. And in addition of this a pedal is made to link with throttled valve. And incase of CNG filling of gas to all 12 cylinder is done. So this much amount of work is done at this stage.
OFFTRACK 2
This is last stage that lies during assembly operation. The chassis is made to run for very fist time. The work carried out at this stage involves connection of all electrical equipment. In addition to above task another operation which are preformed at this stage are mounting of steering wheel to steering column, mounting of dash board having all displays which will be further connected to respective components. Also max. cut is given to chassis at this stage. The purpose behind this is to set maximum limit to which a vehicle can take turn. The chassis is given so such limits by adjusting max cut screw mounted on front axle by adjusting the distance between outer edge of chassis and leaf spring of front axle. This is set at 505 inch. In the case of power steering another cut is also given in addition to max cut and this is called hydraulic max cut. The purpose behind this cut is to introduce safety factor. In case of hydraulic max cut the additional setting is done by keeping a distance of 3 mm between axle beam and front axle whether in former case i.e. in mech. Max cut axle beam and max cut screw touch each other.
And in last chassis is made to start for first time. All kind of leakage is checked along with proper functioning of each road testing.
ROAD TESTING
So it is testing time for chassis. After coming from assembly line chassis is first time subjected to run on road. A testing of about 15 Km is given to chassis and during this 15km functioning of all components comes under observation. And after completing drive road tester made ROADTEST INSPECTION REPORT in which he motions defects that has been occurred during drive. The general area where defects are found to develop arête chances of oil leaks in engine, gear box, rear axle, steering box, power steering, diesel leaks, radiator leakage, propeller shaft leakage. And in addition to oil leakage functioning of brake system of chassis is observed. Observation regarding whether brake drum are over heating, hand brake functioning produced in various components are examined whether any axle noise, water pump noise, timing gear noise are observed overheating of engine and remark regarding pick up is also mentioned in inspection report.
PRE DELIVERYINSPECTION (PDI)
As name suggesting function of this department is to rectify all defects in chassis, which may be left online and have been developed after road testing. In addition of rectifying other task involved filling of coolant in radiator by replacing water. Trouble shooting for some din d of defects which are found in chassis are done as for if engine is not starting then possible reason may be one or more of following (insufficient gas pressure in CNG chassis, starter motor not working, insufficient air flow to carburetor and many more.)So after finding the fault the cause for fault is find out and rectified by workers of this department. In addition of rectifying all defects present in chassis specified work of this department is following:-
1. Start engine and build air pressure to 8.25 Kgf/cm.2. Check leak from pipe joints and valve with soap and rectify
if any.3. Tight all drain plug 4. Check ignition timing and adjust if required 5. Remove about 13 Lt. of water from radiator and fill coolant
of specified quantity.6. Cover dashboard with polythene.
So this is general work carried out by PDI department both QC and PRODUCTION department.
