Preventive Maintenance 2011

• PM▬Preventive Maintenance▬Predictive Maintenance▬Proactive Maintenance

The most important maintenance operation we performThe front line to controlling maintenance costs


• Where To Start?

▬What do you want from your PM Program?• Lube, Oil & Filter Change?• FHWA Compliant Inspection?• Aggressive Preventive

Maintenance Tool!


• Overall Program Goals▬Provide a Safe & Reliable Vehicle▬Reduce / Eliminate Unscheduled

Maintenance▬Extend Vehicle Life▬Control Maintenance Costs

Increase Customer Satisfaction


• A Good PM Program Should Be Constantly Evolving

▬Specification Changes▬Technology Changes▬Reactive to Problem Areas


• Effect of Spec / Tech Changes▬New components that require preventive

maintenance▬New components that eliminate the need for

preventive maintenance▬PM maintenance required by new systems &

technology▬Preventive / predictive maintenance information

provided by new technology


• Reacting to Problem Areas▬What part or component failure patterns are you

seeing that can be detected during the PM inspection?

▬Review road failures. Many are PM preventable▬Monitor unscheduled maintenance. What is

preventable?


• Reacting to Problem Areas▬Look at top 50 parts used other than PM

parts• Are these parts being inspected at PM time?• Should they be?• Could a specification change eliminate this

failure?• Is there a better choice for a replacement part?• Is there a better maintenance practice to

reduce these failures?


• Technician Involvement & Input▬Are there defects that they find that are NOT on

the inspection checklist?• Should they be added?

▬Are there items on the inspection list that are never or very rarely found defective?

• If not FHWA required, should they be removed?


• PM’s & 2011 Emissions

• The new technology will require Preventive Maintenance & Inspection

• Additional Maintenance & Inspections can be:▬Manufacturer Specific▬Application Specific▬Specification Specific



• Inspection Items to Consider:▬DPF Inspection▬ Forced / Parked Regen▬Pressure Differential Tubes▬Crankcase Coalescing Filters▬ 7th Injector Inspection & Cleaning



• Inspection Items to Consider:▬SCR components, leaks & condition▬Emphasis on Cooling System & increased system

demands• Pressure cap condition• Proper coolant• Clean radiator & charge air cooler• Variable speed fan operation



• Inspection Items to Consider:▬High Pressure Common Rail Fuel Injection

• Pressurized fuel filters• Close inspection for leaks & condition

▬Make sure your Technicians are trained on the hazards associated with these systems



• Inspection Items to Consider:• Increased attention to electrical systems

– Increased electrical system demands– Increased hotel loads– Sensitive electronic components



• Inspection Items to Consider:▬Electronic Information

• Trip data downloads• Active & inactive fault code review• Parameter verification• Most current programming version



• Other Items to consider▬Air Driers▬Cabin Air Filters▬Diesel & Battery APU’s▬Coolant filters▬End of warranty period PM

• All Require Teamwork & Communication with Truck OEM’s & Component Manufacturers!


• PM Ergonomics▬Develop & list inspection items▬Group items to achieve good “PM flow”

• Pre PM inspection & walk around• In cab inspection & road test• Under hood inspection• Under chassis inspection• Special equipment• Bodies & lift gates• Post PM inspection & road test if required


• PM Ergonomics▬No one inspection form fits all

• Differ by vehicle type & application• Differ by vehicle and component manufacturer• Differ by operating environment and

geographic location▬TMC has a great form to work with▬Other Nationalease members are a great

resource!!


• PM Ergonomics• Shop Ergonomics

– Dedicated PM areas– Access to PM tools, equipment, & parts– Oil sampling equipment & procedures– Used oil evacuation & disposal– Used filter handling– Clean filtered fuel for suction type filters– Under vehicle access, lifting equipment


• PM Training & Certification

• Develop a PM Narrative▬Explain each inspection point and procedure in

detail▬ Include instructions on proper completion of

inspection forms▬ Include procedures for reporting needed follow up

repairs▬ This is a great training tool also


• PM Training & Certification

▬Technician Training & Certification• All Technicians performing PM inspections

must meet the certification as outlined in FMCSR Part 396.19

• In house certification is allowed• ASE PMI Certification is recommended• Must be Air Brake Inspector qualified as

outlined in FMCSR Part 396.25


• PM Documentation▬Each vehicle must have documentation of

current FHWA Inspection within the past 12 months in compliance with FMCSA Part 396.17 (c) • Copy of last inspection report• Compliant PM sticker or decal


• PM Documentation• Motor Carrier Responsibility

– The original or copy of the PM inspection form must be retained for 14 months in compliance with FMCSR Part 396.21

– We retain for 7 years after we sell the vehicle!


• PM Compliance▬Regardless of the quality of the program &

procedures it all comes down to • COMPLIANCE

– Are PM’s performed on time?– Do you benchmark PM on Time

Performance?– Do you have a Management PM Quality

Assurance Program in place?– Do you recognize & reward Technicians?


• Closing Comments• A cutting edge PM Program

– Is constantly evolving– Requires communication & teamwork– Will insure a safe & compliant vehicle– Will reduce overall maintenance expenses

• Is The Foundation For Customer Satisfaction
