27) Install the opposing pinion (2) into the opposite crank socket. It may be necessary to tap on the back side of the rack to allow the insertion of the pinion. Caution must be exerted when installing the pinion not to damage the rack teeth. If the pinion will not install easily into the socket, then adjust rack positions to ease insertion. Do not hammer pinion into place, light tapping is acceptable.

LWCV VALVE STACK ADJUSTMENT INSTRUCTIONS For non-integrated style manifolds Refer to Canrig drawing numbers AY11920-1 & AY11920-2
1) Locate test port located on “A” side of the LWCV hydraulic valve stack assembly. This will be the test port for the high pressure side of the LWCV hydraulic system- note that the high pressure side must be set before the low pressure side is set.
2) Remove protective cap from test port and install gauge fitting to test port. 3) Locate the high pressure reducing valve in valve stack- it will be the valve
directly under the directional valve. Remove protective cap and loosen the locknut securing the adjusting screw.
4) Function actuator open and closed. Note pressure reading on gauge-regulate the adjusting screw in order to obtain the proper pressure reading. The pressure should be set to 1300 psi. Continue to operate the actuator as required to maintain pressure in the system.
5) Once the correct pressure is obtained, hold the adjusting screw in position with the hex wrench and tighten the locking nut.
6) Operate the actuator to verify that the pressure is correct. 7) Remove pressure gauge from the test port and replace the protective cap. 8) Replace the protective cap on the pressure reducing valve. 9) Locate test port located on “B” side of the LWCV hydraulic valve stack
assembly. This will be the test port for the low pressure side of the LWCV hydraulic system.
10) Remove protective cap from test port and install gauge fitting to test port. 11) Locate the low pressure reducing valve in valve stack- it will be the valve
directly under the previously set high pressure reducing valve. Remove protective cap and loosen the locknut securing the adjusting screw.
12) Function actuator open and closed. Note pressure reading on gauge-regulate the adjusting screw in order to obtain the proper pressure reading. The pressure should be set to 650 psi. Continue to operate the actuator as required to maintain pressure in the system.
13) Repeat steps 5 – 8 as shown above to complete setting the low pressure side of the LWCV system.

For integrated style manifolds Refer to Canrig drawing number AY11920-3
14) Locate test port labeled ‘GA-5’ on hydraulic manifold assembly- it is located directly under the LWCV valve stack on the hydraulic manifold. This will be the test port for the high pressure side of the LWCV hydraulic system- note that the high pressure side must be set before the low pressure side is set.
15) Remove protective cap from test port and install gauge fitting to test port. 16) Remove protective cap from high pressure reducing valve (located in the
hydraulic manifold body- labeled ‘20E’). Loosen the locknut securing the adjusting screw.
17) Function actuator open and closed. Note pressure reading on gauge-regulate the adjusting screw in order to obtain the proper pressure reading. The pressure should be set to 1300 psi. Continue to operate the actuator as required to maintain pressure in the system.
18) Once the correct pressure is obtained, hold the adjusting screw in position with the hex wrench and tighten the locking nut.
19) Operate the actuator to verify that the pressure is correct. 20) Remove pressure gauge from the test port and replace the protective cap. 21) Replace the protective cap on the pressure reducing valve. 22) Locate test port labeled ‘GB-5’ on hydraulic manifold assembly. This will
be the test port for the low pressure side of the LWCV hydraulic system. 23) Remove protective cap from test port and install gauge fitting to test port. 24) Locate the low pressure reducing valve in the LWCV valve stack- it will be
the valve directly under the directional valve. Remove protective cap and loosen the locknut securing the adjusting screw.
25) Function actuator open and closed. Note pressure reading on gauge-regulate the adjusting screw in order to obtain the proper pressure reading. The pressure should be set to 650 psi. Continue to operate the actuator as required to maintain pressure in the system.
26) Repeat steps 18 - 21 as shown above to complete setting the low pressure side of the LWCV system.

LWCV CHECK VALVE INSTALLATION INSTRUCTIONS
Procedure for installing check valve in LWCV hydraulic valve stack
1) Relieve pressure on system by turning HPU off. Lock out HPU as necessary to prevent start-up during the check valve installation.
2) Relieve pressure on system by operating link tilt or other hydraulic function.
3) Thoroughly clean valve stack and manifold around valve stack to eliminate contamination of hydraulic system.
4) Remove solenoid from top of valve stack. 5) Remove four nuts from retaining studs on valve stack. 6) Remove all valves (proportional valve and pressure reducing valve(s) from
valve manifold. Note location of each valve as it is critical that they are reinstalled in their original orientation.
7) Unscrew four studs from hydraulic manifold and discard. 8) Screw new longer studs (supplied with kit) into manifold block. Note that
the studs supplied with the Rexroth valve kit are not interchangeable with the shorter Sun valve kit studs.
9) Identify check valve supplied with kit- refer to Figures 1a and 1b. (Due to availability of check valves, Canrig may supply either style valve as shown with kit -valves are fully interchangeable.) Pay particular attention to the orientation of the valves during installation.
Figure 26a
Sun Check Valve
Figure 1b
Rexroth Valve
10) Canrig manifolds assemblies vary in design depending upon the Top Drive model. Refer to Figures 2a and 2b to determine proper orientation of valve and manifold style. Sun style valve is shown in illustration - Rexroth installation is similar EXCEPT that orientation is accomplished with alignment holes rather than notch alignment (see Figure 3). Note that manifold components as shown in Figure 2 may vary slightly from illustration.
