CANRIG LWCV ACTUATOR ASSEMBLY

Clean all machined surfaces with Varsal, Bright Clean or equivalent.

1) Install the ball bearing (17) into the bearing housing (6) using a rubbermallet until firmly seated.

2) Install the bearing retaining ring (18) into the groove in the bearing housing(6).

Figure 1

3) Repeat above two steps (1 & 2) for the second bearing housing.

4) Install one labyrinth ring (13) onto each of the two inner sleeves (4) ensuring

that the tapered surface is facing the side where the racks are present.

Figure 2

5) Place the bearing/ housing assembly onto the inner sleeve (4) and use arubber mallet to tap on the top of the bearing inner race until the bearinginner race is seated on the inner sleeve.

6) Install one plug (54) and one grease fitting (20) in the bearing housingassembly.

Figure 3

7) Grease the bearing through the grease fitting while rotating the bearing.Visually ensure that the grease fills the bearing consistently and that no dryareas exist in the bearing.

8) Repeat the same for the other bearing housing assembly and inner sleeve.

9) Install the Guide Sleeve (7) into the ID of the inner sleeve (4) until it isseated on the lower shoulder and that the tab on the end of the guide sleevefit properly into the notch in the inner sleeve.

10) Install the plain bearing strip (19) into the ID of the inner sleeve (4) until it isseated on top of the guide sleeve (7).

Figure 4

11) Repeat step 9 & 10 for the other inner sleeve.

12) Place bearing retainer (5) on top of the bearing housing (6), ensuring that allsix holes are properly aligned with holes in the bearing housing.

13) Install the six 3/8 socket head cap screws (21) and lock washers (22)ensuring that all threads are coated with Loctite 242. Torque to 40 ft. lbs.Install safety wire (36) and ferrules (37) through all bolts.

14) Install the wiper (16) into the ID groove of the bearing retainer (5).

Figure 5

15) Repeat steps 12, 13 & 14 for the other bearing housing/ inner sleeveassembly.

16) Install the inner sleeve/bearing housing assembly onto the mounting sleeve(3) - slide the assembly down until the top of the bearing retainer (5) isapproximately flush with the end of the tapered portion of the mountingsleeve.

Figure 6

17) Turn the assembly over and repeat step 16. Use the pinion (2) to space theracks in the approximate location- the hole in the mounting sleeve (3)should be located between the racks at this time.

LWCV VALVE STACK ADJUSTMENT INSTRUCTIONS

For non-integrated style manifoldsRefer to Canrig drawing numbers AY11920-1 & AY11920-2

1) Locate test port located on A side of the LWCV hydraulic valve stackassembly. This will be the test port for the high pressure side of theLWCV hydraulic system- note that the high pressure side must be setbefore 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 valvedirectly under the directional valve. Remove protective cap and loosenthe 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 theactuator as required to maintain pressure in the 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 asnecessary to prevent start-up during the check valve installation.

2) Relieve pressure on system by operating link tilt or other hydraulicfunction.

3) Thoroughly clean valve stack and manifold around valve stack to eliminatecontamination 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) fromvalve manifold. Note location of each valve as it is critical that they arereinstalled 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 thatthe studs supplied with the Rexroth valve kit are not interchangeable withthe shorter Sun valve kit studs.

9) Identify check valve supplied with kit- refer to Figures 1a and 1b. (Due toavailability of check valves, Canrig may supply either style valve as shownwith kit -valves are fully interchangeable.) Pay particular attention to theorientation of the valves during installation.

Figure 26aSun Check Valve

Figure 1bRexroth Valve

10) Canrig manifolds assemblies vary in design depending upon the Top Drivemodel. Refer to Figures 2a and 2b to determine proper orientation ofvalve and manifold style. Sun style valve is shown in illustration - Rexrothinstallation is similar EXCEPT that orientation is accomplished withalignment holes rather than notch alignment (see Figure 3). Note thatmanifold components as shown in Figure 2 may vary slightly fromillustration.
