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) ensuringthat 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.

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.

18) Ensure that the valve (1) is in the closed position (see Figure 9).
19) Standard valve only (see Figure 8a): Place the valve (1) vertically on thebox end. Install a retaining ring (15) into the upper groove on the OD of thevalve body. Turn the valve body over to sit on the pin end. Install the stopring (30) until it rests on the pin end retaining ring (15).
20) Install two o-rings (14) into the two middle o-ring grooves on the OD of thevalve body.
Figure 8a
Standard 7.70 OD Valve
21) Grease the o-rings prior to installing the mounting sleeve (3).
22) Note: it is important at this time to verify the timing of the valve with theactuator. This can be done by looking at the crank socket- identify thesocket that opens the valve when it is turned counterclockwise. The upper

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

LWCV VALVE STACK ADJUSTMENT INSTRUCTIONS
For integrated style manifoldsRefer to Canrig drawing number AY12341-1
1) Locate test port labeled GA-5 on hydraulic manifold assembly- it islocated directly under the LWCV valve stack on the hydraulic manifold.
This will be the test port for the high pressure side of the LWCV hydraulicsystem- note that the high pressure side must be set before the lowpressure side is set.
2) Remove protective cap from test port and install gauge fitting to test port.
3) Remove protective cap from high pressure reducing valve (located in thehydraulic manifold body- labeled 20E). Loosen the locknut securing theadjusting screw.
4) Function actuator open and closed. Note pressure reading on gauge-regulate the adjusting screw in order to obtain the proper pressurereading. The pressure should be set to 2200 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 positionwith 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 labeled GB-5 on hydraulic manifold assembly. This willbe 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 the LWCV valve stack- it will be
the valve directly under the directional valve. Remove protective cap andloosen 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 pressurereading. The pressure should be set to 1100 psi. Continue to operate theactuator as required to maintain pressure in the system.
13) Repeat steps 18 - 21 as shown above to complete setting the lowpressure 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 asnecessary 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 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 into manifold block.
9) Install check valve on manifold. Ensure that the alignment pin hole isaligned with pin hole in manifold for correct orientation- see Figure 1.
Figure 26
Mounting Side View10) Install previously removed valves in reverse order as noted in step 6.
11) Install hex nuts on studs and tighten.
12) Replace solenoid on valve stack.
13) Unlock HPU, turn on and check system for leaks. Cycle LWCV actuator toverify function.
