ACTUATOR 3859082 - Caterpillar

Start By:
Remove the track adjuster. Refer to Disassembly and Assembly Manual , "Track Adjuster - Remove".
Prior to disassembling and assembling the recoil spring assembly, make sure that Tooling (A) is on a level surface.
Thoroughly clean the outside surface of the recoil spring assembly prior to disassembly.

Illustration 3 g00561991
Note: Two adjustable supports (1) , reaction plate (2) , and movable plate (3) are part of Tooling (A) .
Position two supports (1) of Tooling (A) in order to support the recoil spring assembly. Make sure that the two supports are level.
Adjust the spacing between reaction plate (2) and movable plate (3) . The spacing is approximately the same length as the recoil spring assembly at free length.Note: Do not remove the lifting device from the recoil spring assembly until the unit is leveled, centered, and locked in Tooling (A) .Note: The recoil spring assembly may be installed in Tooling (A) from the end. In this case, reaction plate (2) must be removed. Then reinstall reaction plate (2) after the recoil spring assembly is in place on two adjustable supports (1) .
The weight of the recoil spring assembly is approximately 53 kg (117 lb). Fasten a suitable lifting device to the recoil spring assembly. Put the recoil spring assembly in position on two adjustable supports (1) in Tooling (A) . Adjust two adjustable supports (1) until the centerline of the recoil spring assembly and the centerline of Tooling (A) are aligned.

Note: The lifting device is removed from the recoil spring assembly for photographic purposes.
Put a level gauge (4) on the recoil spring assembly. Reposition the recoil spring assembly until the recoil spring assembly is level. Reposition the recoil spring assembly until the retaining rod and the nut are centered in the hole in reaction plate (2) . After the recoil spring assembly is leveled and centered, install two pins (5) on the back side of reaction plate (2) , as shown. Operate Tooling (B) enough to hold the recoil spring assembly in position between reaction plate (2) and movable plate (3) . Make sure that the recoil spring assembly is level and centered.

Personal injury or death can result from recoil spring force. Recoil spring force, if not relieved, can result in personal injury or death.Relieve spring force before removing threaded retainer, performing repairs on recoil spring housing, or removing recoil spring.See Service Manual for disassembly instructions. Maximum pressure is 20 700 kPa (3,000 psi).
Remove bolts (15) and strip (14) from nut (7) . Use Tooling (D) to remove nut (7) and washer (8) from the end of bolt (9) .Note: Slowly release the pressure on Tooling (B) in order to allow spring (12) to relax.
Open the covers on Tooling (A) . Fasten a suitable lifting device to the disassembled recoil spring assembly. Remove the reaction plate in order to remove the recoil
