HARNESS AS-PUMP 3032994 - Caterpillar

Make sure the machine is on level ground. Stop the engine, and move the control lever to make sure the weight of the bulldozer blade is on the ground. Move the control lever backward and forward to release the pressure in the hydraulic system. Slowly, loosen the cap to release any pressure in the hydraulic tank. Let the hydraulic oil become cool before any lines are disconnected in the hydraulic system.
1. Disconnect tilt cylinder hose assemblies (1). 2. Fasten a hoist to the end of the lift cylinders.3. Remove the nuts and bolts (4). Remove caps (2) and the shims from rod assembly (2). Keep the shims and caps with the lift cylinder rod from which they were removed.4. Retract the lift cylinders, and remove the hoist. 5. Position tooling (A) under push arms (6) as shown.6. Remove caps (5) from the push arms.7. Start the engine, and carefully back the machine away from the bulldozer. The following steps are for installation of the bulldozer. 8. Position tooling (A) under push arms (6) until the center of the bearings is 54.6 cm (21.5 in.) from the ground (Dimension X).9. Slowly, move the machine into position between the push arms until the trunnions are in position in the push arm bearings.10. Install caps (6).11. Connect tilt cylinder hose assemblies (1) to the elbows.12. Fasten a hoist to the rod end of the lift cylinders. Support the weight of the cylinders with the hoist.13. Extend the lift cylinders until rod assemblies (2) are in position on the trunnion balls on the bulldozer blade. Install an equal amount of shims on each side of caps (3) to obtain 0.3 to 0.8 mm (.01 to .03 in.) clearance between the cap and the bulldozer trunnion ball.14. Put the shims and caps (3) in position on rod assemblies (2), and install bolts (4) and the nuts.Disassemble Bulldozer
