STEM AS-COLLET 2P3268 - Caterpillar

Caps (9) are free to fall when the lift cylinder is removed from the yoke. To prevent possible personal injury, remove the caps from the lift cylinder as soon as they are free of the yoke.
12. Carefully raise lift cylinder (7) high enough to remove the bearing caps.13. Remove bearing caps (9) from both sides of lift cylinder (7). 14. Carefully remove lift cylinder (7). The weight of the lift cylinder is 239 kg (525 lb) 15. If necessary, remove bearing (10) from bearing caps (9). Refer to steps a through c for the removal procedure.a. Use 3.0 mm (.125 in) low hydrogen welding rods (#7018). Weld a continuous bead completely around the inside diameter of the bearing.b. Allow the bearing to cool.c. Remove the bearing from the cap.Install Lift Cylinder
1. Use a press and Tooling (A) to install bearings (10) in bearing caps (9). The inside diameter of the bearing must be 88.87 0.10 mm (3.499 .004 in) after installation. 2. Attach a suitable lifting sling and hoist to lift cylinder (7).3. Carefully raise lift cylinder (7) in position. The weight of the lift cylinder is 239 kg (525 lb) 4. Lubricate the inside of bearing caps (9) with 5P-0960 Grease prior to installation.5. Install bearing caps (9) on both sides of lift cylinder (7). 6. Carefully lower lift cylinder (7) to the yoke and install bolts (8).7. Tighten bolts (8) to a torque of 370 50 N m (275 35 lb ft). 7. Connect hose assemblies (3).8. Connect harness connecters (4).9. Install hose clamp assemblies (5). Install harness clip (6). 10. Remove the chain that is securing the cylinder rod in position. 11. Start the machine and extend the lift cylinder rod to the blade trunnion.12. Turn the machine off.13. Install bolts (1) and bearing cap (2) without shims. Tighten bolts (1) until snug, maintaining an equal distance on both sides of the cap.14. Insert an equal amount of shims as needed in the spaces between the bearing cap and the lift cylinder assembly.15. Add one additional shim to each of the spaces. This should allow the assembly to move on the trunnion freely and within the specified clearance. The specified clearance between the trunnion and rod assembly is 0.50 0.25 mm (.020 .010 in)16. Tighten bolts (1) to a torque of 620 80 N m (460 60 lb ft).17. Separate the steering frame lock link. Refer to the topic "Steering Frame Lock Link, Separate & Connect" in this module.Disassemble Lift Cylinder
Start By:a. remove lift cylinder
Typical Example1. Put cylinder assembly (1) in position on Tooling (A) as shown.
Typical Example2. Put a mark on head (3) and the cylinder for correct alignment at assembly. Remove bolts (2).3. Put the stands [part of Tooling (A)] in position under the cylinder rod as support for the weight.4. Use Tooling (A) to pull the cylinder from the rod and head (3).
Typical Example5. Use Tooling (B) and the correct size socket to loosen
