Procedure for Shimming
Illustration 1 | g00494467 |
- Remove all the shims from assembly (1) .
- Install assembly (1) and cap (2) on trunnion (3) without the shims. Tighten the bolts and maintaining equal distance on both sides of the cap.
- Insert as many shims as possible into spaces (A) and (B) between the cap and the assembly.
- Add two additional shims to the total shims that are used.
- Install half the shims at location (A) and install the other half at location (B). Tighten the bolts to the proper torque.
- This allows the assembly to move on the trunnion freely within the specified tolerance.

Shipping Instruction for Lift Cylinders
Personal injury or death can result if the lift cylinder is not secured when the lift cylinder is being attached to the blade or detached from the blade. The lift cylinders can rotate freely rearward when the cylinder rod is retracted. Secure the lift cylinder until the cylinder rod is extended in order to prevent the lift cylinder from rotating rearward. |
- After you disconnect lift cylinders (34) from the blade raise the cylinders to the UP position.
- Start on the right side of the machine and remove bottom bolt (12) and locknut (15) from bar (17) on support (11) .
- Using bolt (12) and locknut (15) connect bar (17) to the boss on lift cylinder (34) .

- Pull hose assemblies (68) to the left side of the machine in order to remove slack. Torque bolts (78) to 105 ± 20 N·m (77 ± 15 lb ft).
- Connect the lift cylinders to bulldozer blade (63) with a cap, shims, four bolts, and four nuts. For instructions on shimming, refer to ""Procedure for Shimming"
".
Note: Items that are not numbered are part of the lift cylinder group.
Personal injury or death can result if the lift cylinder is not secured when the lift cylinder is being attached to the blade or detached from the blade. The lift cylinders can rotate freely rearward when the cylinder rod is retracted. Secure the lift cylinder until the cylinder rod is extended in order to prevent the lift cylinder from rotating rearward. |
Illustration 27 | g01309236 |
- Check the oil in the hydraulic tank and fill the oil, if necessary. Cycle the cylinders to full stroke in both directions in order to purge air from the lines and the cylinders. Refill the hydraulic tank to the FULL mark.
- After assembly is complete, prepare the machine for operation. Refer to the Operation and Maintenance Manual for instructions.
