Problem

The cab mounting bolts need to be tightened on certain 928G Wheel Loaders and IT28G Toolcarriers. The 7X2567 Bolts and the 8T4001 Nut used to mount the cab to the engine-end frame may come loose due to improper tightening during assembly. The 8T4001 Nuts on the front mounting bolts could come off the machine.

Parts Needed

2 - 8T4001 Nut

2 - 8T4167 Washer

Action Required

1. Pull back the cab floor mat in the vicinity of the front mounting bolts and also remove the plugs on the access holes in the floor.

2. Next remove the lockable storage compartment in the right rear corner of the cab and the parking brake cover in the left rear corner of the cab after removing the 9X2042 Truss-Head Screws. (Reference 1253963 and 1414986 Liner Groups - 3 screws on each side. The liners in the cab posts may have to be removed as well.)

3. Now you can access all four 7X2567 Bolts. Tighten the four bolts to a torque of 800 ± 100 N·m (600 ± 75 ft-lbs).

4. Tighten the four bolts a second time. Some of the machines might be missing the 8T4001 Nuts and 8T4167 Washers at the front mounting bolts in which case you will need two pieces apiece of both the part numbers.
