Rework Procedure

Show/hide table

1. Perform the procedure outlined in RENR8681 Disassembly and Assembly-Cab-Remove to prepare the cab for lifting and blocking.

NOTE: The following items will not need to be removed/disassembled: the coolant, the electrical connections on the rear of the cab, the air conditioning and heater lines, the brake control valve, and the emergency brake cable.

2. Remove and retain the 8T-6624 bolt, 7X-0593 washer, and the 9U-0512 washer from each mount.

3. Lift the cab 152.5mm (6 inches) and install blocking under the cab. Monitor the lines as the cab is lifted in order to ensure that the lines are not being stretched or deformed. Remove additional clips in order to provide slack if harnesses or lines require it. Place blocks under the cab to secure it and still allow access to the cab mounts.

4. Remove and discard the existing 311-2178 mount assemblies from the machine.
