Show/hide table

Personal injury can result from driveline torque windup under load. Unequal wheel speed can result in driveline torque windup which can cause driveline components to be under load during disassembly. Relieve the driveline torque windup before disassembly.

1. Release the driveline torque windup by raising either side of the machine until the wheels are off the ground. Lower the wheels back to the ground.

2. Chock the wheels in order to stabilize the machine for maintenance.
