PROBLEM

Show/hide table

The tilt cab locking plates and ROPS bolts need to be reworked on certain 953D and 963D Track Type Loaders. The existing plates do not allow the safety pin to be engaged. This pin secures the cab in the tilted position (90 degrees). Servicing a machine without securing the cab in the tilted position may result in personal injury or death. The ROPS bolts also need to be checked for torque. Operating a machine without proper ROPS bolt torque can result in personnal injury or death during a rollover event.
