PROBLEM

Show/hide table

In some instances the oscillating hitch thrust flange can loosen on certain 725, 730, and 730 Ejector Articlated Trucks resulting in damage to the flange threads. This can lead to excessive movement between the inner carrier and threaded flange. The threads may wear in service resulting in the flange parting from the carrier resulting in separation of the frames and may, in conjunction with other factors or circumstances, result in personal injury or death.
