PROBLEM

Show/hide table

The case drain hose is routed to the wrong port on the pump on certain 785D Off-Highway Trucks, configured as water spray trucks. This will prevent the case from filling with oil and can cause the shaft bearing to fail. This may allow hydraulic oil to transfer into the engine.
