PROBLEM

Show/hide table

The existing shaft of the 244-8477 Pump Group may fail due to insufficient strength against torsional vibration on certain 322C and 325C Excavators. When the shaft fails, unwanted thrust is generated, and may result in damage to engine components such as crankshaft, crankshaft thrust bearings, and main bearings.
