Eaton Shaft Seal

Eaton Shaft Seal

This is a replacement input shaft lip seal for Eaton's 54 series heavy-duty hydraulic pumps. These pumps are frequently used to power the drum rotation on rear-discharge concrete mixers from manufacturers like McNeilus and Con-Tech. The seal prevents hydraulic fluid from leaking out of the pump at the point where the input shaft enters the housing. Replacing a worn or damaged shaft seal is critical for preventing fluid loss, maintaining system pressure, and avoiding catastrophic pump failure.
