Oil seal & water pump seal
Oil seals and water pump seals. Small parts, but the ones most often replaced alongside a pump or an overhaul, so tell us which job you're doing and we'll list what goes with it.
What to send us
The number stamped on the old part is the quickest route. If it has worn off, the engine or genset model and serial number usually gets us there. Photos help more than descriptions.
We cross-check whatever you send against the OEM catalogue and confirm the match with you before anything ships.
About this range
Crankshaft seals sit at the front and rear of the engine and keep oil inside it. The front seal usually starts weeping around the damper. The rear seal, between the block and the flywheel housing, is the one that drips onto the bellhousing and is often only found when a gearbox or an alternator drive comes off.
A water pump seal is a different item doing a different job: it keeps coolant off the pump bearing. When it goes, coolant escapes through the weep hole under the pump housing, which is the drain that exists to tell you exactly this.
Seals are sized to the shaft and the housing, not to the engine name, so a number off the old seal or the pump is worth more than the engine model on its own.
