ACS UHT55 Crankshaft Oil Seal, Air Compressor Pump Part UHT5563
A weeping crankshaft seal is the usual reason a pump leaves a film of oil on the belt guard and slowly drops its sump level. The seal rides on the crankshaft behind the flywheel, so it sees shaft speed and heat continuously and hardens with age. It is a cheap part to fit while the flywheel is already off for a belt or bearing job.

Service notes
Check the shaft sealing surface before fitting. A groove worn into the shaft by the old seal will leak straight through a new one. Lightly oil the seal lip on assembly and press the seal in square so the lip is not rolled under.
Typical applications
Oil leaks at the flywheel end and sump level loss on ACS UHT55 pumps in shop, fleet and light industrial reciprocating compressors.
The ACS UHT5563 crankshaft oil seal is the genuine shaft seal for the UHT55 air compressor pump, supplied by AirComParts as part number U2040.
