Common Repair Uses

Oil seepage at the crankshaft seal area
Grease or lubricant loss from the sealing surface
Contamination entering the seal interface
Heat-related seal wear from poor lubricant circulation
Leak concerns after service on front engine sealing components

Installation Notes

Verify shaft diameter, housing bore, and seal width before installation. Inspect the sealing surface for wear, scoring, or contamination, and clean the bore thoroughly so the reinforced outer case seats evenly. On Audi A6 Quattro, Audi S4, and Volkswagen Touareg front applications, confirm the chassis-number notes before ordering.

Quality Assurance

Timken oil and grease seals are engineered with precision sealing geometry to control lubricant escape and keep contaminants out. The vented design helps manage heat at the lip, while the reinforced case and contamination exclusion features support consistent sealing performance in demanding engine applications.

This part fits 80 vehicles
