Crankshaft Seal 155 x 180 x 15
Volvo

Crankshaft seal designed for Volvo heavy-duty engines, specified by inner diameter 155 mm, outer diameter 180 mm, and cross-section 15 mm. This seal provides a robust barrier between the rotating crankshaft and stationary engine components, preventing oil migration into timing covers or external areas. The assembly typically features a resilient elastomer lip with a spring-loaded sealing edge to maintain contact through thermal expansion, vibration, and rapid temperature changes. Correct installation ensures even seating against the crankshaft journal and housing, reducing leakage risk and prolonging service life. The material is chosen for compatibility with engine oil, additives, and elevated temperatures common in long-haul operation, contributing to lower oil consumption and cleaner engine surroundings. For best results, verify surface finish and cleanliness of the mating bore and use proper installation tools to avoid lip damage. Source One Parts Center
