Mercedes Sprinter Front Crankshaft Seal – Elring | NCV3 3.0L OM642 | #2202700098 (2007–2018)
A leaking front crankshaft seal on a Sprinter OM642 allows engine oil to escape at the front of the crankshaft — contaminating the serpentine belt and surrounding components with oil that degrades rubber and accelerates belt and pulley wear. This is the Elring front crankshaft seal for NCV3 Sprinters equipped with the 3.0L OM642 diesel engine, a direct replacement that restores a leak-free seal at the front crankshaft snout.
What This Part Does
The front crankshaft seal is a radial shaft seal pressed into the front timing cover that contacts the rotating crankshaft front journal, preventing oil from escaping forward along the crankshaft axis. Elring is a premier OEM sealing manufacturer supplying radial shaft seals to Mercedes-Benz and other European automakers to factory specifications. When the seal's lip wears or hardens from age and heat cycling, oil seeps past the lip and is flung outward by the rotating pulley — coating the belt drive system and causing the oil contamination that degrades serpentine belts and shortens their service life.
Common Symptoms of a Failing Front Crankshaft Seal
- Oil residue at the crankshaft pulley area or behind the harmonic balancer
- Serpentine belt showing oil contamination or slipping under load
- Oil dripping from the front underside of the engine
- Belt squealing from oil on belt or pulley surfaces
When to Replace
Replace when oil leakage is confirmed at the front seal, or whenever the crankshaft pulley is removed. Always replace the serpentine belt if oil-contaminated.
