One stop procurement crankshaft oil seal with OE number 11141706785 is an essential engine sealing spare part specially used for BMW N46 engine series. Manufactured strictly based on OEM mold and dimensional standards, this oil seal adopts high-performance FKM fluorine rubber material, which features excellent high temperature resistance, strong resistance to engine oil corrosion and great anti-aging ability. It can steadily withstand the high temperature and oil vapor environment at the crankshaft rear end for long-term operation.
With built-in reinforced metal framework and high elastic stainless steel tension spring, the sealing lip fits tightly against the crankshaft journal all the time. It effectively prevents engine oil leakage from the crankshaft rear end, and blocks external dust and muddy water from entering the crankcase, protecting the crankshaft and bearing assembly from abnormal abrasion. If the original oil seal becomes hardened, cracked or fails to seal, obvious oil dripping, increased oil consumption and dirty engine rear housing will occur.
Every product passes air tightness leakage test, compression permanent deformation test and high-low temperature aging test before delivery. Fully consistent with original size, it can be installed directly without cutting or modification. We provide one-stop auto parts sourcing service with abundant spot stock, support bulk wholesale, mixed batch orders and global fast delivery. Widely recognized by BMW maintenance stores and auto parts distributors worldwide, it is a reliable replacement to solve rear crankshaft oil leakage of BMW N46 engines.
