C4890832 XCMG GR2605 motor grader oil seal

C4890832 is a genuine Cummins front crankshaft oil seal, a critical sealing component at the front of the engine crankshaft. Constructed with a fluororubber/nitrile rubber + metal skeleton composite structure and integrated dual-lip design (main sealing lip + dust lip), it is precision-molded to seal the interface between the front crankshaft and the gear housing/front cover. Prevents engine oil leakage and blocks dust/contaminants from entering the crankcase, ensuring the lubrication system’s integrity and reliable long-term engine operation.
