The 8976173080 timing gear case oil seal is an OEM replacement component designed for Isuzu 6WG1 6WF1 6WA1 series diesel engines. It seals the front crankshaft outlet at the timing gear case to prevent engine oil leakage. The seal features a rubber sealing lip bonded to a metal case, engineered to withstand diesel engine operating temperatures and crankshaft rotational speeds. This part serves as a direct replacement for Isuzu part numbers 8-97617308-0, 1096255561, and 1-09625556-1. It is widely used in construction machinery equipped with these Isuzu engines, including John Deere 600C 800C 450DLC 650DLC 850DLC 670GLC 470GLC 870GLC excavators, Hitachi ZX450 ZX460LCH ZX470 ZX480MT ZX500LC ZX600 ZX650H ZX870 excavators and LX300-7 wheel loader, as well as Isuzu CXZ51K CXZ51 CYZ51 trucks.
