Application:
WESPC CH11379 rear crankshaft oil seal, interchangeable with part number 142-5867, is designed for Caterpillar 3054 and Perkins 1004 series 4-cylinder diesel engines. These engines are widely used in compact construction machinery, agricultural tractors, generator sets, and industrial systems. The rear crankshaft seal is installed at the flywheel end of the engine, preventing engine oil from leaking into the bellhousing or clutch housing. It plays a critical role in maintaining crankcase pressure and protecting transmission components from oil contamination during high-speed operation and thermal cycling.
Generator sets:
Commonly installed in 80–120 kVA diesel generator platforms powered by Perkins 1004-4 engines. The WESPC CH11379 rear oil seal ensures consistent oil retention and crankshaft sealing during continuous operation, contributing to stable performance and reduced maintenance in commercial and industrial backup power systems.
Construction machinery:
Suitable for Caterpillar skid steers, compact loaders, and small excavators equipped with 3054 engines. The rear seal withstands vibration, dust ingress, and thermal expansion in off-road environments, supporting reliable engine operation in demanding construction applications.
Agricultural equipment:
Used in Massey Ferguson tractors such as the 390, 398, and 399 models powered by Perkins 1004-4 engines. The WESPC CH11379 seal ensures effective oil containment during extended field operations, reducing the risk of clutch contamination and crankshaft wear. It contributes to longer service intervals and improved engine durability in agricultural applications.
Industrial systems: Applied in stationary pumps, compressors, and mechanical drives requiring high engine stability and rotational precision. The rear oil seal maintains lubrication system integrity under continuous load and rotational stress, supporting stable engine operation in demanding industrial installations.
