Application:
WESPC 198636090 front crankshaft oil seal is designed for Perkins
400 series 2-, 3-, and 4-cylinder diesel engines, including models
402D-05, 402F-05, 403A-11, 403D-07, 403D-11, and 404D-15. These
engines are widely used in compact construction machinery,
agricultural equipment, generator sets, and small industrial
systems. The front oil seal is a critical component that prevents
engine oil from leaking at the front end of the crankshaft, where
the pulley or timing gear is mounted. It ensures proper lubrication
containment and protects the engine from external contaminants,
contributing to long-term reliability and reduced maintenance.
Generator sets:
Commonly installed in 10–30 kVA diesel generator platforms powered
by Perkins 400 series engines. The WESPC 198636090 front oil seal
maintains oil pressure and sealing integrity during continuous
operation, helping prevent front-end leakage and ensuring stable
performance in residential and commercial backup power systems.
Construction machinery:
Suitable for compact excavators, skid steer loaders, and aerial
work platforms equipped with Perkins 403D and 404D engines. The
front oil seal withstands high vibration and thermal cycling,
ensuring crankcase sealing integrity in demanding off-road
environments. It supports reliable operation in compact
construction equipment where precise sealing is essential.
Agricultural equipment:
Used in compact tractors and utility vehicles such as New Holland
Boomer series and Massey Ferguson models powered by Perkins 400
series engines. The WESPC 198636090 seal ensures effective oil
containment during extended field operations, reducing the risk of
oil contamination and crankshaft wear. It contributes to longer
service intervals and improved engine longevity in agricultural
settings.
Industrial systems: Applied in small compressors, pumps, and
mechanical drives requiring compact diesel power. The front oil
seal maintains lubrication system integrity under continuous load
and rotational stress, supporting stable engine operation in light
industrial installations.
