Product Specification

WESPC 198636090 Front Oil Seal for Perkins 400 Series Diesel Crankshaft Part

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.
