WESPC 050209083 Rear Oil Seal for Perkins 404D-22 22T Diesel Crankshaft Part

WESPC 050209083 Rear Oil Seal for Perkins 404D-22 22T Diesel Crankshaft Part

Application:

WESPC 050209083 rear crankshaft oil seal is designed for Perkins 400 series 4-cylinder diesel engines, specifically models 404D-22 and 404D-22T. These engines are commonly used in compact tractors, skid steer loaders, lawn and garden equipment, and small generator sets. The rear oil seal plays a critical role in maintaining engine lubrication integrity by preventing oil leakage at the rear end of the crankshaft, where rotational motion meets the stationary engine block. This seal ensures proper containment of engine oil under high-speed and high-temperature conditions, supporting long-term engine reliability and minimizing maintenance intervals.

Generator sets:

Installed in compact diesel generator platforms ranging from 15 to 30 kVA, powered by Perkins 404D-22 engines. The WESPC 050209083 rear oil seal helps maintain consistent oil pressure and prevents rear-end leakage during continuous operation, contributing to stable performance in residential, commercial, and light industrial backup power systems.

Construction machinery:

Suitable for New Holland and JCB skid steer loaders and mini excavators equipped with Perkins 404D-22T engines. The rear oil seal withstands high vibration and thermal cycling, ensuring crankcase sealing integrity in off-road and heavy-duty environments. It supports reliable operation in compact construction equipment where space constraints demand precise sealing solutions.

Agricultural equipment:

Used in Ford and New Holland compact tractors such as the T1510, T1520, TC35, TC45, and Boomer series. The WESPC 050209083 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 stationary pumps, small compressors, and mechanical drives powered by Perkins 404D-22 engines. The rear oil seal maintains lubrication system integrity under continuous load and rotational stress, supporting stable engine operation in compact industrial installations.
