Application:
WESPC 0E50255 rear crankshaft oil seal is designed for Perkins 400 series diesel engines, including models 403D-11, 403D-15, 403D-17, 404D-22, and 404D-22T. These compact engines are widely used in generator sets, agricultural machinery, construction equipment, and industrial systems. The seal is installed at the rear end of the crankshaft and serves to prevent engine oil leakage into the flywheel housing, maintain internal lubrication pressure, and protect transmission components from contamination. It ensures a secure seal between the crankshaft and engine block, supporting long-term reliability under continuous-duty and variable-load conditions.
Generator sets:
Commonly installed in 15–40 kVA diesel generator platforms powered by Perkins 400 series engines, including units from FG Wilson, Genmac, and other compact genset manufacturers. The WESPC 0E50255 oil seal maintains oil containment at the rear crankshaft interface, reducing the risk of seepage and supporting uninterrupted operation in both standby and prime power applications.
Construction machinery:
Suitable for compact equipment such as skid steer loaders, mini excavators, and small material handlers powered by Perkins 403D and 404D engines. The seal withstands vibration and thermal cycling, ensuring consistent lubrication and protecting engine components from oil contamination during rugged field operations.
Agricultural equipment:
Used in compact tractors and utility vehicles requiring reliable crankshaft sealing and extended service intervals. The WESPC 0E50255 oil seal supports efficient lubrication and reduced oil loss during extended field operations, contributing to engine cleanliness and reduced maintenance costs.
Industrial systems:
Applied in stationary diesel-driven systems such as hydraulic pumps, compressors, and mechanical drives where crankshaft sealing is essential for oil retention and thermal resistance. The seal’s elastomeric lip design ensures a tight interface under fluctuating pressure and temperature conditions, supporting 24/7 industrial performance.
Technical specifications:
Seal type: rear crankshaft lip seal Outer diameter: approx. 84.00 mm Inner diameter: approx. 65.00 mm Thickness: approx. 12.00 mm Material: high-temperature elastomer with reinforced sealing edge Temperature range: -40°C to +150°C Installation: press-fit configuration with precision sealing lip Surface finish: optimized for low-friction rotation and minimal wear Inspection: 100% leak-tested for sealing integrity and dimensional accuracy
Material & performance features:
Manufactured using high-grade elastomer compounds with enhanced thermal and chemical resistance. The sealing lip is precision-molded to maintain contact with the crankshaft surface under dynamic conditions, minimizing oil loss and contamination. Engineered to withstand vibration, rotational stress, and prolonged exposure to diesel engine environments, ensuring long-term durability and reduced maintenance frequency. Produced under ISO/TS16949-certified quality control standards.
Interchange part number:
0E50255; verified fitment for Perkins 403D and 404D series engines. Compatible with standard rebuild procedures across generator sets, construction machinery, agricultural equipment, and industrial systems.
