WESPC 1817867C92 Rear Oil Seal For Perkins 1300 Series Diesel Crankshaft Part

WESPC 1817867C92 Rear Oil Seal for Perkins 1300 Series Diesel Crankshaft Part

Application:

WESPC 1817867C92 rear crankshaft oil seal is designed for Navistar International DT466E and DT530E diesel engines, including serial ranges from 1993 to 2003. These engines are widely used in medium-duty trucks, school buses, and industrial power systems. The seal is installed at the rear end of the crankshaft, where it plays a critical role in preventing engine oil leakage, maintaining internal lubrication pressure, and protecting the flywheel housing and rear gear train from contamination. This component is essential for preserving engine cleanliness and mechanical integrity under continuous-duty and high-load conditions.

Generator sets:

Used in stationary diesel generator platforms powered by DT466E engines, typically ranging from 100–200 kVA. The WESPC 1817867C92 oil seal ensures tight containment of engine oil at the rear crankshaft interface, supporting uninterrupted operation and reducing service frequency in commercial and industrial backup systems. Its combined sealing structure includes a wear ring and dust seal, enhancing long-term durability and leak prevention.

Construction machinery:

Suitable for industrial-grade equipment such as compact loaders, hydraulic units, and material handlers powered by DT530E engines. The seal maintains lubrication integrity under high-vibration and high-temperature conditions, preventing oil seepage and protecting critical engine components during demanding field operations. Its multi-component design supports extended service intervals and consistent sealing performance.

Agricultural equipment:

Applied in diesel-powered tractors and harvesters using DT-series engines, where crankshaft sealing is essential for oil retention and thermal resistance. The WESPC 1817867C92 oil seal supports efficient lubrication and reduced oil loss during extended field operations, contributing to engine reliability and reduced maintenance costs.

Industrial systems:

Integrated into stationary diesel-driven systems such as compressors, mechanical drives, and hydraulic power units where crankshaft sealing is critical for system integrity. The seal’s press-fit configuration and reinforced elastomeric lip ensure a secure interface under fluctuating pressure and temperature conditions, supporting 24/7 industrial performance.

Technical specifications:

Seal type: rear crankshaft combined seal Includes: primary oil seal, dust seal, wear ring Material: high-temperature elastomer and hardened steel ring Outer diameter: approx. 127.00 mm Inner diameter: approx. 100.00 mm Thickness: approx. 15.00 mm Temperature range: -40°C to +150°C Installation: press-fit with wear ring alignment 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 and precision-machined steel components with enhanced thermal and chemical resistance. The sealing lip is molded to maintain contact with the crankshaft surface under dynamic conditions, minimizing oil loss and contamination. The wear ring provides a hardened sealing surface to extend service life. 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.
