WESPC 1817867C93 Rear Oil Seal for Perkins 1300 Series Diesel Engine Crankshaft

WESPC 1817867C93 Rear Oil Seal for Perkins 1300 Series Diesel Engine Crankshaft

Application:

WESPC 1817867C93 rear crankshaft seal kit is designed for Navistar International DT466, DT466E, DT530, and DT530E diesel engines produced between 1993 and 2003. These engines are widely used in medium-duty trucks, school buses, generator sets, and industrial equipment. The seal kit is installed at the rear end of the crankshaft and plays a critical role in preventing oil leakage from the engine block into the flywheel housing. It ensures proper lubrication containment, protects transmission components from contamination, and supports long-term engine reliability under continuous-duty and high-load conditions.

Medium-duty trucks:

Commonly used in International 4000 series vehicles such as 4300 and 4400 models powered by DT466E engines. The WESPC 1817867C93 seal kit maintains oil integrity at the rear crankshaft interface, reducing the risk of seepage and supporting consistent performance during long-haul and vocational operations.

School buses: Installed in IC Bus platforms equipped with DT466E and DT530E engines. The seal kit ensures clean engine operation and protects clutch assemblies from oil contamination, contributing to reduced maintenance and extended service intervals.

Generator sets:

Applied in stationary diesel generator platforms powered by DT-series engines, typically ranging from 100–200 kVA. The seal kit supports uninterrupted operation by maintaining crankcase pressure and preventing rear-end oil leakage that could compromise generator reliability.

Industrial systems:

Used in diesel-powered hydraulic units, compressors, and mechanical drives where crankshaft sealing is essential for oil retention and thermal resistance. The kit’s multi-component design ensures a secure interface under fluctuating pressure and temperature conditions, supporting 24/7 industrial performance.
