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.
