Wespc CH11304 Rear Oil Seal for Perkins 2306 2506 Diesel Engine

Wespc CH11304 Rear Oil Seal for Perkins 2306 2506 Diesel Engine

Application:

WESPC CH11304 rear crankshaft oil seal is designed for Perkins 2300, 2500, and 2800 series 6-cylinder diesel engines, including models 2306TAG1, 2306TAG2, 2306TAG3, 2506TAG1, 2506TAG2, 2506TAG3, 2506TAG4, 2806TAG1, 2806TAG2, and 2806TAG3. These high-output engines are widely used in generator sets, construction machinery, agricultural equipment, and industrial power systems. The rear oil seal is installed at the flywheel end of the crankshaft to prevent engine oil leakage, maintain lubrication integrity, and protect the clutch housing and rear gear train from contamination.

Generator sets:

Commonly installed in 300–800 kVA diesel generator platforms powered by Perkins 2300, 2500, and 2800 series engines. The WESPC CH11304 oil seal ensures tight containment of engine oil at the rear crankshaft interface, supporting long-term operation and reducing maintenance frequency in commercial and industrial backup power systems.

Construction machinery:

Suitable for Caterpillar and other OEM equipment powered by Perkins 2506TAG and 2806TAG engines. The seal maintains a secure barrier between the crankcase and transmission components, preventing oil seepage and supporting consistent engine output in high-vibration environments.

Agricultural equipment:

Used in high-horsepower tractors and harvesters requiring stable crankshaft rotation and long service intervals. The oil seal supports efficient lubrication and reduced oil loss during extended field operations, contributing to engine cleanliness and reliability.

Industrial systems:

Applied in stationary hydraulic units, compressors, and mechanical drives where engine stability and oil system integrity are essential. The CH11304 seal supports continuous operation in demanding industrial environments, helping prevent oil leakage and maintain optimal lubrication performance.
