WESPC 198636170 Rear End Oil Seal for Perkins 404D 15 404C 22 404F 22 Engines

Application:

WESPC 198636170 rear end oil seal is designed specifically for Perkins 404 series engines, including models like 404D-15, 404C-22, and 404F-22, with verified compatibility across these engine variants. The Perkins 404 series engines are widely utilized in agricultural tractors, construction machinery, generator sets, and industrial power systems, where reliable oil sealing is critical to prevent leaks and maintain optimal lubrication. As a rear end oil seal, it functions to seal the rear of the engine crankshaft, blocking oil from escaping the crankcase and preventing contaminants from entering, thus ensuring consistent engine performance and extending the service life of critical components.

Generator sets:

Commonly integrated into 30–75 kVA diesel generator platforms powered by Perkins 404 series engines, the WESPC 198636170 rear end oil seal maintains a tight seal during continuous operation. This is essential for generator sets in commercial, industrial, and backup power applications, where oil leaks could lead to reduced lubrication, increased wear on moving parts, or unexpected shutdowns—making seal integrity vital for reliable runtime and uninterrupted power supply.

Construction machinery:

Suitable for equipment such as compact excavators, skid steer loaders, and backhoe loaders powered by Perkins 404 series engines. In construction environments, where machinery operates under high vibration, varying loads, and exposure to dust and debris, the rear end oil seal withstands these conditions to prevent oil leaks. This ensures proper lubrication of the crankshaft and related components, reducing maintenance downtime and supporting consistent performance on job sites.

Agricultural equipment:

Applied in tractors, combine harvesters, and irrigation pumps utilizing Perkins 404 series engines. Agricultural operations often involve extended use in rugged, dusty, or muddy terrain, and the WESPC 198636170 rear end oil seal provides a robust barrier against oil loss and contamination. It supports reliable engine operation during planting, harvesting, and other seasonal tasks, where equipment uptime directly impacts productivity.

Industrial systems:

Used in stationary equipment such as water pumps, air compressors, and material handling machinery powered by Perkins 404 series engines. In industrial settings, where equipment operates continuously under heavy loads, the rear end oil seal maintains seal integrity to prevent oil leaks, ensuring stable engine performance and reducing the need for unscheduled maintenance—key for maintaining production efficiency in factories, warehouses, and processing facilities.

Technical specifications:
WESPC 198636170 is a rear end oil seal compatible with Perkins 404 series engines (404D-15, 404C-22, 404F-22).
