WESPC CH11994 Piston Kit for Perkins 1004.4 1004.4T Diesel Engines

Application

WESPC CH11994 piston kit is designed for Perkins 1004.4 and 1004.4T diesel engines. Commonly used in agricultural tractors, construction machinery, and mid-range generator sets, this standard bore kit restores compression, oil control, and combustion efficiency during overhaul. The anodized crown and reinforced ring grooves ensure durability under high-load operation.

Generator sets

Suitable for Perkins gensets rated 80–150 kVA. Provides stable combustion sealing and reduced oil consumption in both prime and standby applications.

Industrial systems

Used in Massey Ferguson tractors and industrial loaders operating in dusty, high-torque environments. Graphite-coated skirt reduces friction; nitrided and chrome-faced rings maintain long-term sealing performance.
