WESPC U5PR0059 Piston Ring Kit for Perkins 1004.4 1004.4T Series

Application

WESPC U5PR0059 piston ring 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 kit restores combustion sealing and oil control in 4-cylinder platforms operating under medium to high load conditions. Its multi-ring configuration supports Tier 2 emission compliance and long service intervals in both field and industrial environments.

Generator sets

Applied in Perkins-powered generator sets ranging from 80–150 kVA, especially those equipped with 1004.4T engines. The U5PR0059 ring kit ensures consistent compression, reduced blow-by, and stable output under standby and prime power modes.

Industrial systems Used in Massey Ferguson tractors, loaders, and agricultural machinery requiring high torque and thermal resilience. Its surface-treated rings resist wear, scuffing, and fatigue, supporting long operational cycles under variable load and harsh field conditions.
