WESPC U5PR0058 Piston Ring Kit for Perkins 1004.4 1004.4T Diesel Engines

Application

WESPC U5PR0058 piston ring kit is designed for Perkins 1004.4 and 1004.4T diesel engines. This kit is used in mid-size industrial platforms such as agricultural machinery, construction equipment, and medium-duty generator sets. Its multi-ring configuration with nitrided and chrome finishes supports efficient combustion, reduced oil consumption, and extended service intervals under Tier 2 compliance.

Generator sets

Applied in Perkins-powered generator sets ranging from 80–150 kVA, especially those equipped with 1004.4T engines. The U5PR0058 piston ring kit ensures reliable compression sealing and oil control, contributing to stable output and fuel efficiency in both standby and continuous-duty gensets.

Industrial systems

Used in Massey Ferguson tractors, loaders, and agricultural equipment operating under high torque and thermal load conditions. Its steel alloy rings with precision-machined profiles resist wear, scuffing, and fatigue, supporting durability in heavy-duty, four-cylinder diesel platforms.
