WESPC T426417 U5PR0062 Piston Kits Perkins 1104D-44T 1106 Series

WESPC T426417 U5PR0062 Piston Kits Perkins 1104D-44T 1106 Series

Application

WESPC T426417 & U5PR0062 piston kits are designed for Perkins 1104D-44T and 1106 series diesel engines, widely used in Tier 2/3 electronic platforms across agricultural, construction, and generator applications. These kits restore combustion sealing and oil control in high-load environments, supporting emission compliance and long service intervals. Their reinforced alloy pistons and multi-ring configurations are optimized for VK/NL/NM builds, including Massey Ferguson tractors and FG Wilson gensets.

Generator sets

Applied in Perkins-powered generator sets ranging from 100–250 kVA, especially those equipped with 1104D-44T and 1106C-E60TA engines. The T426417 and U5PR0062 kits ensure consistent compression, reduced blow-by, and stable output under both standby and prime power conditions.

Industrial systems

Used in wheeled tractors, loaders, and agricultural machinery requiring high torque and thermal resilience. Their surface-treated pistons and precision-machined rings resist wear, scuffing, and fatigue, supporting long operational cycles under variable load and harsh field conditions.
