WESPC 4115P011 10000-02835 Piston Kits for Perkins 1103 1104 Series

Application

WESPC 4115P011 & 10000-02835 piston kits are designed for Perkins 1103 and 1104 series diesel engines, widely used in Tier 2 agricultural tractors, construction machinery, and mid-range generator sets. These kits restore combustion sealing and oil control in 3- and 4-cylinder platforms operating under medium to high load conditions. Their alloy pistons and multi-ring configurations support emission compliance and long service intervals in Massey Ferguson, FG Wilson, and other OEM-integrated systems.

Generator sets

Applied in Perkins-powered generator sets ranging from 80–150 kVA, especially those equipped with 1103A-33T and 1104C-44T engines. The 4115P011 and 10000-02835 kits ensure consistent compression, reduced blow-by, and stable output under standby and prime power modes.

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.
