WESPC 4115P013 Piston Kit for Perkins 1103 1104 Diesel Engines

WESPC 4115P013 Piston Kit for Perkins 1103 1104 Diesel Engines

Application

WESPC 4115P013 piston kit is designed for Perkins 1103 and 1104 series diesel engines, including 1103C-33, 1103D-33, 1104C-44, and 1104D-44 builds. This oversize 0.040" (1.00 mm) bore kit is used in agricultural tractors, construction machinery, and generator sets requiring in-frame overhaul or cylinder reconditioning. The eutectic aluminum piston with treated ring grooves ensures high wear resistance, stable compression, and extended service life under heavy-duty operation.

Generator sets

Applied in Perkins-powered gensets from 30–100 kVA, especially those using 1103/1104 series engines in prime or standby duty. The 4115P013 kit restores combustion sealing and oil control in overhauled engines, improving fuel efficiency and maintaining rated output after cylinder re-boring.

Industrial systems

Used in Massey Ferguson tractors, telehandlers, and industrial loaders operating under high torque and variable load conditions. The piston’s anodized crown and graphite-coated skirt reduce scuffing during break-in, while nitrided/chrome-faced rings maintain sealing in dusty or high-temperature environments.
