WESPC 3135M111 Piston Kit for Perkins 1104C-44T Diesel Engines

Application

WESPC 3135M111 piston kit is designed for Perkins 1104C-44T diesel engines, widely used in agricultural tractors, construction machinery, and medium-capacity generator sets. This standard bore kit is intended for in-frame overhaul or top-end rebuilds, restoring OEM compression, oil control, and fuel efficiency. The eutectic aluminum piston with anodized crown and reinforced ring grooves ensures durability under high thermal load and sustained heavy-duty operation.

Generator sets

pplied in Perkins-powered gensets from 60–150 kVA, especially those using 1104C-44T engines in prime or standby duty. The 3135M111 kit provides precise combustion sealing, stable output, and reduced oil consumption, supporting long service intervals in continuous or intermittent operation.

Industrial systems

Used in Massey Ferguson tractors, telehandlers, and construction loaders operating in dusty, high-load environments. The piston’s graphite-coated skirt reduces friction during break-in, while nitrided/chrome-faced rings maintain sealing integrity and resist wear over extended service life.
