WESPC 115017491B Piston Kit for Perkins 404C-22 404D-22 404D-22T Diesel Engines

Application

WESPC 115017491B piston kit is designed for Perkins 404C-22, 404D-22, and 404D-22T diesel engines, commonly used in compact agricultural tractors, skid steer loaders, telehandlers, and small-to-medium generator sets. This oversize +0.50 mm kit is intended for engines undergoing cylinder re-boring during overhaul, restoring compression, oil control, and fuel efficiency to OEM standards. The eutectic aluminum piston with anodized crown and reinforced ring grooves ensures durability under high thermal and mechanical loads.

Generator sets

Applied in Perkins-powered gensets from 20–60 kVA, particularly those using 404 series engines in prime or standby duty. The 115017491B kit provides precise combustion sealing after reconditioning, maintaining rated output and reducing oil consumption in continuous or intermittent operation.

Industrial systems

Used in compact construction machinery, forklifts, and agricultural equipment operating in dusty, high-load environments. The piston’s graphite-coated skirt reduces friction during break-in, while nitrided/chrome-faced rings resist wear and maintain sealing integrity over extended service intervals.
