WESPC 115017620 Piston Kit for Perkins 402D-05 402D-07 Diesel Engines

Application

WESPC 115017620 piston kit is designed for Perkins 402D-05 and 402D-07 diesel engines, widely used in compact agricultural tractors, mini excavators, skid steer loaders, and small 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 frequent start-stop cycles.

Generator sets

Applied in Perkins-powered gensets from 8–20 kVA, especially those using 402D series engines in standby or continuous duty. The 115017620 kit provides precise combustion sealing, stable output, and reduced oil consumption, supporting long service intervals in light-to-medium load applications.

Industrial systems

Used in compact construction machinery, turf equipment, and small industrial pumps operating in dusty or high-vibration 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.
