Application
WESPC 115017491 piston kit is designed for Perkins 400 series diesel engines, including 403C-15, 403D-15, 404C-22, and 404D-22 builds. This kit is used in compact industrial platforms such as small generators, agricultural equipment, and construction machinery. Its lightweight design and surface treatments support efficient combustion, reduced oil consumption, and long service intervals under Tier 2/3 compliance.
Generator sets
Applied in Perkins-powered generator sets ranging from 10–40 kVA, especially those equipped with 403D and 404D engines. The 115017491 piston kit ensures reliable compression sealing and oil control, contributing to stable output and fuel efficiency in both standby and continuous-duty gensets.
Industrial systems
Used in compact tractors, skid-steer loaders, and light construction equipment operating under intermittent load cycles. Its eutectic aluminum alloy piston and treated ring grooves resist scuffing and thermal fatigue, supporting durability in high-speed, small-displacement diesel platforms.
