Application
WESPC 3861A027 piston oil cooling jet for Perkins 1004-series diesel engines. Commonly used in FG Wilson generator sets, agricultural tractors, and construction machinery. Installed beneath the piston to spray pressurized oil onto the crown underside, effectively dissipating heat and preventing thermal fatigue during high-load operation.
Generator sets
Suitable for Perkins-powered gensets rated 80–150 kVA. Enhances piston longevity and combustion stability by maintaining optimal operating temperatures during continuous duty cycles.
Industrial & agricultural equipment
Applied in Massey Ferguson tractors, JCB loaders, and other OEM platforms using Perkins 1004.40 / 1004.40T engines. Supports lubrication system performance and protects pistons from overheating under sustained mechanical stress.
