E320C Excavator Engine Oil Pump Assembly with Oil Cooler Housing for 3066 S6K Diesel Engine Spare Parts

The E320C Excavator Engine Oil Pump Assembly is a replacement diesel engine lubrication system component offered for compatible 3066 and S6K engine configurations.

The engine oil pump plays an important role in circulating lubricating oil through the engine's internal lubrication passages, helping supply oil to crankshaft bearings, connecting rod bearings, camshaft components, and other designated moving parts.

A correctly matched and properly functioning oil pump supports the engine's specified lubrication requirements and helps maintain reliable operation under demanding construction machinery working conditions.

The pictured assembly features a yellow cast-metal housing, machined mounting surfaces, multiple bolt holes, internal passage openings, and visible intermeshing drive gears.

Its integrated housing design includes several mounting and fluid connection interfaces intended for installation in the corresponding engine assembly.

JISION supplies excavator engine oil pumps, diesel engine lubrication components, engine housings, hydraulic parts, and construction machinery replacement parts to equipment owners, repair workshops, and international spare parts distributors.
