🔹Product Overview

This engine oil pump Part No.4941148 is the core lubrication component specially designed for cumm-ins QSB3.3, ISB, 4BT diesel engines. It pressurizes and circulates engine oil to every friction part of the engine, including crankshaft, connecting rods, camshaft and valve train. Sufficient oil pressure reduces metal‑to‑metal friction, takes away excess heat and prevents premature wear, seizing or engine burnout. Our aftermarket oil pump is manufactured strictly according to OEM specifications, using high‑strength cast‑iron material, with stable oil‑supply pressure, low noise and outstanding wear‑resistance. It is a reliable spare part for engine maintenance and overhaul for construction and industrial equipment.
