Oil Pump Shaft & Gear Assembly — Hardened Drive Gear, Precision-Machined Shaft SKU: QT3329

This oil pump shaft and gear assembly restores a positive, slip-free drive to the oil pump so pressure and flow stay consistent. It’s a smart replacement when the original gear shows wear, noise, or uneven pump engagement.

Built for long service, the hardened gear teeth and precision-machined shaft track true through heat and vibration, helping protect bearings and reduce cavitation risk. A practical choice during bottom-end work or a pump swap.

• Hardened steel drive gear for wear resistance and long life
• Precision-machined shaft for smooth, reliable pump engagement
• Stable pump drive to support steady oil pressure at working RPM
• Low-noise tooth profile helps maintain quiet, consistent operation

Installation Tip: Pre-lube components with clean engine oil, align the gear mesh carefully, and torque retainers to spec; prime the lubrication system and verify warm idle pressure after start-up.

A straightforward, dependable assembly that helps keep the lubrication system stable and your equipment running smoothly.
