🔌 Function

The oil pump wheel is the geared drive component inside the engine's oil pump, converting drive from the engine into the pumping action that moves lubricating oil. Its condition directly determines the pump's ability to maintain correct oil pressure and flow throughout the engine.

⚠️ Common Signs of Failure

• Low or fluctuating engine oil pressure at idle and under load
• Whining, grinding or ticking noise traced to the oil pump area
• Worn, chipped or pitted gear teeth found on inspection
• Excessive backlash or end clearance between pump gears
• Metallic debris in the oil filter or sump indicating gear wear

🛠️ Service Notes

• Work clean: anything left in the pump or its housing goes straight into the oil galleries
• Inspect the wear faces, the housing and the mating gear for scoring, chipped or pitted teeth and metal pick-up, and renew the gears as a pair rather than putting a new wheel against a worn one
• Measure the running clearances between the wheel, its housing and the cover and compare them with the figures in the workshop manual for your engine — the pump only makes pressure while they are within limits
• Oil the wheel and housing on assembly and prime the pump as the manual directs so it picks up rather than running dry on first start
• Fit a new gasket or seal at the cover, then watch oil pressure on start-up and shut down at once if it does not come up
