1556097 Oil Pump Wheel | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta oil pump wheel is an engine-lubrication and piston-cooling service component used in the engine oil-pump drive. It is manufactured to the original Volvo Penta dimensions and interface requirements so calibrated oil flow and pressure are maintained through the lubricating circuit. Replacement oil-pump gear; use with repair kit 276871. In service, it drives the oil-pump mechanism so lubricating oil is circulated through the engine. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556097 against the installed assembly before ordering.

🔌 Function

The oil pump wheel transfers drive from the engine to the lubricating oil pump so that pressurised oil is circulated to bearings and moving components. Correct engagement of this wheel is essential for maintaining oil pressure throughout the engine.

⚠️ Common Signs of Failure

• Low or fluctuating oil pressure at the gauge or warning lamp
• Worn, chipped or broken gear teeth found on inspection
• Whining, grinding or rattling noise from the front of the engine
• Metal debris or gear material in the oil pan or filter
• Loss of oil pump drive resulting in no pressure build-up at start-up

🛠️ 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
