🔌 Function

Forms the pumping element inside the oil pump, its teeth carrying oil round the body to build delivery pressure.

⚠️ Common Signs of Failure

• Oil pressure low, slow to build or dropping when hot
• Whine or growl from the pump drive
• Tooth flanks pitted, chipped or scored
• End and tip clearances outside specification when measured
• Metallic glitter in the oil and on the filter element

🛠️ Service Notes

• Measure the pump body and end clearances as well, since a worn body will not recover pressure with a new wheel
• Find the source of any debris in the oil before reassembly, and prime the pump before the first start
