-   Lubricating and Oil System group
-   Pumping element inside the oil pump

## 🔌 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
