-   1 recorded application on TAD series engines
-   Supersedes 17438679
-   Lubricating and Oil System group

## 🔌 Function

Draws oil from the sump and delivers it under pressure to the galleries, keeping every bearing and running surface fed while the engine turns.

## ⚠️ Common Signs of Failure

-   Oil pressure low, or the warning light flickering at idle
-   Pressure slow to come up on a cold start
-   Whine or rumble from the front of the engine that tracks with speed
-   Rotor or housing found scored, with increased clearances
-   Bearing damage found elsewhere from oil starvation

## 🛠️ Service Notes

-   Confirm the pressure reading with a gauge before condemning the pump - a sticking relief valve or a worn bearing gives the same symptom
-   Prime the pump and renew the pick-up strainer and filter when fitting, and flush the system if the old pump has broken up
-   At 7.4 kg this is a substantial assembly, so plan the lift and support it while the fasteners are started
