⚙️ Key Features

• 7.401 kg
• 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
