🔌 Function

⚠️ Common Signs of Failure

• Oil pressure low or fluctuating, worst hot and at idle
• Oil pressure alarm or warning lamp coming on
• Whine or rattle from the front of the engine
• Gear faces and pump body scored or polished on strip-down
• Excessive clearance between the gears and the housing

🛠️ Service Notes

• Renew the pickup screen and its gasket at the same time, and prime the pump with clean oil before the first start
• Establish why the old pump failed before fitting this one - debris from a bearing failure will destroy a new pump quickly
