⚙️ Key Features

• 0.321 kg
• 37 applications across six engine series
• Oil pump gear wheel rather than a drive gear

🔌 Function

Meshes with its partner gear inside the oil pump to draw oil from the sump and deliver it under pressure.

⚠️ Common Signs of Failure

• Oil pressure low at idle and slow to come up when cold
• Tooth faces pitted, chipped or worn hollow
• Scoring on the wheel end faces from debris in the oil
• Whine from the front of the engine that follows engine speed
• Excessive backlash or end clearance measured on strip-down

🛠️ Service Notes

• Gear 422047 is the heavier Lubricating and Oil System gear supplied within the overhaul kit, so check which the pump takes before ordering
• Measure backlash and end float against the manual figures rather than reusing on appearance
• Find where the debris came from before fitting a new wheel, or it will pick up again
