Removal Procedure
1. Remove the engine front cover. Refer to Engine Front Cover Replacement (See: Engine, Cooling and Exhaust/Engine/Timing
Components/Timing Cover/Service and Repair).
2. Remove the upper oil pan. Refer to Upper Oil Pan Replacement (See: Engine, Cooling and Exhaust/Engine/Engine Lubrication/Oil Pan/Service
and Repair/Upper Oil Pan Replacement).
Caution: Do not use an impact driver to remove or install the oil pump driven gear nut. Use of an impact driver may shear the oil pump drive
gear pin in the crankshaft.

Exhaust/Engine/Engine Lubrication/Oil Pump/Service and Repair).

the gear and once removed the correct timing will be lost.

5. Inspect the crankshaft reluctor for the damage, bent teeth, being bent or warped.
6. Inspect the oil pump drive gear for damaged or worn teeth.
