Removal Procedure

Notice: 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.
3. While holding the secondary oil pump shaft with a hex driver, remove the oil pump driven gear nut.
4. Remove the oil pump driven gear.
Important: DO NOT remove the reluctor from the oil pump drive gear. The reluctor is timed to the gear and once removed the correct
timing will be lost.
