Removal Procedure
- Remove the engine front cover. Refer to
Engine Front Cover Replacement
.
- Remove the upper oil pan. Refer to
Upper Oil Pan Replacement
.
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.
- While holding the secondary oil pump shaft with a hex driver, remove the oil pump driven gear nut.
- Remove the oil pump driven gear.
- Remove the oil pump drive gear and crankshaft sensor reluctor. Do not damage the crankshaft reluctor teeth.
Important: Do not remove the reluctor from the oil pump drive gear unless replacing the reluctor or the oil pump drive gear. The reluctor is timed to the gear and once removed the correct timing will be lost.
- Remove the crankshaft reluctor to oil pump drive gear bolts.
- Inspect the crankshaft reluctor for the damage, bent teeth, being bent or warped.
- Inspect the oil pump drive gear for damaged or worn teeth.
- Inspect the oil pump drive gear crankshaft pin for wear.
- Inspect the groove of the crankshaft pin in the oil pump drive gear for wear.
- Replace any parts that are damaged or worn.
Installation Procedure
Important: The crankshaft reluctor and the oil pump drive gear are timed at the factory. In order to re-establish proper timing, install knock pins in the oil pump drive gear if the crankshaft reluctor was removed from the oil pump
drive gear. The knock pins are available through the parts department.
- Install the knock pins in the oil pump drive gear to a height of 4.5-5.5 mm (0.177-0.217 in)
- Install the crankshaft reluctor on the oil pump drive gear. Ensure the reluctor is aligned on the knock pins.
Notice: Refer to Fastener Notice in the Preface section.
- Install the crankshaft reluctor bolts.
Tighten
Tighten the bolts to 8 N·m (71 lb in).
Important: Do not damage the teeth on the crankshaft reluctor.
- Install the oil pump drive gear and reluctor to the crankshaft.
- Install the oil pump driven gear.
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.
- While holding the secondary oil pump shaft with a hex driver, install the oil pump driven gear nut.
Tighten
Tighten the nut to 100 N·m (74 lb ft).
