Crankshaft Position Timing Ring: Service and Repair

Crankshaft Reluctor and Oil Pump Drive Gear Replacement

Removal Procedure





1. Remove the engine front cover.
2. Remove the oil pump driven gear nut.
3. Remove the oil pump driven gear.





4. Remove the oil pump drive gear and crankshaft sensor reluctor assembly. Do not damage the crankshaft reluctor teeth.





Important: Do not remove the crankshaft reluctor from the oil pump drive gear unless replacing the crankshaft reluctor or the oil pump drive gear. The crankshaft reluctor is timed to the gear and once removed the correct timing is lost.

5. Remove the bolts retaining the crankshaft reluctor to oil pump drive gear.
6. Inspect the crankshaft reluctor for damaged or bent teeth.
7. Inspect the crankshaft reluctor for being bent or warped.
8. Inspect the oil pump drive gear for damaged or worn teeth.
9. Inspect the oil pump drive gear crankshaft pin for wear.
10. Inspect the groove for the crankshaft pin in the oil pump drive gear for wear.
11. 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.

1. Install the knock pins in the oil pump drive gear to a height of 4.5 - 5.5 mm (0.177 - 0.217 inch)





Notice: Refer to Fastener Notice in Service Precautions.

2. Install the crankshaft reluctor on the oil pump drive gear. Ensure the reluctor is aligned on the knock pins.
3. Install the crankshaft reluctor bolts.
- Tighten the crankshaft reluctor bolts to 8 Nm (71 inch lbs.).





Important: Do not damage the teeth on the crankshaft reluctor assembly.

4. Install the oil pump drive gear and reluctor assembly to the crankshaft.





5. Install the oil pump driven gear.
6. Install the oil pump driven gear nut.
- Tighten the oil pump driven gear nut to 100 Nm (74 ft. lbs.).
7. Install the engine front cover.
