Notice: Perform TDC Offset Recovery procedure if the timing chain, timing gears, engine front cover, crankshaft position sensor, crankshaft or other components affecting the timing are replaced.

1. Disconnect the battery negative cables from the batteries. Refer to Battery Cable Replacement in Engine Electrical.
2. Remove the water pump from the engine front cover. Refer to Water Pump Replacement in Engine Cooling.
3. Remove the fuel injection pump drive gear. Refer to Fuel Injection Pump Replacement in Engine Controls-6.5L.
4. Remove the engine front cover from the engine block. Refer to Engine Front Cover Replacement .
5. Remove the bolt from the timing chain sprocket to the camshaft.



6. Remove the fuel injection pump drive gear from the timing chain sprocket.



7. Remove the timing chain and sprocket from the camshaft.



8. Remove the sprocket from the crankshaft.

1. Install the crankshaft sprocket to the crankshaft.



2. Align the timing marks on the gears.



3. Install the camshaft sprocket with the timing chain.



4. Install the fuel injection drive gear to the camshaft.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
