2.1.	The number one cylinder is at top dead center (TDC) of the compression stroke.

2.2.	The timing marks on both sprockets line up.




3. Remove the camshaft sprocket bolts.
4. Remove the camshaft sprocket and the camshaft timing chain.



5. Use the J 5825-A in order to remove the crankshaft sprocket.

Tools Required

J 5590 Installer

1. Install the woodruff key (crankshaft balancer) into the crankshaft, if removed.

Caution: Wear safety glasses in order to avoid eye damage.




2. Align the keyway of the crankshaft sprocket with the woodruff key (crankshaft balancer).
3. Use the J 5590 and a hammer in order to install the crankshaft sprocket.
4. Ensure that the number 1 piston is still at TDC of the compression stroke.
5. Align the timing marks on both sprockets.

Ensure that the crankshaft sprocket alignment mark is in the 12 o'clock position.




6. Install the camshaft sprocket and the timing chain.

The camshaft sprocket alignment mark must be in the 6 o'clock position.

7. Ensure that you align the camshaft sprocket and the crankshaft sprocket alignment marks.

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.

8. Install the camshaft sprocket bolts.

Tighten
Tighten the bolts to 25 N·m (18 lb ft).




9. Install the crankshaft position reluctor ring and the engine front cover. Refer to Crankshaft Position Sensor Reluctor Ring Replacement .
