Timing Chain and Sprockets Installation

- Tools Required
- J 5590 Installer





1. Install the crankshaft balancer woodruff keys into the crankshaft keyway.





2. Align the keyway of the crankshaft sprocket with the crankshaft balancer woodruff key.

Caution: Refer to Safety Glasses Caution in Service Precautions.

3. Use the J 5590 in order to install the crankshaft sprocket.
4. Rotate the crankshaft until the crankshaft sprocket alignment mark is in the 12 o'clock position.





5. Install the camshaft sprocket and the camshaft timing chain. Install the camshaft sprocket with the alignment mark in the 6 o'clock position.





Notice: Do not use tools to force the camshaft sprocket onto the camshaft. The camshaft sprocket is a slip fit onto the camshaft and does not require tools to install. Using force against the camshaft can cause component damage and cause the expansion plug at the rear of the block to move out of position. The expansion plug out of position can leak engine oil or fall out. A missing or leaking expansion plug at the rear of the camshaft bearings can cause a loss of oil and oil pressure leading to extensive engine damage.

6. Rotate the camshaft until the camshaft and crankshaft sprocket alignment marks are in the proper position.

Notice: Refer to Fastener Notice in Service Precautions.

7. Install camshaft sprocket bolts.
- Tighten the camshaft sprocket bolts to 25 Nm (18 ft. lbs.).





Important: Align the keyway on the crankshaft position sensor reluctor ring with the crankshaft balancer woodruff key in the crankshaft. Install the crankshaft position sensor reluctor ring onto the crankshaft until completely seated against the crankshaft sprocket.

8. Install the crankshaft position sensor reluctor ring.
8.1. Align the keyway on the crankshaft position sensor reluctor ring with the crankshaft balancer woodruff key in the crankshaft.
