73. Timing Chain and Sprockets Installation
^ Tools Required- J 22102 Crankshaft Sprocket Installer
1. Properly install the crankshaft key into the crankshaft keyway, if removed.
IMPORTANT: If the sprocket(s) are being replaced, replace both sprockets to ensure that timing chain centerline alignment is maintained.
2. Install and align the keyway of the crankshaft sprocket with the crankshaft key.
3. Use the J 22102 in order to install the crankshaft sprocket.
4. Rotate the crankshaft until the crankshaft sprocket alignment mark is at the 12 o'clock position.
5. Rotate the camshaft until the camshaft alignment pin is in the 3 o'clock position.
NOTICE: Do not hammer the camshaft sprocket onto the camshaft. To do so may dislodge the rear camshaft plug and damage the camshaft.
NOTICE: The sprocket teeth must mesh with the timing chain in order to prevent damage to the camshaft retainer.
IMPORTANT: Ensure the camshaft alignment pin is engaged with the camshaft sprocket slot.
6. Place the timing chain on the camshaft sprocket with the camshaft sprocket alignment mark in the 6 o'clock position.
7. Install the camshaft sprocket and timing chain.
8. Look to ensure that the crankshaft sprocket is aligned at the 12 o'clock position and the camshaft sprocket is aligned at the 6 o'clock position.
NOTICE: Refer to Fastener Notice in Service Precautions.
9. Install camshaft sprocket bolts.
^ Tighten the camshaft sprocket bolts to 30 Nm (22 lb ft).
IMPORTANT: If the crankshaft sensor reluctor ring has been removed from the crankshaft, a new crankshaft sensor reluctor ring must be installed.
10. Install and align the keyway of the crankshaft position reluctor ring with the crankshaft key.
IMPORTANT: Ensure the J 22102 contacts the crankshaft balancer contact area of the crankshaft position reluctor ring in order to prevent bending or damage to the crankshaft position reluctor ring teeth.
IMPORTANT: It should be necessary to apply only light force in order to install the crankshaft position reluctor ring with the J 22102.
11. Use the J 22102 in order to install the crankshaft position reluctor ring onto the crankshaft until the ring is completely seated against the crankshaft sprocket.
