- J 5590 Pinion Bearing Race Installer - Rear





1. Install the crankshaft balancer key into the crankshaft keyway. The crankshaft balancer key should be parallel to the crankshaft or with a slight incline.





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

3. Caution: Refer to Safety Glasses Caution in Service Precautions.

Use the J 5590 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. Important: Install the camshaft sprocket with the alignment mark at the 6 o'clock position.

Install the camshaft sprocket and the camshaft timing chain.





6. Look to ensure that the crankshaft sprocket is aligned at the 12 o'clock position and camshaft sprocket is aligned at the 6 o'clock position.





7. Notice: Refer to Fastener Notice in Service Precautions.

Important: Do not use a hammer to install the camshaft sprocket onto the camshaft. To do so may dislodge the expansion cup plug, camshaft rear bearing hole.

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





8. Install the timing chain tensioner bracket and bolt (227 and 228).
^ Tighten the timing chain tensioner bracket bolt to 12 Nm (106 inch lbs.).

9. Important: The timing chain tensioner shoe snaps onto the tensioner bracket. Ensure that the shoe is fully seated before proceeding.

Install the timing chain tensioner shoe (229) using an upwards motion.





10. Install the crankshaft position sensor reluctor ring.
