NOTICE: Do not loosen or remove the bolt without first installing the special tools as instructed inthis procedure. The pulley and the are not keyed to the crankshaft. Thecrankshaft, the and the pulley are fitted together by friction, using diamond washers betweenthe flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt isloosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and

must be locked in place by the special service tools, otherwise severe engine damage can occur.

Installation

1. Install the timing chain guide and the bolts. : 89 lb.in (10 Nm)Torque

Install the timing chain. Install the timing chain tensioner arm.


NOTE: If equipped with aluminum timing chain tensioner.

NOTE: If the timing chain tensioner plunger is not pinned in the compressed position, follow the next step.

2. Reset the timing chain tensioner. 1. Position the timing chain tensioner in a soft-jawed vise. 2. Spread the ends of the ratchet wire clip apart. 3. Using the soft-jawed vise, compress the plunger to the reset position. 4. Install a locking pin in the 2 holes of the timing chain tensioner body to hold the plunger in place.


3. NOTE: If equipped with aluminum timing chain tensioner.

NOTE: Do not remove the locking pin until the tensioner bolts are tightened.
