Timing Chain & Sprockets - Installation

INSTALLATION





1. If tensioner (1) assembly is being replaced, install tensioner and mounting bolts. Tighten bolts to 28 Nm (250 in. lbs).
2. Retract tensioner (2) if required.




CAUTION: The timing chain must be installed with the single plated link aligned with the dot and or paint marking on the camshaft sprocket. The crankshaft sprocket is aligned with the dot and or paint marking on the sprocket between two plated timing chain links.

CAUTION: The camshaft pin and the slot in the cam sprocket must be clocked at 12:00. The crankshaft keyway must be clocked at 2:00. The crankshaft sprocket must be installed so that the dots and or paint marking is at 6:00.

3. Place both camshaft sprocket and crankshaft sprocket on the bench with timing marks on exact imaginary center line through both camshaft and crankshaft bores.
4. Place timing chain around both sprockets.
5. Lift sprockets and chain (keep sprockets tight against the chain in position as shown).
6. Slide both sprockets (2,3) evenly over their respective shafts and check alignment of timing marks.
7. Install the camshaft bolt. Tighten the bolt to 122 Nm (90 ft. lbs.).




8. Remove tensioner pin. (1) Again, verify alignment of timing marks.
