Timing Belt: Adjustments

Adjusting Timing






1. Remove the timing belt outer cover.

2. If the belt timing is incorrect, loosen the belt tensioner adjustment screw, position the Camshaft Belt Tensioner Tool T74P-6254-A or equivalent, as shown on the tension spring rollpin and release the belt tensioner. Tighten the adjustment screw to hold the tensioner in released position.






3. Remove crankshaft pulley and belt guide.
4. Remove the drive belt and inspect it for wear or damage. If the belt is damaged, replace it.
5. Position the crankshaft sprocket and the camshaft sprocket. Remove the distributor cap and set the distributor rotor to No. 1 firing position by turning the auxiliary shaft.
6. Install the timing belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets. Align the belt fore-and-aft on the sprockets.
7. Loosen the tensioner adjustment bolt to allow the tensioner to move against the belt. To ensure the belt does not jump time during rotation in Step 8, remove the spark plugs.
8. Rotate the crankshaft two complete turns in normal rotation to remove the slack from the belt. Tighten tensioner adjustment and pivot bolts to specification. Check the alignment of the timing marks.
9. Install the crankshaft pulley and belt guide.
