5. Install the Camshaft Thrust Bearing. Install the Thrust Needle Bearing on the back

side of the camshaft gear with the black side of the bearing facing gear hub, so the

silver side of the bearing will be facing the block.

6. Mount the Camshaft Sprocket. Loop the chain over the camshaft sprocket. Align the

camshaft and crankshaft timing marks and loop the chain around the crankshaft sprocket.

Lift the camshaft sprocket into place on the camshaft, with the Thrust Bearing and Hex-

A-Just

Bushing in place. Be sure that the timing mark aligns with the crankshaft timing

mark, and that the Thrust Bearing has not slipped off of the shoulder on the sprocket hub.

Bolt it in place using the existing GM bolts or equivalent. Install these bolts slightly loose.

7. Install the Cam Button. Install the cam button (Part Number 9-200) using the

instructions enclosed with it.

8. Adjust the Camshaft Timing. Do NOT try to turn

the camshaft with the bushing unless there is NO

LOAD on the camshaft. There must be NO VALVE

SPRING PRESSURE against the camshaft or the

Hex-A-Just

bushing will SPLIT. Make sure that

the three camshaft bolts are LOOSE. For a simple

installation, adjust the Hex-A-Just

bushing to the

desired timing setting (Figure 2). For a more

accurate installation, use a degree wheel. The

degree wheel method is strongly recommended.

9. Torque Loose Bolts. Remove each of the three bolts, one at a time, and apply the

thread Locking Compound, then torque each bolt to 300 in-lb (25 ft-lb).

10. Lubricate the Timing Set. Make sure that the engine oil has a clear path to the timing

set through the lifter valley oil drain-back holes, or through some other means. A timing

set requires plenty of oil to survive. Before installing the timing cover gasket and timing

cover, pour plenty of assembly lube over the sprockets and bearings. Assembly lube will

stay on the sprockets until the engine is started.

11. Install the Timing Cover and Gasket. Install the timing cover gasket (Part Number 9-

207) using a small amount of gasket sealer if desired. Mount the Cloyes Quick Button

Polished Aluminum Two-Piece Timing Cover (Part Number 9-227) and install the ten(10)

mounting bolts. Torque these bolts to 160 in-lb (13 ft-lb).
