Socket Head Cap Screws supplied. Install these bolts slightly loose.

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.

Torque Loose Bolts. Remove each of the three (3) Cam Sprocket mounting bolts, one
at a time, and apply the

Thread Locking Compound, then torque each bolt to 300 in-lb

(25 ft-lb).

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. Assembly lube will stay on the
sprockets until the engine is started.

Assemble the engine. Install the timing cover, timing cover gasket and accessories.
