Installation Instructions

9-3122A Hex-A-Just

Roller Timing Set

with Adjustable Fuel Pump Eccentric

BEFORE YOU BEGIN: READ ALL OF THESE INSTRUCTIONS FIRST !!!

Note: The installation procedures which follow assume that the engine has been disassembled

and cleaned as it would be for a normal timing set change.

YOU WILL NEED:

TOOLS:

Torque Wrench
Degree Wheel (Optional, but Recommended)

SUPPLIES:

Assembly Lube or Camshaft Lube
Thread Locking Compound (LockTite® #271 or equiv.)

Prepare the Engine. Loosen all rocker arms so that the camshaft can rotate freely.

Clean everything! Make sure that the engine mounting surfaces and timing set
components are as clean as possible. The life of the chain and sprockets depends on it.

Install the Dowel Pin. If your engine originally used the two-piece fuel pump eccentric
and the short dowel pin, remove the old dowel pin. Press the new dowel pin into place,
making sure that it is fully seated in the camshaft.

Note! Some older engines have a spacer on the camshaft and a camshaft sprocket which
is flat on the back. If your engine has one of these spacers, remove and discard it. The
new camshaft sprocket has the spacer machined in.

Align the Engine. Rotate the crankshaft until the number one piston is at top dead
center. The crankshaft key should be pointing straight up. Rotate the camshaft until the
dowel pin is pointing straight down.

Assemble the Timing Set. Select the appropriate keyway and timing mark on the
crankshaft sprocket for the camshaft timing baseline desired. We recommend the
Standard Timing position, which uses the round timing mark and round keyway. Loop the
chain over the camshaft sprocket. Align the camshaft and crankshaft timing marks and
loop the chain around the crankshaft sprocket. Lift the sprocket and chain assembly into
