Installation Instructions

9-3113A 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)

Depth Micrometer or Good Steel Scale

SUPPLIES:

Assembly Lube or Camshaft Lube

Thread Locking Compound (Loctite® #271 or equiv.)

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

2. 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.

3. Install the Dowel Pin. Remove the old dowel pin by clamping the pin in a vise and

carefully prying the camshaft away. Trial fit the new dowel pin in the camshaft, making

sure that it is fully seated in the camshaft. The pin should protrude 9/16" to 19/32" from

cam nose. If the pin is too long, grind it until the length is correct. Remove the pin and

apply the thread locking compound to the end of the pin. Press the dowel pin back into

place, making sure that it is fully seated in the camshaft.

4. Align the Engine. Rotate the crankshaft until the number one piston is at top dead

center. The crankshaft key should be pointing up to the right. Rotate the camshaft until

the dowel pin is pointing straight up.

5. 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
