Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice.
Please read this instruction sheet carefully before beginning installation, and also take a moment to
review the included limited warranty information.
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.
INSTALLATION INSTRUCTIONS:
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 depend 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 place on the camshaft and crankshaft. Slide the crankshaft
sprocket onto the crankshaft while sliding the camshaft sprocket onto the camshaft. Make sure that the
sprockets are fully seated on their shafts.
6. Install the Fuel Pump Eccentric. Install the eccentric onto the camshaft sprocket making sure that
the dowel pins fully engage the proper holes in the eccentric. Be sure that the dowel pin installed
