Camshaft Timing Tips

7/7/2016
Adjusting Cam Timing

The crankshaft sprocket features three keyways to allow you to advance or retard your camshaft with using offset keys or bushings. Follow the instructions for your engine. CAUTION: You must recheck your piston to valve clearance after advancing or retarding you camshaft timing.

EXAMPLE: To advance the camshaft, you install the crankshaft sprocket using the keyway marked A. Then you align the A mark on the outer edge of the sprocket with the dot marked on the camshaft sprocket, mark to mark. You must use the corresponding marks on the crankshaft sprocket for proper installation.
