COMP Cams

3-keyway adjustable crank sprocket timing

sets allow crankshaft timing adjustment by ± 4 degrees.
Remembering the camshaft angle is half of the crankshaft
angle, therefore the camshaft will advance or retard by ± 2
degrees. Note: Notice the shape of the internal crankshaft
keyways. They are shaped to coincide with the timing
marks to be used. They have a round, rectangular and
square at the top of the crankshaft keyway to help you
position the crank gear as desired.

To keep factory timing use the “O” crankshaft keyway and
timing mark.

To advance timing use the “Δ” crankshaft keyway and
timing mark.

To retard timing use the “□” crankshaft keyway and timing mark.
