How to use this Quick Identification Guide |
- Measure camshaft length. Measure from under the cam head to the beginning of the lock ring groove.
- Locate camshaft length in the Camshaft Quick Identification Guide. Camshafts are listed in order of length, from shortest to
longest.
- After finding camshafts in the Cam Length column, determine camshaft head style, using the Head Styles chart and head width
dimensions.
- Narrow your final selection by Diameter at Spline End and Number of Splines, Diameter at Spider and any other information listed.
|
These graphics are for identification purposes only. Dimensions in actual camshafts may vary slightly. |
