Measure the camshaft lobe height (8).
Measure the base circle (9).
Subtract the diameter of the base circle that is found in Step 2 from the lobe height that is found in Step 1. The difference is the actual camshaft lobe lift (7). Note: Use the appropriate Guidelines for Reusable Parts publication in order to determine if the wear of the camshaft is excessive.
