Illustration 2 g00295323 (A) Actual camshaft lobe lift (B) Height of the camshaft lobe (C) Base circle To determine the lobe lift, use the procedure that follows:
Measure the height of the camshaft lobe (B).
Measure the base circle (C).
Subtract the base circle that is found in Step 2 from the height of the camshaft lobe that is found in Step 1. The difference is the actual camshaft lobe lift.
