(A) Actual camshaft lobe lift

(B) Height of the camshaft lobe

(C) Base circle

To determine the lobe lift, use the procedure that follows:

1. Measure the height of the camshaft lobe (B).

2. Measure the base circle (C).

3. 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.
