| Use the following procedure to determine the camshaft lobe lift:
1. Measure the camshaft lobe height (C). 2. Measure the base circle (D). 3. Subtract the base circle measurement in Step 2 from the camshaft lobe height in Step 1. The difference is the actual camshaft lobe lift (B). Specified camshaft lobe lift: For inlet lobe is For exhaust lobe is For injector lobe (right bank) is For injector lobe (left bank) is The maximum permissible difference between the actual camshaft lobe lift in Step 3 and the specified camshaft lobe lift is |
