(B) Camshaft lobe lift
Use the following procedure in order to determine the camshaft lobe lift:
- Measure the camshaft lobe height (C).
- Measure the base circle (D).
- 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
- Inlet lobe ...
9.431 mm (0.37130 inch) - Exhaust lobe ...
8.515 mm (0.3352 inch) - Injector lobe ...
10.908 mm (0.42945 inch) - Exhaust lobe ...
The maximum permissible difference between the actual camshaft lobe lift in Step 3 and the specified camshaft lobe lift is
