(6) Camshaft lobe lift
Specified camshaft lobe lift (6)
- Exhaust lobe ... 9.550 mm (.3760 inch)
- Inlet lobe ... 11.371 mm (.4477 inch)
- Injector lobe ... 10.474 mm (.4124 inch)
- Inlet lobe ... 11.371 mm (.4477 inch)
(7) Camshaft lobe height
(8) Base circle
Specified base circle (8)
- Exhaust lobe ... 55.0 ± 0.4 mm (2.17 ± .02 inch)
- Inlet lobe ... 51.0 ± 0.4 mm (2.01 ± .02 inch)
- Injector lobe ... 52.2 ± .4 mm (2.0551 ± .02 inch)
- Inlet lobe ... 51.0 ± 0.4 mm (2.01 ± .02 inch)
To find the lobe lift, use the procedure that follows:
- Measure the camshaft lobe height (7) .
- Measure the base circle (8) .
- Subtract 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 (6) .
Maximum permissible difference between actual lobe lift and the specified lobe lift of a new camshaft ... ± 0.13 mm (.005 inch)
