Note: Lubricate the camshaft lobes with a 50/50 mixture of 8T-2998 Lubricant and clean engine oil.
(4) Bearing journal
- Diameter of the bearing journals ... 84.85 ± 0.02 mm (3.341 ± 0.001 inch)
Note: Lubricate the camshaft bearings with clean engine oil prior to installing the camshaft.

(A) Camshaft lobe lift
-
Specified camshaft lobe lift
- Exhaust lobe ... 8.515 mm (0.3352 inch)
- Inlet lobe ... 9.702 mm (0.3820 inch)
- Injector lobe ... 10.451 mm (0.4115 inch)
- Inlet lobe ... 9.702 mm (0.3820 inch)
To find the lobe lift, use the procedure that follows:
- Measure camshaft lobe height (B) .
- Measure base circle (C) .
- Subtract the base circle measurement (Step 2) from the camshaft lobe height (Step 1). The difference is the actual lobe lift.
Maximum permissible difference between the actual lobe lift and the specified lobe lift of a new camshaft ... 0.13 mm (0.005 inch)
