(1) The end of the camshaft that is marked "F" must be placed at the front of the engine. Lubricate the camshaft bearings, the journals, and the lobes with a 50/50 mixture of 8T-2998 Lubricant and clean engine oil.

(A) Diameter of camshaft journal ... 84.85 ± 0.02 mm (3.341 ± 0.001 inch)

(B) Camshaft lobe lift

Use the following procedure in order 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

Inlet lobe ... 9.619 mm (0.3787 inch)

Exhaust lobe ... 8.515 mm (0.3352 inch)

Injector lobe (right bank) ... 10.337 mm (0.4070 inch)

Injector lobe (left bank) ... 10.338 mm (0.4070 inch)

The maximum permissible difference between the actual camshaft lobe lift in Step 3 and the specified camshaft lobe lift is 0.13 mm (0.005 inch).
