| NOTICE |
|---|
Correct cam segment relationship (timing) must be observed at assembly. If the cam segments are out of time, serious engine damage will occur. |
Note: The position of the single dowel in relation to the variable dowel determines the letter designation of the cam journals. The single dowel is located on the same end as the locating groove. The variable dowel is located on the end opposite the locating groove.
(3) Location of the single dowel in the face of the camshaft journal
Distance from the top of the dowel to the camshaft bearing journal ... 15.0 ± 0.5 mm (0.59 ± 0.02 inch)

(11) Specified camshaft lobe lift
To find the specified camshaft lobe lift, use the procedure that follows:
- Measure the total height of the camshaft (12) .
- Measure base circle (13) .
- Subtract base circle (13) from the total height of camshaft (12). The difference is the specified camshaft lobe lift (11) .
- Specified camshaft lobe lift (11) for the camshaft is the following value:
Exhaust lobe ... 19.500 mm (0.7677 inch)
Inlet lobe ... 19.500 mm (0.7677 inch)
Fuel injection pump camshaft lobe ... 21.473 mm (0.8454 inch)
