This Illustration shows the location of the dowels on the camshaft bearing journal. (X) Location of the single dowel in the face of the camshaft bearing journal. (Y) Location of the variable dowel in the face of the camshaft bearing journal. (Z) Locating groove.
Illustration 2 g00615517
Illustration 3 g00615537Note: 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 that is opposite of the locating groove.Each journal has several dowel holes on the side opposite the locating groove. There is only one dowel hole on the side of the locating groove. The letter designation of each journal gives the dowel location of that journal for the side opposite the locating groove.

This Illustration shows the letter designation of G3612 camshaft journals.
Illustration 5 g00615568
This Illustration shows the letter designation of G3616 camshaft journals.
Before assembly, check the location of the dowel and the height of each camshaft journal. The assembled height of each dowel must be 15.0 0.5 mm (0.59 0.02 inch). Note: Install the camshaft journals with the locating groove toward the front of the engine for both standard rotation engines and reverse rotation engines.Install the camshaft segments with the groove toward the front of the engine for standard rotation engines.Install the camshaft segments with the groove toward the rear of the engine for reverse rotation engines.
