20. With the alignment pin installed in the rear camshaft,
loosely place the cam sprocket (with the recessed
side facing the cam shaft lobes) onto the camshaft.
At this point, do not “seat” the sprocket onto the
shaft.

NOTE: At this point, oil the camshaft bearings, cam
lobes, and the three seating journals on the cylinder.
21. With the cam lobes directed down (toward the pis-
ton), maneuver the camshaft/sprocket assembly
through the chain and towards its seating position;
then loop the chain over the sprocket.
NOTE: Note the position of the alignment marks on
the end of the camshaft. They should be parallel with
the plane of the cylinder head. If rotating the cam-
shaft is necessary for alignment, rotate the sprocket
inside the chain until the alignment pin can be
engaged in the sprocket with the camshaft in the
nearest possible position to parallel.

22. Seat the cam sprocket onto the camshaft making sure
the alignment pin in the camshaft aligns with the
smallest hole in the sprocket; then place the cam-
shaft/sprocket assembly onto the cylinder ensuring
the following.

A. Piston still at top-dead-center.
B. Camshaft lobes directed down (toward the piston).
C. Camshaft alignment marks parallel to the valve
cover mating surface.
D. Recessed side of the sprocket directed toward the
cam lobes.
E. Camshaft alignment pin and sprocket alignment
hole (smallest) are aligned.
CAUTION
If any of the above factors are not as stated go back to
step 19 and carefully proceed.
