14. With the cam lobes directed down (toward the
piston), maneuver the camshaft/sprocket assem-
bly 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 must be parallel
with the valve cover mating surface. If rotating the
camshaft is necessary for alignment, do not allow
the chain and sprocket to rotate and be sure the
cam lobes end up in the down position.

15. 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 camshaft/sprocket assembly onto the cylin-
der 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 align-
ment hole (smallest) are aligned.
16. Place the tab-washer onto the sprocket making
sure it covers the pin in the alignment hole.
