NOTE: At this point, oil the camshaft bearings, cam
lobes, and the three seating journals on the cylinder.
13. 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 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.

14. 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 cylinder
ensuring the following.
GZ190B
A. Piston still at top-dead-center.
B. Camshaft lobes directed down (toward the pis-
ton).
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.
15. Place the tab-washer onto the sprocket making
sure it covers the pin in the alignment hole.

16. Install the first cap screw (threads coated with red
Loctite #271) securing the sprocket and
tab-washer to the camshaft. Tighten only until
snug.

CAUTION
If any of the above factors are not as stated, go back to
step 11 and carefully proceed.
CAUTION
Care must be taken that the tab-washer is installed
correctly to cover the alignment hole on the sprocket.
If the alignment pin falls out, severe engine damage
will result.
