17. Keeping tension on the opposite cam chain, rotate
the crankshaft until the second cap screw securing
the sprocket to the camshaft can be installed; then
install the cap screw (threads coated with red Loctite
#271) and tighten to 11 ft-lb. Bend the tab to secure
the cap screw.

18. Rotate the crankshaft until the first cap screw (from
step 16) can be tightened; then tighten to 11 ft-lb.
Bend the tab to secure the cap screw.

20. 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 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 properly
aligned to the head.

E. Camshaft alignment pin and sprocket alignment
hole (smallest) are aligned.
CAUTION
Failure to keep tension on any loose cam chain may
cause severe engine damage.

AT THIS POINT
Return the engine to TDC on the front cylinder making
sure the cam lobes are directed downward to ensure
correct starting point for step 19.
CAUTION
If any of the above factors are not as stated go back to
step 19 and carefully proceed.
