10. Using a crisscross pattern, tighten the four cap
screws (from step 8) initially to 20 ft-lb; then in 10
ft-lb increments, tighten to a final torque of 40 ft-lb.
11. Tighten the 8 mm nuts from step 9 to 18 ft-lb and the
6 mm nuts to 10 ft-lb; then tighten the two cylinder-
to-crankcase nuts (from step 4) securely.

15. 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 and sprocket is necessary for alignment, do not
allow the crankshaft to rotate and be sure the cam
lobes end up in the down position.
