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.

CAUTION
If any of the above factors are not as stated, go back to
step 12 and carefully proceed.

alignment pin falls out, severe engine damage will
result.
