NOTE: At this point, oil the camshaft bearings,
cam lobes, and the three seating journals on the
cylinder head.
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. When the camshaft assembly is seated, ensure the
following.
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.
CAUTION
If any of the above factors are not as stated, go back to
step 13 and carefully proceed.
16. Place the tab washer onto the sprocket making
sure it covers the pin in the alignment hole.
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.
17. Apply red Loctite #271 to the first cap screw
securing the sprocket and tab washer to the cam-
shaft; then install the cap screw and tab washer.
Tighten cap screw only until snug.
