Install the camshaft sprocket onto the camshaft so the camshaft sprocket boss fits into the
appropriate hole on the camshaft sprocket. Make sure the camshaft sprocket boss is facing
up so it is visible above the edge of the cylinder head as shown. Align the horizontal marks
on the camshaft sprocket with the top edge of the cylinder head as shown. Fit the camchain
over the camshaft sprocket.
For correct engine timing the marks on the camshaft sprocket must be even with the
cylinder head mating surface at the same time the "T" mark is lined up with the with the
index notch in the timing inspection hole. The camshaft lobes should be facing down and
their should be slack in the rocker arms.
Apply a small amount of blue Loctite (non-permanent) to the threads of the camshaft
sprocket bolts. Thread in the camshaft sprocket bolts and tighten to specification using a 5
mm Allen socket.
