7. Lubricate camshaft journals and camshaft
bearing surfaces (in cylinder block) with
clean engine oil.

function properly.

the camshaft installation tool in place. Align
timing marks on the camshaft with timing
mark on the main crankshaft drive gear.

The use of the installation tool will make it easy to
slide the camshaft into the block while protecting
the cam and bushings from damage.
Refer to Figure 6-48.

the block using the two patch-lock 12-point
capscrews (3) and hardened washers.
