NOTE:
If camshaft replacement is required, the valve lifters must also be replaced.

Lubricate the camshaft journals and the bearings with clean engine oil.
Install the camshaft sprocket bolt into the camshaft front bolt hole.

CAUTION:

All camshaft journals are the same diameter, so care must be used in removing or installing the camshaft to avoid damage to the camshaft bearings.

Using the bolt as a handle, carefully install the camshaft into the engine block.
Remove the bolt from the front of the camshaft.
