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

Lubricate the camshaft journals and the bearings with clean engine oil.
Install 3 M8 - 1.25 x 100 mm (M8 - 1.25 x 4.0 in) bolts into the camshaft front bolt holes.

NOTE: 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 bolts as a handle, carefully install the camshaft into the engine block.
Remove the 3 bolts from the front of the camshaft.
