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.

NOTE: Refer to Fastener Notice in Cautions and Notices.

IMPORTANT:

Install the retainer plate with the sealing gasket facing the engine block.
The gasket surface on the engine block should be clean and free of dirt or debris.
