   Note: Lubricate Tooling (B) for easier removal of the camshaft. Lubrication also prevents damaging the camshaft lobes and the camshaft bearings.

6. Use two people to remove camshaft (6). The weight of camshaft (6) and the camshaft gear is approximately 34 kg (75 lb). Carefully remove camshaft (6) from the engine. Support the weight of the camshaft during removal.

   Note: Rotate the camshaft during removal. This action will prevent the camshaft from binding in the camshaft bearings.

Installation Procedure

1. Install camshaft (6) in the reverse order of removal.

   Note: Ensure that camshaft (6) and Tooling (B) are clean. Apply clean engine oil to the lobes and journals of camshaft (6) and Tooling (B).

   Note: During installation of camshaft (6), rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores.
