REMOVAL AND INSTALLATION

Camshaft

 

Removal

  1. Remove the engine (6007).

  1. NOTE: The camshaft (6250) can be removed without removing the cylinder heads (6049) and valve tappets (6500) if desired. Remove the rocker arms and push rods (6565) making sure to keep them in order for assembly. Rotate the engine on the engine stand until in the vertical position, tipped slightly back so the valve tappets will slide away from the camshaft. Rotate the camshaft three or four times to push the valve tappets away from the camshaft lobes.

    Before removing the camshaft, inspect camshaft sprocket backlash. Refer to Drive Gear Backlash (All Gears) in the Service Procedures portion of this section. Inspect camshaft sprocket end play. Refer to Section 03-00.

  1. Remove the engine front cover (6019).

  1. Remove the valve tappets.
