1. Rotate the camshaft until the dowel pin on its front end is 

located as shown in the illustration.
NOTE: Placing the camshaft in the illustrated position mini-
mizes the amount of cam lift, making it easier to install the 
rocker arm and shaft assembly.

2. Temporarily tighten the rocker shaft with the bolts so that all 

rocker arms on the inlet valve side do not push the valves.
