5. Adjust the valves if necessary by loosening
the lock nut and turning the adjustment screw

8. Rotate the engine in the normal direction of
rotation (counterclockwise from the flywheel

center of the compression stroke.
a. Check the rocker arms and push rods on
the number 3 cylinder.
b. If the rocker arms and push rods are loose,
the number 3 cylinder is at top dead center
of the compression stroke.
c. If the rocker arms and push rods are tight,
the number 3 cylinder is at top dead center
of the exhaust stroke. Rotate the engine
360 degrees to place the number 3 cylinder
at top dead center of the compression
stroke.
9. Check and adjust both valves for the number 3
cylinder.
10. Rotate the engine in the normal direction of
rotation (counterclockwise from the flywheel
end) until the number 2 cylinder is at top dead
center of the compression stroke.
a. Check the rocker arms and push rods on
the number 2 cylinder.
b. If the rocker arms and push rods are loose,
the number 2 cylinder is at top dead center
of the compression stroke.
c. If the rocker arms and push rods are tight,
the number 2 cylinder is at top dead center
of the exhaust stroke. Rotate the engine
360 degrees to place the number 2 cylinder
at top dead center of the compression
stroke.
