75. CYLINDER CLEARANCE
The clearance between the cylinder rim and front
panel must be adjusted so the cylinder is centered
within the front panel opening when the cylinder
is fully loaded and is turning. However, the
adjustment should be made when the cylinder is
empty.
NOTE: If the cylinder is not properly adjusted, the
cylinder rim will rub against the front panel.
a. Open loading door.
b. Check the gap between the center of the front
panel top flange and the cylinder rim. Proper
adjustment is when the gap is 8/32 inch ± 3/32
inch. Refer to Figure 31. Perform steps “a”
through “g” to adjust the cylinder rim/front
panel flange clearance.
c. Check the cylinder fore/aft clearance between
the inside front of the cylinder and the edge of
the front panel flange. Proper adjustment is
when the gap is 9/32 inch ± 1/32 inch. Refer to
Figure 31. Perform steps “h” through “m” to
adjust the cylinder fore/aft clearance.

or the other adjusting screw in or out to adjust side
clearance.

the adjusting screw locknuts and the rear
bearing mounting screws.
