See Figure C 1-5.
1. Remove the hex nuts (20) and long hex-head screws (1) from the
cylinder heads (2 and 16).
CAUTION: See Figure C 1-3. If you did not remove the actuator cartridges
from the cylinder heads, be careful when handling the cylinder heads so you
do not damage or break off the actuator plunger (6A) pins.
2. Lift the upper cylinder head (2) off the air cylinder (15).
3. Slide the air cylinder off the air piston (22).
CAUTION: Do not scratch or score the connecting rod. Sharp edges will
damage the U-cup seal and cause it to leak.

pulling the connecting rod (21) through the U-cup seal (17) and out of
the lower cylinder head.
5. Remove the four socket-head screws (19) and lock washers (27) from
the bottom of the lower cylinder head with a

remove them. If you replace them, apply Loctite 242 Removable thread
adhesive to the threads that screw into the lower cylinder head before
installing the studs.
