9.4.13.2 Single Power Cylinder Reassembly (See Fig. #62)
If the rod was removed from the piston, reassemble them as follows:
Clean rod surface thoroughly. Grease the rod with Bettcher
®
Max-Z-Lube and slowly slide the
threaded end into the base from the outside (wiper end). Put a clevis pin or other rod of 1/8 inch
(3mm) diameter into the rod end bearing to act as a handle. Clean mating surface of piston, place
it onto the threaded end of the rod and install piston screw tightly. Remove the 1/8 inch (3mm)
diameter pin.
Otherwise: Check that there are no scratches or burrs on the rod, especially at the cross hole.
Grease the rod with Bettcher
®
Max-Z-Lube and slowly slide it into the base from the inside. Slide
the piston up against the base.
Wipe the cylinder bore clean and apply a thin film of Bettcher
®
Max-Z-Lube. Apply Bettcher
®
Max-Z-Lube to both O-rings.
Position the wear strip into
Rear
groove of piston and hold it in place with fingers while sliding
cylinder over it with the other hand.
On the small cylinder it may be easier to install the piston and rod with the wear strip into the
cylinder before putting the base onto the rod.
Before pushing the base fully into the cylinder, rotate base until the base air fitting is on the
opposite side of the clevis as the rear fitting. (See Figure #62). Rotate the base until the screw
holes are in-line with the side holes of the cylinder.
Push the base into the cylinder until the front face is flush. Rotate the base slightly if needed to
center the screw holes.
Install the flat head screws. Tighten each half-tight, then full tight to let the components align
themselves.
Perform leak test (see Section 9.1.3).
