Cylinder Rebuilding
An official procedure for cylinder rebuilding is documented in the ShowBiz Pizza Place Operations Manual from 1981.
 * 1) Remove front or rear face of cylinder
 * 2) Remove piston
 * 3) Remove nose seal and "O" rings
 * 4) Clean all parts with a clean rag and denatured alcohol
 * 5) Coat piston and new seals with packer lube
 * 6) Install the new "O" rings (flanges facing each other)
 * 7) Coat the cylinder wall with parker "O-ring" lube
 * 8) Lube piston rod with 10 weight non-detergent oil
