9.4.13.4 Dual Power Cylinder Reassembly (See Figure #64)
If the rod was removed from the center plate, reassemble as follows:
Remove both O-rings from their grooves in the center plate. Lubricate new O-rings and carefully
install them in their grooves.
Clean rod surface thoroughly. Grease the rod with Bettcher
®
Max-Z-Lube and slowly slide the
threaded end through the O-rings in the bore of the center plate. Use a gentle twisting motion to
avoid damaging or unseating the O-rings. Place a 1/8 inch (3mm) diameter rod through the rod
end bearing to act as a handle, install the rear piston over the end of the rod, then install the piston
screw and tighten it securely. Remove the 1/8 inch (3mm) diameter pin.
Lubricate both piston O-rings thoroughly with Bettcher
®
Max-Z-Lube. Carefully fit the front
cylinder over the rod, using a gentle twisting motion as the rod passes through the lip seal, bearing,
and wiper on the nose of the cylinder. Rotate the cylinder until its air fitting is offset to the same
side as the fittings on the center plate. Install the rear cylinder over the rear piston in the same
manner, using a gentle twisting motion and rotating it so its air fitting is also offset to the same
side as the fittings on the center plate. Align the four holes, install the screw, flat washers, lock
washers, and hex nuts per Figure #63. Be sure the O-rings are lubricated and seated in the grooves
in the cylinder faces, and then tighten all four screws securely.
Perform leak test. (See Section 9.1.3)
