HANDLE SUB-ASSEMBLY
Disconnect tool from air supply and remove parts (23) through (27).
Place piston rod wrench (700A61) down into the top of the handle (30), into the hex socket in the head of the power piston
rod (35). While holding this wrench, remove the locknut (22) using the 7/16" socket.
Still holding the piston rod wrench, remove the air piston (21) using the packing plug wrench (700B65) by turning
counterclockwise. When air piston is completely freed from the piston rod, tap or push on the piston rod wrench to eject the
piston from bottom of handle.
Slide power piston rod (35) back up to the end of its travel. Using the packing plug wrench (700B65), remove packing
plug (18). It may be necessary to hold the handle upside down in a vise while removing the packing plug. The O-rings
(16) and backup rings (15) are best removed and replaced by using a thin bent hook.
Power cylinder (31) can be tapped out by lowering power cylinder tool (700A62) down into the top of the handle on to top of
cylinder.
To reassemble the handle, reverse the above procedure, being certain that all the O-rings are properly lubricated before
installation. Attach the seal guide (700A60) to the piston rod (35) and with a mallet, tap the piston rod through the packing
plug (18). When reassembling a replacement air piston, items (19) through (22), follow the instructions given below:
Clamp piston rod wrench (700A61) in a vise with the hex shaft pointed up.
Turn the handle upside down and place the hex end of the power piston rod (35) onto the wrench. Push handle casting down
until it stops.
Assemble seal (20) and back-up rings (19) to air piston (21).
Place the air piston (21) into handle bore. Thread the locknut (22) onto the power piston rod (35) and tighten between
50 in.-lb (5.65 N-m) and 59 in.-lb (6.67 N-m).
