HANDLE

To inspect air cylinder bore, remove base cover (704125). Any further disassembly will require removal of the manifold-handle

(744303) first. For complete disassembly, start by removing base cover (704125). Next, holding tool upright, remove four socket-

head cap screws (A-928). Lift manifold-handle (744303) from handle (704132) and set aside o'ring (S832) and gasket (704129). Emp-

ty all hydraulic fluid into an approved container and dispose of in accordance with all environmental laws and regulations applicable

in your area. Place piston rod wrench (704149) down into top of power cylinder (751131), into the hex of piston rod ass'y (704138).

While holding this wrench, remove flexlock nut (400559) using a 7/16" socket wrench. Still holding piston rod wrench, remove air

piston ass'y (704121) using packing plug wrench (704150), by turning counterclockwise. When air piston ass'y (704121) is com-

pletely free from piston rod ass'y (704138), tap or push on the piston rod wrench to eject air piston ass'y (704121) from

bottom of handle (704132). After removal of air piston ass'y (704121), slide piston rod ass'y (704138) back up to the end of its

travel. Using packing plug wrench (704150) remove packing plug (704118). With packing plug ( 704118) removed, power cylinder

(751131) can be removed by pushing on power cylinder tool (704151) when inserted into top of power cylinder (751131).

To reassemble the handle, reverse the above procedure, being certain that all o'rings are properly lubricated before installation.

Torque packing plug (704118) to 45 foot lbs. Attach the seal guide (704152) to the piston rod ass'y (704138) and tap the piston rod

ass'y (704138) through the packing plug (704118). Attach air piston ass'y (704121) and flexlock nut (400559) torque flexlock nut to

40 inch lbs. With the piston rod ass'y (704138) in the down position, fill oil passage on top of handle with automatic transmission

fluid, Dexron III or equivalent, when looking at top of handle the oil passage is the hole that has a counterbore for o'ring (S832). Re-

place gasket (704129) and o'ring (S832), just prior to replacing manifold-handle (744303). (See Filling & Bleeding instructions.)

AIR VALVE

To disassemble, first disconnect tool from its air source. Remove pin (704244) and muffler (704146). Insert valve extractor (S1178)

into end of valve plug (704145) and pull it out. Using the same procedure, pull out valve spool ass'y (703142). NOTE: It should nev-

er be necessary to remove valve sleeve (703139) unless the ports in the valve sleeve are plugged from contaminated air. If ports are

plugged, use needle nose pliers to grasp end of spring (704141), turning clockwise and pulling to dislodge from groove in casting.

NOTE: 704162 valve spring installation tool will facilitate the proper installation of the spring (704141), valve sleeve (703139) can be

pulled out using valve sleeve removal tool 704163.
