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 screws (A-928). Lift manifold-handle (744303)

from handle assy (704132) and set aside o'ring (S832) and gasket (704129). Empty all hydraulic oil into an approved container and dispose of in

accordance with all environmental 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

completely 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 assy

(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 cylin-

der tool (704151) when inserted into top of power cylinder (751131).

To reassemble the handle assy (704132), 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. Attach air piston

ass'y (704121) to piston rod ass'y (704138). With the piston rod ass'y (704138) in the down position, fill oil passage on top of handle assy (704132)

with automatic transmission oil, Dexron III or equivalent, when looking at top of handle assy (704132) the oil passage is the hole that has a counter-

bore for (S832) o'ring. Replace gasket (704129) and o'ring (S832), just prior to replacing manifold-handle (744303). (See Filling & Bleed-

ing instructions.)

AIR VALVE

WARNING

Disconnect tool from its air source before disassembly.

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 never

be necessary to remove valve sleeve (703139) unless the ports in the 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:

valve spring tool (704162) will facilitate the proper installation of the spring (704141), valve sleeve (703139) can be pulled out using

valve sleeve removal tool (704163).
