HANDLE

To inspect air cylinder bore, remove base cover (704125). Any further disassembly will require removal of the head cylinder ass'y

(730398) first. For complete disassembly, start by removing base cover (704125). Next, holding tool upright, remove four button-head

cap screws (A-928). Lift head cylinder (730398) from handle (704132) and set aside o'ring (S832) and gasket (745124). Empty all

hydraulic fluid into a container. Place piston rod wrench (730151) down into top of power cylinder (730237), into slot of piston rod

assy. (730233). 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 (703233), tap or push on the piston rod wrench to eject air piston ass'y (704121)

from bottom of handle. After removal of air piston ass'y (704121), slide piston rod ass'y (730233) back up to the end of its travel.

Using packing plug wrench (704150) remove packing plug (704118). With packing plug removed (704118), power cylinder (730237)

can be removed by pushing on power cylinder tool (704151) when inserted into top of power cylinder (730237).

To reassemble the handle (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 (730233) and tap the

piston rod ass'y (730233) 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 (730233). With the piston rod ass'y 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 S832 o'ring. Replace gasket (745124) and o'ring (S832), just prior to replacing

head cylinder (730398). (See Filling & Bleeding instructions).
