244BT Pneudraulic Installation Tool (HK1113)
12
EQUIPMENT REQUIRED:
- Shop airline with 90-100 psi max.
Air regulator
Fill Bottle 120337 (supplied with
tool).
Fill Tool Assy 112465
Large flat blade screwdriver
Stall Nut 124090
Nose assembly
Fasteners (Optional)
PREPARATION:
1. Remove preset regulator and install an adjustable air
regulator in airline and set pressure to 20-40 psi.
2. Fill bottle almost full of DEXRON III - ATF (automatic
transmission fluid).
NOTE: Refill tool only when red
line on plunger drops below the red line on the
reservoir housing or when tool is rebuilt.
STEP 1:
Screw Fill Tool into Reservoir Plunger, pull
Plunger into Reservoir Housing and lock Fill Tool in full
forward position by tilting handle (long side touching
tool) and locking in place. (Figures 10 & 14)
STEP 2:
Remove Relief and Check Valve Plugs, Guides,
Springs and Balls from ports in head. Reinstall Plug and
Sleeve in head in Relief Valve port (front of tool).
STEP 3:
Screw retaining nut onto Head Assembly. Screw
Stall Nut onto Hydraulic Piston and tighten to ensure
full thread engagement. Back off Retaining Nut until it
engages Stall Nut. Check Hydraulic Piston location.
Piston
must be all the way forward and locked with Stall Nut
and Retaining Nut.
STEP 4:
Attach the tool air source momentarily to seat
Air Piston at bottom of Air Cylinder, then disconnect tool.
With reservoir fill port facing
up, lay tool on its side.
STEP 5:
Install Fill Bottle in
Reservoir Fill port. (Figure 11)
STEP 6:
Connect tool to shop
air 20-40 psi. Cycle tool 20-30
times, watch for air bubbles
escaping from the tool into
bottle. (Tool may be rocked to
free trapped air.) Do not allow
the air to re-enter the tool.
When cycling tool, always hold
bottle up as shown in Figure 10
to prevent drawing in air from empty part of bottle.
STEP 7:
When air bubbles no longer appear in bottle,
remove Fill Bottle and replace the Reservoir Fill Plug
while
tool is lying on its side
.
STEP 8:
Install the Check Valve Ball, Guide and Spring.
Replace the Check Valve Plug.
STEP 9:
Turn tool so front of head faces you. Prior to
removing Relief Valve Plug, using a 3/32 Allen wrench,
back out setscrew inside of the plug approximately 1/2
turn counterclockwise. This ensures that the Piston will
remain in full-forward position. Remove the Relief Valve
Plug, install Ball, Guide, Sleeve and Spring, and replace
the plug.
STEP 10:
Unlock Fill Tool and check Reservoir red line.
Cycle the tool the with Stall Nut attached and Retaining
Nut locked in the full-forward position (“Dead Stall”).
Reservoir should not drop below the red line on the
Reservoir housing.
STEP 11:
Re-lock the fill tool. Lay tool on its side and
remove Reservoir Fill Plug. Top off Reservoir by placing
a few drops of oil in hole and waiting for air bubbles to
escape. Push a pin or scribe into hole to check for trapped
air bubbles. Replace Plug.
STEP 12:
Unlock the Fill Tool and cycle tool as in step
10. Reservoir may drop slightly. If so, repeat step 11 until,
when the Fill Tool handle is touched, it has no pressure
against it and it drops out of the lock position, and the
Reservoir Plunger does not drop when tool is cycled.
NOTE: This usually requires 3 to 4 times topping off.
STEP 13:
Remove Fill Tool and Stall Nut. Install a nose
assembly and pull several fasteners to test function.

WARNING:
Avoid contact with hydraulic fluid.
Hydraulic fluid must be disposed of in accordance
with Federal, State and Local Regulations.
WARNING: Failure to re-lock Fill Tool will result
in oil being ejected from the head under pressure
during the topping off of the Reservoir. Severe
personal injury may result.
WARNING: Air pressure MUST be set to 20 to 40 psi
to prevent possible injury from high pressure spray.
If Check Valve Plug is removed, Fill Bottle must be
in place before cycling tool.
