This procedure is for the assembly of the tool. For
component identification, see Figures 4–7.
BEFORE RE-ASSEMBLING THE TOOL:
•
Clean components with mineral spirits or a similar
solvent. Inspect for wear/damage and replace as
necessary.
•
Use the O-rings, Quad-rings, and Back-up rings
from the appropriate Huck Spare Parts Service Kit
(P/N
2015KIT
or
2015VKIT
). When assembling the
tool, take care not to damage O-rings, Quad-rings,
Back-up
rings.

and mating parts to ease assembly.
IF THE BUSHINGS WERE REMOVED FROM THE
CYLINDER:
•
Use an arbor press and apply Loctite
®
#609,
(503377) on the bushings before pressing them into
the cylinder. Place the chamfered end of the upper
bushing in the top of the cylinder. Carefully press
the bushing squarely into the cylinder. Repeat the
procedure for the lower bushing.
TO RE-ASSEMBLE THE TOOL:
1. Assemble the gland assembly. Replace the
Polyseal, spacer, and retaining ring. Install the
adapter into the cylinder handle/head.
NOTE
:
Note the orientation of the Polyseal in the
Assembly Drawings in this manual.
2. Thread the Polyseal Insertion Tool (P/N
121694-
202
) into the handle assembly.
3.
Thread the Piston Assembly Tool (P/N
123111-
4
), onto the piston assembly. Push the front gland
assembly (except for wiper seal) onto the piston.
Then slide the wiper seal onto the piston.
4. Use a press, or a soft mallet and wood or brass
drift, and gently push the assembled components
into the handle assembly from the rear.
5. Remove the
Piston Assembly Tool and
Polyseal
Insertion Tool.

7. Position cable assembly in trigger slot and push
the dowel pin through holes in trigger and cable
assembly. Position assembled trigger in handle and
drive roll pin through holes in handle and trigger.
8. Secure the handle assembly upside-down in a soft-
jaw vise. Place the inverted cylinder assembly on
the base of the handle. The cylinder pin maintains
the orientation.
9. Apply Loctite
®
243
™
to the threads of the gland
assembly. Screw the gland assembly into the
handle assembly. Use a 1-3/8” socket wrench to
tighten and torque to 36–66 ft.-lbs.
10. Push the bumper firmly over the gland. (The slots
must face the bottom of the tool.)
11. Clean the piston rod threads and apply Loctite
®
243
™
. Carefully press the assembled air piston and
piston rod into the cylinder just enough to allow
installation of the cylinder head assembly.
12. Secure the head upside-down in a vise. Push the
cylinder head squarely into the cylinder, taking care
not to damage O-ring. Install the retaining ring; align
the screw holes with the muffler end cap. (Figure 6)
13. Position muffler in the center of the cylinder head.
Position the gasket on the cylinder assembly, taking
care to note the direction of the lip in Figure 6.
14. Carefully position the muffler end cap on the
cylinder, making sure that it is properly positioned in
the recess of the bottom plate. Secure the muffler
end cap with the three button head screws using a
1/8” hex key.
15. Place the tool upright on a level surface. Drop the
spring into the throttle valve bore in the cylinder,
and push the throttle valve assembly into the
cylinder.
16. Place the ball end of the cable assembly in the
end of throttle arm. Slide throttle arm into slot on
cylinder.
17. Insert the pivot screw into the cylinder to retain the
throttle arm.
18. Screw anvil insert into anvil holder. (Figures 4 & 5)
19. Assemble the collet with all necessary components,
and screw the assembled collet onto the piston rod;
tighten securely.
20. Screw the anvil holder into the adapter.
The tool is now assembled and must be filled with
hydraulic
fluid prior to use. See the
