Assembly
This procedure is for the assembly of the tool. For
component identification, see Figures 9–13.
BEFORE RE-ASSEMBLING THE TOOL:
• Clean components with mineral spirits or a similar
solvent. Inspect for wear/damage and replace as
necessary.
• Replace all seals, wipers, and rings of disassembled
components.
• Use the O-rings, Quad-rings, and Back-up rings
from
the appropriate Huck Spare Parts Service Kit (P/Ns
2013KIT
,
2013BKIT
,
2013VKIT
, or
2014KIT
).
When assembling the tool, take care not to damage
O-rings, Quad-rings, Back-up
rings.

mating parts to ease assembly.
TO RE-ASSEMBLE THE TOOL:
1. Assemble gland assembly. Replace Polyseal, spacer,
and retaining ring.
NOTE
:
Note the orientation of the Polyseal in the
appropriate Assembly Drawing in this manual.
2. Thread the Polyseal Insertion Tool (P/N
121694-202
)
into the handle assembly.
3. Push front gland assembly, except for wiper seal, onto
piston. Then slide the wiper seal onto the piston.
4. Gently push the assembled components into the
handle assembly from the rear using a press, or a soft
mallet and wood or brass drift.
5. Remove the Polyseal Insertion Tool.
6. Model
2014
: (Figure 13) Place spring into the back
end of piston, and install end cap into the handle
assembly.
2013
Series: Place pintail extension tube into the back
end of piston. Assemble rear wiper seal, spacer (where
applicable), and spring in end cap, and install into
handle assembly.
2013
: (Figure 10) Install pintail deflector.
2013B
: (Figure 11) Install pintail collection bottle
by sliding it over the back end of end cap. Reach
through hole in the pintail bottle and install washer
and retaining ring.
2013V
: (Figure 12)
i. Install O-ring, washer, wiper seal, tube, and
retaining ring into the back of end cap. (Figure 12,
section A-A)
ii. Press slide onto the back end of the end cap
until it is fully forward. Note the orientation in
Figure 12.
iii. Place adapter and pintail collection bottle over
the slide and the
end cap; secure with washer and
retaining ring.
7. Position cable assembly in trigger slot and push
trigger 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 timing pin maintains the
orientation. (Figure 9)
9. Apply Loctite
®

™
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 rod assembly
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 assembly squarely into the cylinder,
taking care not to damage O-ring. Install retaining
ring; align the screw holes with bottom plate.
13. Carefully position bottom plate
on the cylinder,
making sure that it is properly positioned in the recess
of the bottom plate. Secure the muffler end cap with
three button-head screws using a 1/8” hex key.
14. Place the tool upright on a level surface. Drop spring
into the throttle valve hole in the cylinder, and push
throttle valve assembly into the cylinder.
15. Place the ball end of cable assembly in the end of
throttle arm. Slide the throttle arm into slot on the
cylinder.
16. Insert pivot screw into the cylinder to retain the
throttle arm.
The tool is now assembled and must be filled with
hydraulic
fluid prior to use. See the
Fill and Bleed
section
. Install the bleed plug and O-ring assembly after
that process.
