ACCESSORY INFORMATION
2. Apply a drop of blue 242 Loctite to the hole in the lock
bushing and the set screw. Install the set screw using a 1/
8" Allen wrench. TIGHTEN SECURELY. Set screw must
seat in ground recess of track pin.
3. Assemble two complete tracks:
6 wheel models - 29 segments each side for V699 models
& 28 segments each side for all previous
models
- 1 half segment
8 wheel models - 36 segments each side
- 1 half segment
IMPORTANT: The actual number of track segments
used will vary and will be determined when the tracks
are being installed. Wrap the track assembly around
the tires. Ensure they are snug to the front and rear
deflated tires. Then add or remove segments until there
is a gap of approximately 2" to 2-1/2" between the ad-
joining segments. These will have to be drawn together
using two C-clamp style vise grips to install the con-
necting pin.
If the tracks, when laid on the ground, appear to curve
to one side, then turn one set so that they curve in oppo-
site directions, as shown in Fig. 11-3. If this is NOT
done, the vehicle may pull to the left or right during
straight line operation.
Figure 11-3 Track Assembly
4. Lay the two assembled tracks on the ground. Drive the
vehicle forward onto the tracks until only two segments
are in front of the tires.
5. Pull the remaining track around the rear tire and forward to
the front of the vehicle.
6. Deflate the front and rear tires for easier installation of the
final track pin. The gap between the adjoining segments
should be between 2" to 2-1/2". Adjust the quantity of
track segments to meet this requirement.
7. Join the two ends of the track and secure them in place
with C-clamps as shown in Fig. 11-4, so that the 1/4" holes
are lined up.
8. Install the final track pin as in instruction No.1 & 2. Re-
move the C-clamps.
9. Inflate all tires to 3.0 psi (0.17kg/cm2).
Figure 11-4 Track Assembly
10. Allow the tires to reach temperature of operating condi-
tions. Recheck the tire inflation at operating condition be-
fore operation.
Temperature changes will cause the segments to expand or
contract and will also change the tire pressure. In order to
maintain suitable tension on the track system, observe the
following precautions:
DO NOT over inflate tires. Lower body damage could
result from track segments rubbing against the
polyethylene body material. Pay special attention to
the tracks during the first few “run-in” hours of use.
If the tracks become slack, start hitting the lower body,
or the tires begin to slip inside the tracks, DO NOT
INCREASE TIRE PRESSURE OVER 3.0 psi. RE-
MOVE THE HALF SEGMENT FROM EACH
TRACK, OR REMOVE A FULL SEGMENT AND ADD
THE HALF SEGMENT.
Over inflation of the tires will cause excessive and pre-
mature wear of the tires and ARGO track system, and
may cause axle and/or axle bearing damage. Under
inflation of the tires may allow them to slip in the track
or may cause the tire to pop off the wheel rim. Under
