SECTION 7
MAINTENANCE INFORMATION
Replace badly worn or damaged tires with original equip-
ment Goodyear tires. Consult your ARGO dealer if in doubt.
Any other tires (size, type or tread pattern), will affect the
skid steering characteristics of the vehicle.
ARGO track systems are designed for use ONLY with origi-
nal equipment Goodyear Runamuk tires.
7.2.8 AXLE BEARING MOUNTING
The axles are mounted to the Argo using special cork gas-
kets between the flanged bearings and the outside surface of
the lower body (see Figure 7-18). During the initial run-in
period, the gasket material may relax causing the nuts to
loosen slightly. These should be checked and re-tightened
after initial 8 hours of use and then after every 100 hours.
See Figure 7-19.
7.2.6 TIRE INFLATION
Improperly inflated tires can cause the vehicle to pull to one
side, requiring constant steering correction. Suggested in-
flation for the Runamuk 22x10.00-8, Rawhide III 22x11.00-
8 and Rawhide III 25x12.00-9 is between 2.5 to 3.5 psi (17
to 24 kPa). Maximum operating pressure is 5 psi (34 kPa).
A special low pressure tire gauge (ARGO Part No. 619-10)
is available from your ARGO dealer.
7.2.7 TIRE REPAIR AND REPLACEMENT
Repair a flat tire by removing the tire completely from the
rim. Proper tire changing equipment is necessary to remove
and remount the tire.
Apply a radial tire patch on the inside of the tire over the
puncture or hole.
Remount the tire on the rim using ONLY WATER as a bead
lubricant. Spoon the tire onto the rim to prevent tire bead
area damage. THE TIRE MAY EXPLODE IF OVER-IN-
FLATED. Place the tire and rim assembly in a protective
cage to inflate and to seat the beads. Never inflate over 32
psi (220 kPa) to seat the bead. Once both beads are seated,
deflate to 2.5 to 3.5 psi (17 to 24 kPa), 5 psi (34 kPa) maxi-
mum operating pressure. A special, low pressure tire gauge
(ARGO Part No. 619-10) is available from your ARGO dealer.

7.3 MECHANICAL BRAKES - 6x6 VANGUARD
7.3.1 GENERAL
Periodic inspection and adjustment of the mechanical brake
system is required to maintain optimum vehicle performance.
Inspect the brake pads after every 25 hours of use. Badly
worn pads can lead to brake disc damage. To inspect the
pads, first remove the firewall:
To remove the firewall:
1. Remove the front floor pan.
2. Remove the left and right brake adjustment nuts with a
1/2" deep socket and ratchet (refer to Section 1.6).
3. Pull both steering levers back, away from the dash and
against the seat.
