7.2.6 TIRE INFLATION

Improperly inflated tires can cause the vehicle to pull to one
side, requiring constant steering correction. Suggested infla-
tion 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-INFLATED.
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) maximum operating
pressure. A special, low pressure tire gauge (ARGO Part No.
619-10) is available from your ARGO dealer.
Replace badly worn or damaged tires with original equipment
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 gaskets
between the flanged bearings and the outside surface of the
lower body (see Figure 7-18). During the initial run-in pe-
riod, the gasket material may relax causing the nuts to loosen
slightly. These should be checked and re-tightened after ini-
tial 8 hours of use and then after every 100 hours. See Figure
7-19.

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. Turn the firewall release catches (located at the top right
and left side of the firewall) counter-clockwise 1/4 turn.
3. Pull both steering levers back, away from the dash as far
as possible.
4. Pull the top of the firewall back and lift it out of the vehi-
cle.
