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 period,
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:
SECTION 7
MAINTENANCE INFORMATION
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.

Mechanical brake inspection procedure

With the firewall removed, inspect both brake caliper assem-
blies.

7.3.2 BRAKE CALIPER ADJUSTMENT

Adjust the calipers when:
•
the brake adjustment nuts are tightened all the way but the
steering lever travel still exceeds 18cm (7") or
•
the total clearance between the brake pads and the brake
disc exceeds .010".
To adjust the brake calipers:
1. Tighten the lock nut with a 1/2" open end wrench, no wider
than the thickness of the lock nut (Figure 7-21). As the
lock nut is tightened, measure the clearance between the
brake disc and pad as shown in Figure 7-23, using a .010"
feeler gauge. .010" is the correct clearance between the left
