7.2.6 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 3.5 psi
(24 kPa), 5 psi (34.5 kPa) maximum operating pressure. A
special, low pressure tire gauge (Part No. 619-10) is avail-
able from your CENTAUR dealer.
Replace badly worn or damaged tires with original equip-
ment Goodyear tires. Consult your CENTAUR dealer if in
doubt. Any other tires (size, type or tread pattern), will affect
the skid steering characteristics of the vehicle.
7.3 MECHANICAL PARKING/EMERGENCY
BRAKE
7.3.1 GENERAL
Periodic inspection and adjustment of the parking/emergency
brake system is required to maintain performance.
Figure 7-11. Mechanical parking/emergency brake
7.3.2 BRAKE CALIPER ADJUSTMENT
With the engine cover and transmission cover removed, in-
spect the mechanical brake caliper assembly.
Adjust the calipers when:
•
the brake adjustment nuts are tightened all the way but
the parking brake cannot be firmly engaged using the
parking brake lever, or
•
the total clearance between the brake pads and the brake
disc exceeds .010".
To adjust the brake caliper:
1. Tighten the lock nut with a 1/2" open end wrench, no
wider than the thickness of the lock nut (Figure 7-12).
As the lock nut is tightened, measure the clearance be-
tween the brake disc and pad as shown in Figure 7-13,
using a .010" feeler gauge. .010" is the correct clearance
between the left brake pad and the brake disc when the
right pad is pressed against the disc.
2. Use another 1/2" open wrench to tighten the outer lock
nut to the inner one.
3. Tighten the adjustment lock nut with a 1/2" wrench so it
is snug but the bolt can still be turned freely with fingers.
