TIRE MAINTENANCE Mounting

Wheel Nuts Tires are to be r epaired only by an authorized person

using the proper procedures and safe equipment.
Check the wheel nut torque at the correct service
interval. (See SERVICE SCHEDULE on Page PM-5.) Tires and rims must always be checked for correct size
before mounting. Check rim and tire bead for damage.
The correct torque is 50-55 ft.-lb. (68-75 N•m).
The rim flange must be cleaned and free of rust.
Tire Rotation
The tire bead and rim flange must be lubricated with a
Check the tires regularly for wear, damage and pressure. rubber lubricant before mounting the tire.

Avoid excessive pressure which can rupture the tire and

cause serious injury or death.

IMPORTANT During inflation of th e tire, check the tire pressure

frequently to avoid over inflation.
Inflate tires to the MAXIMUM pressure shown on the
sidewall of the tire. DO NOT mix brands of tires used
on the same loader.
I-2057-0794
WARNING
Figure PM-45

Dealer Copy -- Not for Resale

Do not inflate tires above specified pressure. Failure
to use correct tire mounting procedure can cause an
explosion which can result in injury or death.
W-2078-1285

B-9976

Rear tires usually wear faster than front tires. To keep tire
wear even, move the front tires to the rear and rear tires
to the front [Figure PM-45].

It is important to keep the same size tires on each side of

the loader. If di fferent sizes are used, each tire will be
turning at a different rate and cause excessive wear. The
tread bars of all the tires must face the same direction.

Recommended tire pressure must be maintained to avoid

excessive tire wear and loss of stability and handling
capability. Check for correct pressure before operating
the loader.
