WHEELS AND TIRES 10-5

WHEELS

The wheel and tire assembly should be removed from

vehicles equipped with disc brakes to properly perform

balancing operations. This is necessary due to drag of

the spring loaded brake shoes on the disc.

Static Balancing (W/Tire)

Static Balance (still balance) is the equal distribution

of weight of the wheel and tire assembly about the axis

of rotation so that the assembly has no tendency to rotate

by
itself.
Static unbalance causes the pounding action of

the front wheels that is called "tramp".

To correct static unbalance (front and rear): The

quickest and best methods to correct static unbalance

are through the use of wheel balancers which are com-

mercially available. Refer to the Information and in-

structions included with these balaricers.

Dynamic Balancing (W/Tire)

Dynamic Balance (running balance) requires the wheel

to be not only in static balance, but balanced and running

smoothly while turning on an axis which runs through the

centerline of the wheel and tire perpendicular to the axis

of rotation.

The quickest and best methods of testing and correcting

dynamic unbalance are by the use of dynamic wheel

balancers which are commercially available. These bal-

ancers include all necessary information on where and

how the balancing weights should be placed. The follow-

ing information, however, will help in the correction of

dynamic balance.

NOTE:
Before attempting to balance the

wheels, check to be certain that no foreign

matter has been trapped in the wheel ventila-

tion slots or in the accessory wheel discs. This

is especially important if the vehicle has been
run in soft mud and then parked in freezing

weather.

When a wheel that is statically unbalanced is dynam-

ically in balance the dynamic balance can be retained

while correcting "the static balance by installing the cor-

rective weights so that half of the weight required is

placed on the inner edge of the rim and the other half

on the outer edge of the rim.

Dynamic unbalance can be corrected without destroying

static balance by installing weights so half of weight

required for dynamic balance is placed on the rim op-

posite the heavy point, while the other half is placed 180°

away and on the opposite side of the rim.

NOTE:
Vehicles with wire wheel covers should

have the wheels balanced with the wire wheel

covers installed on the wheels.

Run Out (W/OTire)

The wheels should not run out (wobble) more than

1/16" as measured on the side of the rim at the base

of the tire. Excessive run-out is the result of a bent

wheel, an improperly mounted wheel, worn knuckle bear-

ings or steering connections. These parts should be

checked for correct adjustment, proper alignment and

wear whenever excessive run-out is encountered.

The wheels should also run concentric with the steering

knuckle spindle within 1/16 inch as measured on the tire

bead seat of the rim with the tire removed.

Wheel run-out, eccentricity and balance are closely

associated with steering and front wheel alignment.

Further information on these subjects will be found under

"Suspension".

Cleaning Aluminum Wheels

Do not use wire brush or abrasive cleaners when

cleaning wheels. Use only cleaners that will not react

with aluminum.

SERVICE OPERATIONS

TIRES

Removal

Dismounting tubeless tires presents no problems if the

correct procedures are used and the following precau-

tions observed.

1.
Remove the valve cap and valve core. Let out all the

air.

2.
Press the inner side of the tire into the rim well.

Use bead loosening tool or if regular tire irons are

used, take particular care not to injure or tear the

sealing ribs on the bead.

CAUTION: Never use tire irons with sharp

edges or corners.

3.
Using tire irons on the opposite side, remove bead,

taking small "bites" around the rim.

4.
Turn the tire over, and use two tire irons, one be-

tween the rim flange and the bead to pry the rim

upward, the other iron to pry outward between the

bead seat and the bead.
Installation

Extreme care must be exercised to prevent injury to

the sealing bead and circumferential bead when forcing

tire over rim.

1.
Apply a light film of Ruglyde or other suitable rubber

lubricant to sealing bead of tire.

NOTE:
The use of excessive lubrication may

lead to rim slippage and subsequent breaking of

air seal.

2.
Carefully mount the outer bead in usual manner by

using tire irons, taking small "bites" around rim,

being careful not to injure the tire bead.

CAUTION: DO NOT use a hammer, as damage

to the bead will result.

3.
Install the inner bead in the same manner.

NOTE:
If a seal cannot be effected in the fore-

going manner with the rush of air it can be

, accomplished by applying to the circumference

of the tire a tire mounting band or heavy sash

cord and tightening with the use of a tire iron.

On tire mounting machines, bouncing the tire

assembly is not required. The tire should be

GENERAL DESCRIPTION

The sturdy front end structure is formed by three

welded assemblies, the left and right hand fender skirts

and the radiator support panel. These units are bolted

together and to the dash panel (fig.
16).

Fender skirts, containing spring towers and support

brackets for control arms, are welded to the reinforced

"closed hat section" side rails. The skirts and rails

are fastened at top and bottom to reinforced areas of the

dash panel. Each skirt and rail assembly is securely

mated ta the body with three bolts at the top, and at the

stub fr|.me butt plates with a four bolt series. Heavy

gauge, formed, reinforcing plates receive the top of the

fender skirt and provide a shimming surface for precise

alignment of front end and body when assembled.
The one-piece radiator support panel completes a box

section when welded to the front crossmember. The

panel is formed to add structural strength and rigidity.

This strong combination is bolted along the full length of

each forward vertical edge of the fender skirts and at

the stub frame ends. Additional strength is obtained from

rigid diagonal corner braces. These open hat section

braces, bolted to side rails and front crossmember,

provide mountings for the suspension tension struts.

Conventional front fenders, grille, bumper and brack-

ets all bolt on to the unit front end structure. The hood

is connected to the front end with hinges that are attached

to the fender skirts.
