INSPECTION

Wheel
balance

The
wheel
and
tire

assembly
should
be

kept
balanced

statically
and

dynamically

Proper
tire
balance
is

necessary
when

driving
the
car
at

high

speeds
Consequently
the
wheel
and
tire

assembly

should

be

properly
rebalanced
whenever

puncture
is

repaired

The
wheel
and
tire

assembly
becomes
out
of
balance

according
to
uneven
tire
wear

Severe
acceleration
and

braking
or

fast

cornering
is
the

cause
of
wear
on
tire

resulting
in
unbalance
of
tire
and
wheel

assembly

The

symptom
of

unbalance

appears
as

tramp
car
shake

and

steering
trouble

To
correct
unbalance
use

wheel

Wheel

In
order

to
ensure

satisfactory
steering
condition
as

well

as
maximum
tire
life

proceed
as
follows

I

Check
wheel
rim

especially
rim

flange
and
bead

seat

for
rust
distortion

cracks
or
other
defects
which

might

cause
air
leaks
Function
of

tubeless
tire

depends
on
a

good
seal
between

bead
and
wheel
rim

Thoroughly

remove
rust

oxidized

from
wheel
rim

with

cloth
or

paper
Use
dial

to

examine

STEERING

DESCRIPTION

The

steering
system
consists

of

recirculating
ball

type

gear
box

and

parallelogram
linkage

These

systems
give
good

response
light
handling
and

utmost
durability
Moreover
the

steering
linkage
is

equipped
with
a
torsion

rubber

system
idler
arm
which

absorbs
shock
from
the

wheel

Check
the
lubricant
of

gear
box

every
10
000

km
6
000
miles
and

replenish
recommended
oil
as

required

The

steering
linkage
should
be

greased
up
with
wheel

bearing
grease
every
50
000
km
30
000
miles

All

necessary
service

procedures
for
the

steering
lock

system
are
described
in
the
