WHEEL CAMBER
To check, using the Churchill camber gauge
(See Figs. 11 and 12)
The correct wheel camber angle is given in the
Data Section.
Jack up car and check each front wheel for 'run-out'
(see "Preparation of Vehicle").
After lowering the front of the car, and removing
the Jack, and having set the wheels in the required
position, the car must be rolled backwards two or
three yards in a straight line and then forward
until the front wheels are again in the required set
position.
Apply wheel camber checking gauge to the wall

of the tyre, ensuring that the contact points
of the gauge to the tyre are clear of the normal
bulge of the tyre, above the contact area of
the tyre to ground. When using the Churchill
Camber Gauge VLC.121 L, check the camber angle
by moving the slide until the bubble registers
accurately between the two indicator marks on the
spirit level glass; then note the camber reading in
the camber scale, indicated by the scribed line on
the slide (see Fig. 11).
For camber readings the indicator carrier may be
used either side of the main pillar of the gauge,
I.e., 180
°
apart.
Regardless of which side of the main pillar the
Indicator happens to be, the camber reading will
be positive If, in order to bring the bubble between
the Indicator marks, the slide is moved towards
the road wheel side of the zero mark (see Fig. 11).
If after checking It is found that the camber angle Is
Incorrect, no
adjustments should
be
made until the
castor and king pin Inclination angles have also
been
checked.
This Is because a bent stub axle carrier or other
damaged part can be the cause of incorrect camber
angle.
To check the accuracy of the camber gauge
VLC.121 L hold the instrument against any known
upright and take two readings, one with the spirit
level carrier on the right-hand side of the pillar and
the other reading with the carrier on the left-hand
side of the pillar. If the two readings do not agree,
then the instrument has suffered damage and a
correction will have to be applied to all future
readings or the Instrument returned to the makers
for rectification.
STEERING AXIS INCLINATION
To check
The correct steering axis inclination is given
in the Data Section.
It Is important that the camber check Is carried out
before making a check of the steering axis Inclination
