Track adjustment
Centralise the steering by turning the steering wheel from lock to
lock, counting the turns necessary, then turning back exactly half
the number to ensure the steering box is fully centred. The
steering wheel spokes should be in a horizontal position.
Using Dunlop or similar wheel alignment equipment measure the
front wheel alignment. If adjustment is required slacken the outer
tie rod lock nuts and turn the tie rods until the correct alignment
is obtained. Take one reading, roll the vehicle forwards so the
wheels rotate 180°, then obtain a second reading and adjust the
rods to the mean of both readings. This compensates for any
wheel rim run out.
Castor and camber adjustment
The following instructions for measuring caster and camber are
applicable to the Dunlop instruments. Other types of measuring
equipment will be equally effective.
The caster angle is 4° and the camber angle 0-1/2° positive (
Figure
4 )
To measure camber
Check that the vehicle is on a level surface, that the front wheels
are pointing straight ahead and that the tyres are correctly
inflated.
The level of the floor should be checked with a Dunlop CG/4
camber gauge (
Figure 5 ) by placing the gauge on the floor in the
direction in which it is desired to check the floor level, adjusting
the dial (B) to centre the bubble in the spirit level (C). The angle of
inclination is read from the scale on the dial (D).
If a level floor is not available it is possible to work on a small
slope and correct the camber reading by adding or subtracting the
measurement of floor inclination.
Apply the long edge of the gauge to the tyre wall, holding the
gauge upright but avoiding the part of the tyre that bulges due to
load. A small departure of the gauge from absolute vertical will
not affect the reading. Adjust dial (A) until bubble in level (D) is
central, read camber out or in from the scale in dial (A).
The amount of camber should be 0° to 1/2°. If this reading is not
obtained, shims should be added or deleted equally to both the
right and left hand fulcrum fixing bolts until the correct camber
angle is achieved.
To measure castor angle
Check that the vehicle is on a level surface, that the front wheels
are pointed directly ahead and that the tyre pressures are correct.

Figure 5 Camber gauge
Follow the same procedure for checking the floor as for measuring
the camber angle and if necessary make corrections to the caster
angle.
Using Dunlop CG/6 turntables and run-on ramps, place one
turntable with locking pin in place in front of the centre of each
front wheel with run-on ramps at the rear of the turntables.
Place the other ramps in front of each rear wheel so that the back
of the car will be raised to the same height as the front.
Drive the car on to the turntables with the locking pins in position
so that the centres of the front wheels are over the centres of the
turntables.
Attach the special clamp (F
igure 6 ).
Remove the locking pins and check there is free movement of the
turntable plates (fore, aft and laterally).
Fit the Dunlop CG/5 gauge with caster dial to the left of spindle (E)
and secure with knurled nut (Figure 7).
The gauge should be set to approximately horizontal. Set
turntable scales to zero.
Steer the wheel 20° IN, i.e. Right-hand wheel steered to the left or
left-hand wheel steered to the right as viewed from the driving
position.
Set the castor dial on the top to zero (Figure 7).
Centre the bubble in the level (E) by turning the lower knurled
screw.
Centre the bubble in the level (F) by turning the lower knurled
screw (H).
