To check Ackerman angles
Prepare the car as described in "Preparation of
vehicles", THIS IS IMPORTANT. Check the front
wheel camber angle, front wheel alignment and
correct as necessary.
Set the front wheels in the straight ahead position
on two turntable gauges. Level the car by raising
the rear wheels with packing pieces the same
thickness as the turntable gauges.
Move the right hand front wheel through a 20
°
turn to the left and note the gauge reading of the
turntable gauge under the left hand front, wheel.
Move the left hand front wheel through the 20
°
turn to the right and note the gauge reading of
the turntable gauge under the right hand front
wheel.
When these gauge readings are outside the speci­
fied "Inner wheel" figure given In the "General
Data Section", one or more of the following faults
can be suspected which must be corrected.
(a) The outer track rod lengths are not correctly
set. They should be adjusted as described in
earlier paragraphs under "Setting of Outer
Track Rods".
(b) A track rod is bent.
(c) A steering arm or arms are bent.
Fig. 7 gives the correct dimensions of the steering
arm.
Bent parts should be renewed as it is not advis­
able to straighten them.
Wheel lock angles-To adjust
Set the front wheels In the straight ahead position
on two turntable gauges. Move the right
hand front wheel through a 24
°
turn to the left.
Adjust the lock stop, located on the top face of
the lower link trunnion, on the LEFT hand side
of the car. The bolt must be slackened off and
the eccentric disc beneath its head rotated until
It contacts the stub axle lug and retighten the
bolt.
Move the left hand front wheel through a 24
°
turn to the right.

CASTOR, CAMBER and STEERING AXIS
INCLINATION ANGLES
To check
IMPORTANT-The vehicle must be loaded on to gap
gauges as described under "Preparation of Vehicle".
Application of the Weaver gauge
(See Figs. 8, 9 and 10)
Loosely assemble the adaptor clamp, spring and
sleeve into the bracket of the gauge. Wipe away
grease from spindle nut and thrust washer.
Ensure that split pin ends do not overlap thrust
washer face. Secure the adaptor clamp to the
spindle nut by locating the clamp point and tapered
adjusting screw In opposite castellations. Finally
tighten the knurled adjusting screw.
Hold the gauge and adaptor sleeve against the
bearing thrust washer, making sure that the sleeve
Is centred on the washer.
