THE STEERING
To adjust the mesh of the worm and sector, slightly loosen the three
nuts (I) and the lock-nut (4) and turn screw (3) clockwise to take up slack.
Tighten the screw' and lock-nut and test for mesh. This adjustment
~hould be carried out with the road wheels in the straight ahead position.
{)n this type of steering there is the minimum back-lash in the straight-
"head position, the back-lash increasing towards the full lock.
Before dismantling the steering it is important to disconnect the
<:ontrol wires and loosen the clip at the bottom of the steering column.
A special guide is necessary for re-assembly.
These adjustments should be made by an Austin Dealer.
Adjustments of the Track Rod and
Steering Box
A
LTHOUGH adjustments to the steering mechanism are not difficult,
considerable experience is necessary before they should be under-
taken and we strongly recommend that such work should be done
only by Austin Dealers. .
The steering should he checked by an Austin Dealer once or twice
a year.
The Steering Box.
The steering box of the Austin "Seven" is of the "hour-glass"
worm and sector type. .
Facilities are provided to adjust end play at the worm, end play in
the steering cross shaft, and also the mesh of the worm and sector.
To take up end play at the worm, remove the end cover by taking
out screws (2). With a knife blade separate and remove ooe or more.
of the thin shims. Replace the end cover and test for end play, removing
further shims if necessary.
To take up end play at the steering cross shaft, remove the shaft
and add one or more shims, as required.
Tracking Adjustment.
One of the causes of premature tyre wear is the front wheels being out
"f track.
'The wheels, if they are correctly tracking, should not be parallel,
but should be t in. closer between the rims in front of the axle than they
"re behind. This difference, or "toe-in" as it is called, allows for working
<:learances of the steering connections and any slight spring of the parts,
~o that when the car is running the wheels are as near parallel as possible.
If this difference is greater or smaller than tin. the tracking should be
<idjusted. This is not difficult to effect. It is necessary to remove the
<:fosstube lever, on the near side, from the swivel axle.

It is secured by a nut on the front of the swivel axle, under which
there is a spring washer. With this done, the steering cross tube is freed
.at the near side for the adjustment. On the clamping bolt of the steering
"rm jaw being slackened, the jaw can be screwed further on, or off, the
<:rosstube, for so many complete turns as may be necessary. This move-
ment will enable the correct adjustment to be attained. Then the clamping
bolt,is re-tightened. On refitting the cross tube lever to the axle, tighten
the nut securely, with the spring washer under it.
This adjustment should be made by an Austin agent who is properly
.,quipped for the work,
