Steering Box Question

[Robert Leigh]

The type of steering box in the picture is adjustable, as evidenced by the slotted holes in the side through which the drop arm pivots. The internal gear has three keyways so that it can be repositioned when wear becomes a problem. Clearance between the worm and the gear should be adjusted when the wheel is at full lock, checking both extremes, because the centre part of the gear sector in use wears more than the ends. If you do not do this the steering goes stiff in anything but the centre position. With Austin Sevens a little play is preferable to stiffness.
