HORN RING, COVER AND MOTIF
ASSEMBLY
Description
The horn ring consists of a circular central plate
with two spokes, to which the outer ring is joined.
The horn ring Is secured to the underside of the
centre cover by three screws. The upper and
lower contact plates are connected to each other
by studs and nuts, but are held apart by three light
springs. The whole unit Is retained In the hollow
centre of the steering wheel boss by three grub
screws clamping on to the lower contact plate.
The lower contact plate is earthed by the grub
screws to the steering column, via the splined
centre of the steering wheel boss. A wire from
the horn Is attached to an insulated terminal on
the direction indicator switch feeding a spring­
loaded plunger which is in constant contact with
a slip ring recessed into the lower face of the
steering wheel centre boss. From this slip ring
a wire with a snap connector feeds the upper con­
tact plate. For further wiring details see Section N.

STEERING UNIT
Description (See Figs. 1 & 2)
The unit is known as the "F" type recirculating
ball unit.
Movements of the inner column and worm (23),
are transferred to the nut (14), through the medium
of recirculating balls (16) housed within the nut.
Movement of the nut Is transferred to the rocker
shaft arm (13), which causes the rocker shaft to
rotate and turn the drop arm (swing lever), (19),
which is secured to the rocker shaft by a tapered
spline, a nut and lock-washer. A felt bush and
washer (1), are fitted at the upper end of the steering
column (2). Ball bearings (15 & 20), fitted at each
end of the worm, support the Inner column (23),
inside the steering box (9). Shims (4) control the
Inner column end float. The rocker shaft Is
located by the top cover (8), end float being
controlled by shims (5). A double coil spring
(10) and damper button (11), serve to damp the
rocker shaft against road reaction.
