THE STARTER SWITCH
The
starter
switch is fitted on
the
engine side of
the
bulkhead and is
operated
by pulling
the
control knob
in
the
instrument
panel.
The
knob is connected
to
the
switch by means of a cable. At
the
back of t he
starter
switch
are
two
terminals. from
one
of which
two
cables are connected,
the
heavy
one
to
the
battery
and
the
other
to
the
ammeter.
from
the
second
terminal
a heavy cable is
taken
to
the
terminal on
the
commutator
end
bracket
of
the
starter.
When
the
starter
Is
operated,
the
rotatIon of
the
armature
screws
the
pinion along
the
sleeve
to
mesh
with
the
flywheel
teeth.
As soon as
the
engine
starts
firing, it will drive
the
flywheel f
aster
than
it is being
driven by
the
starter.
This will cause
the
pinion co
screw back along
the
sleeve and so
draw
out
of mesh
with
the
flywheel
teeth
. A pinion
restra
ining spring
is fitted
over
the
shaft
to
prevent
the
pinion from
being vibrated into mesh when
the
engine Is running
..
In
the
event
of
the
starter
drive being jammed In
mesh
wlth
the
flywheel, it can usually be freed by
turn
ing
the
starter
armature
by means of a
spanner

COMMUTATOR
AND
BRUSH GEAR
Inspect
the
commutator

the
manner described for
the
dynamo In Sections
NA
and
N.S. The brush spring tension should be 30-40 oz.
(850--1134
grams). This
operation
should be carried
out
every
12.000
miles
or
20000 kilometres.
In
the
unlikely
event
of brush replacement being
necessary. this must be carried
out
by a Lucas Service
Agent, as
the
operation
entails dismantling of
the

This is accessible
by taking off

secured by
two
screws on some models and is a push

on
others.
If
