If any difficulty
is
experienced
in removing
the
nuts
with
the
wheel-
brace,
eitra
leverage
can be
applied
by using
the
l"
spanner,
provided
in the
tool
kit, on
the
squared
section
of
the wheel-brace
spanner
head.
Wheel
Discs.
When
fitting the wheel discs,
care
must be taken
to
get
the
valve
centred
in the
hole
provided.
The
outer
nuts, having right-hand
threads
for
both
"off-side
and
near-side"
wheels, are
neCessary
only to
retain
the
disc
and should
therefore
not be
overtightened.
The
correct
tension
is attained
by
giving
the
nut
one
complete
turn,
with the special
spanner
provided,
after the disc
has
been
felt
to
be
in light contact
with the
rubber stops
on the
wheel
centre.
There
should be
a
small
gap,
approximately
'roo",
between
the
edge
of
the disc
and the wheel.
Overtightening
distorts
and
brings
the
disc
into contact
with the wheel,
thus
causing
creaks
and
rattles.
Lubrication
of
Wheel Bearings.
The
wheel bearings
are
correctly
packed with
ball-bearing
grease
in the
first
instance,
and
should
need
no
attention
between
general
overhauls
of
the
chassis.
Tyres,
The
tyres
fitted are India
Super
Silent
Rayon, size
6.5o" by
t6'.
When
ordering
new
covers,
the
above
should
be specified.
With
regard
to
the
innel
tubes,
it is
necessary
to state
the size
and mention
"well-base".
Tubes
for
flat
base
rims
should
not be
used.
