and,
since no

nape
rtu res
are
provided, all
adjustments
have
to
be
carried
out
by
pre-
measurement
in
conjunction
with
special
gauges.
Adjustment
of
the
position of
both
the
crown
wheel
and
the
pinion in
the
axle Is effected by distance-
pieces, which
are
selected on initial assembly, and
there
is no
other
provision for
adjustments.
The
crown
wheel
and pinions
are
only supplied in pairs
as
heretofore.
The
use
of
Hypold gears enables a much larger
pinion
to
be used, provldlng
more
silent running and
a
greatly
increased life.
The
rear
brake
gear
is of
the
normal
two-shoe
type,
operated
hydraulically
from
the
brake pedal and also
mechanically by
hand-operated
mechanism actuating

Adjustment
is by means of a

Suspension is by means of seml-elli ptlc leaf spri ngs

LUBRICATION
Oil is
introduced
to
the
axle
through
a filler plug
on
the
right-hand side of
the
pinion housing.
When
replenishing
or
refilling,
the
level of
the
oil should not
be raised above
the
lip of
the
filling
aperture.

It
is
of
the
utmost
importance
that
only
HYPOID
oils
of
the
approved
grades
and
manufacture
be
employed
if
satisfactory
service
is
to
be
obtained
from
the
Hypoid
gears.
Inspect
the
oil level
every
1,000
miles (1600km.)
and replenish If necessary to
the
level
of
the
filler
opening
with
one
of
the
Hypold oils

After
the
ti
rst
500 miles (800 km.) and
subsequently
every
6.000 miles (10000 krn.)
drain
off
the
old oil
and refill
with
new.

The rear
axle
drain
plug
is situated in the
base

casing.
The
drain plug Is
underneath
the
rear
end
of
the
axle casing.
The
capacity of
the
axle is
2!
pints
(1'3
litres).
Lubrication of
the
rear
hub bearings is achieved
automatically from
the
main oil supply and no
pro-
vision is made for any
other
attention.

REMOVING
AND
REPLACING THE
BRAKE-DRUM
AND
HUB
The
brake-drums
are
permanently
attached
to
the
wheel
hubs by
countersu
nk-headed
screws,
the
in
ner
ends of which
are
riveted
over.
These
screws
should
not
be
disturbed,
and
if
it
is
necessary
to
fit
a
new
drum
or
hub
a
complete
assembly
should
be
used
as
the
hubs
and
brake-drums
are
machined
after
assembly.
On
some
models
the
hub and
drum
are
made
in
one
piece.
Jack up
the
axle so
that
the
wheel
to be
operated
on is
dear
of
the
ground
and place chocks on
either
side of
the
wheels remaining on
the
ground.
