REMOVING
AND
REFITTING
THE
OIL
COOLER
To
gain access
to
the all cooler, all pipe clips, and
Axlngs,
the
gas tank should be removed (Section
E1
).
Unscrew
both all pipe clips and note
that
the
left
hand
pi
po'
from the cooler leads
to
the
rocker
feed
pipe.
After
removel of the pipes,
ensure
that
the
cooler
Is
not
tilted, since
It
contains
over
half a
pint
of
all.
Slacken
two
suppOrt bracket
top
bolts sUfficiently
to
allow eight
corner
packlngs
to
be

Oil.cooler
mountings
Whilst
supporting
the
c~oler,
remove
the
suppOrt
bracket
bolts, nuts and washers, and collect four
solgotted
rubber
washers.
The
cooler
Is
now free of the frame and should be
removed
and drained
by
Inverting above a suitable
container.
I
Do
not
attempt
to
flush
out
the
Inside of
the
cooler,
since
little
or
no foreign
matter
Is
collected. How-
ever,
It
Is
advisable
to
wash
the
outside
with
kerosene
(paraffin) and a soft brush.
To
refit, assemble
the
support
brackets as shown
(Fig. A7), and note
that
the
large all pipe unions
on
the
top
of
the
cooler are Inclined rearwards.
Suspend
the
cooler
on
the
frame using
splgotted
rubbers
and bolts as shown (Fig. A7).
Secure
both
brackets
to
the
frame, and replace both
large
diameter
all pipes.
The
left side union
connects
to
the
scavenge pipe, I.e.
the
pipe which
connects
to
the
metal
rocker
reed pipe union.
Tighten
the
union clips ensuring
that
the
pipes
are
not
damaged by over tightening.
Refit
the
gas tank
as
In
Section
E1.
Note
that
where
reflectors are fitted,
their
rubber
backings
are
attached
to
the
all cooler
by
a suitable
adhesive.
SECTION
A9
REMOVING
AND
REPLACING
THE
ROCKER
OIL
FEED PIPES
To
disconnect
the
rocker all feed pipe for removal,
the
two
domed nuts should be removed from
the
ends
of
the
rocker spindle, and
the
banjos
with-
drawn.
Disconnect the rocker all feed pipe from
the
scavenge/all cooler pipe. Dismantle
the
flexible
pipes and connections to the
rocker
spindle. Drain
the
pipes into
an
oil tray.
Care
should
be
taken that
the
metal
pipes
are
not
bent
exce5sively
because
this
might ultimately
result
In
a fracture. When removed,
the
feed pipes
A10
should
be
thoroughly cleaned
In
kerosene (paraffin)
and
checked
for
blockage with
the
aid
of
a Jet
of
compressed air.
When
refitting
the
feed pipes, It
Is
advisable
to
Use
new
copper
washers, but
If
the
old
ones
are
annealed
they
should give an effective all seal.
Annealing
is
achieved
by
heating
to
cherry
red
heat
and
pi
u
ngl
ng
I
nto
water. Any scale
that
Is
formed on
the
washers
should be removed prior
to
re-fittlng
them.
