cold. The ring should
be
immersed in
boiling
water or its temperature raised
by sQme other means
;
a temperature
higher than

water is not re-
commended for the heat properties of
the ring may
be
destroyed. The ring
must
be
fitted with the leading edges
of the teeth toward the starter motor.
Should a press not
be
available, fitting

the
ring gear
can be
carried out
using four
"G"
clamps and tapping the

Ventilation
(Fig. 11) is
effected by permitting air to be drawn
out of the engine.
To enable this
ejection a large bore pipe in the form of
an inverted
"U"
is fitted into the left-
hand side of the cylinder block by
means of an adapter welded to its end.
The exposed end is cut away at an
angle to provide a wider opening
facing away from the slipstream.
The passage of air
(the slipstream)
created by the cooling fan or the
movement of the car causes a depres-
sion at the angle opening of the in-
verted
"U"
pipe and air is drawn out
of the cylinder block.
Fresh air is taken in through the rocker
cover oil filler cap, circulating round
the valve springs and rockers before
passing down the push rod tubes into
the cylinder block to replace air which
is being drawn out.
It is essential
therefore that
the
