THE WATER
PUMP-TO
DISMANTLE
AND
REASSEMBLE
The
water
pump Is fitted
to
the
front
face of
the
cylinder block, and is driven by a
belt
from
the
crankshaft. This
belt
also drives
the
dynamo.
The
pump
is fitted
with
a specIal carbon gland ring which
provides an efficient
water
seal and needs no lubrica-
tion
or
adjustment.
In
the
early life of
the
car
a slight
leak may occur,
but
this
will automatically cease as
the
carbon
ring beds itself down. Should it be necessary
to
dismantle
the
unit
for
any reason,
remove
the
radiator
and proceed as follows
:-
Remove
the
fan blades by
withdrawing
the
four
set
screws
securing
them
to
the
fan
centre,
and remove
the
fan belt.
