WATER
TEMPERATURE
A
water
temperature
gauge
when installed
offers immediate
assurance
that the
water
passages
are
free of obstructions and the
water pump is
operating properly
Since the
two
banks of the
engine
have
separate cooling
systems
it is
necessaryto
have
two
gauges
or
warning
devices for each
engine
Normal
water
temperature
readings
will range between
115
to
150
depending
on
the
temperatur
e
of the
water
entering
the
engine
WATER
PUMP
Ear1y
model 283
engines
were
equipped
with
a
rubber
impeller
pumP
A
bronze gear
pump
identified by
grease
cup
on
housing
is
currently
used
Both
type
pumps
are
equipped
with
a
water
seal
which
is automatic
in action
If leak
occurs
around
shaft
this
seal
should
be
replaced
A rubber
impeller
pump
can
often
be
repaired
by replacing
the rubber
impellers
Re
pair
can
be
made
by rexnoving
and
dismantling
pump
The bronze gear
pumP
with
grease
cup requires
little lubrication
Turn
the
cup
one
revolution each
time
oil
is
changed
In
an
emergency
a
worn
pump
can
be
primed
by
turning
the
cup
all
the
way
down
forcing
grease around the
pump
gears
A
worn
pumP
can
often be
repaired
with
new
parts however
if
the
housing
is
worn a
new
pump should
be
obtained
Cooling
water
hoses should
always
be
kept tight
If
seasonal
inspection
shows them
to
be soft
or
deteriorated
they
should
be
replaced
YALVES AND VALVE
TAPPETS
Good valve action
is
very
important
to
the
efficiency
and smoothness of
the
engine
The need for valve
grinding
will irst
be
indicated
by
loss
of
engine speed
increased
fuel
consumption
and
rough
idling
A
check
of the
compression
in
each
cylinder
is
a
reliable check of valve condition
Engines
operated
with proper
care
will
require
a
minimum amount
of valve
vaintenance
In the
new
engine
check valve clearance after
ten to
twenty
hours of
operati
on
Valves
should
be checked every
100 hours of
operation
and
anytime
thehead is removedor the
head bolts
are
adjusted
Clearance
adjustments
should be made while the
errgine
is
hot
Intake
valve clearance should be
4L0
L
a nd
exhausfi
valve clearance
should
be 02011
REVERSE
GEAR
PARAGON MANUAL REVERSE GEAR
OPERATION
The
reverse
gear
is
very
simple
to
operate
With
the
control lever
ahead
forward
drive will be
engaged
and with the lever
in
the middle the gear will be
in
neutral
