Operator`s manual
Breaking-in a
new
engine basically involves seating the piston rings to the cylinder walls.
This
cannot
be
ac-
complished by long periods of running at Idle, nor by early running
at
full
speed.
Idle running may glaze the cylinder
walls,
resulting
in
excessive
oil
consumption
and
smoky operation.
Ex-
cessive speed or heavy overloading, especially with a cold
engine,
may
cause
scoring of the cylinder
walls,
producing similar results.
As
indicated above, operate the engine
in
moderation during the 50-hour break-in period.
(On
one
hand
don't baby the
engine,
but
on
the other
hand,
however, don't abuse
it.)
Starting Under Normal Conditions
Follow the procedure below for normal starting of the engine:
1.
Check the engine
and
transmission lubricant levels
and
fill,
if necessary.
2.
Make sure there
is
sufficient
fuel
on
board.
Keep
fuel
tank(s)
as
full
as
possible. Check the
fuel
filters
and water separators for the presence of contaminants and/or water.
Drain
and
clean them
as
needed.
3.
Check the coolant
level
in
the plastic recovery tank.
Add
coolant solution
as
needed.
NOTE:
Excessive loss of coolant from the plastic recovery tank indicates a cooling system
leak.
Check the entire cooling system
and
pressurize the system to locate the
leak.
In
cases
of excessive coolant
loss, the system must
be
refilled
as
outlined under the
"PREPARATION
FOR
STARTING"
section of this
manual,
page
33.
4.
Check for oil
and
fuel
leaks,
particularly H signs of such leaks are found on the bottom of the engine or
below the engine.
Start the engine
in
accordance with the
"STARTING
PROCEDURE"
instructions found on page
39,
and
allow
the engine's operating temperature to reach
140
- 150' F before operating the engine underway.
Starting Under Cold Conditions
Under extremely
cold temperatures, the following conditions
can
occur. Follow the instructions listed below
when operating your engine
in
cold weather.
LUBRICATING
OIL
TURNS
VISCOUS
-
Make
certain that the lubricating oil
used
conforms with the ratings
for the prevailing atmospheric temperature.
Refer
to the
"LUBRICATION
SYSTEM"
section of this manual,
page
60
for
an
atmospheric/oil viscosity specification table.
VOLTAGE
ACROSS
THE
BATIERY
TERMINALS
DROPS
-
Make
certain that the battery
is
fully charged to
minimize
voltage drop across the battery terminals.
THE
TEMPERATURE
OFTHE
INTAKE
AIR
IS
LOW
AND
THE
COMPRESSION
TEMPERATURE
DOES
NOT
RISE
ENOUGH
-Allow the glow plugs to operate sufficiently to
aid
in
starting during the preheat period when-
ever the temperature of the intake air
is
low
and
when
the compression temperature does not
rise
enough.
Refer
to the preheat chart found
in
the
"STARTING
PROCEDURE"
section, page
39.
