OPERATION
13
PREPARATION FOR FIRST START
The engine is shipped "dry" ... with lub-
ricating oil drained from the crankcase
and transmission.
Therefore, be sure to
follow these recommended procedures care-
fully before starting the engine for the
first time.
1. Remove oil filler cap and fill oil sump
with heavy duty, diesel lubricating oil
to the highest mark on the dipstick.
See table under Maintenance for an ap-
proved lubricating oil.
Do not over-
fill.
Select an approved grade from
the listing and continue to use it.
2. If the Reverse Gear has a manual clutch,
fill to the highest mark on the dip-
stick with S.A.E. 30 lubricating oil.
You may use the same oil as in the en-
gine.
If Reverse Gear is hydraulic, fill to
the highest mark on the dipstick with
type A Hydraulic fluid.
Do not over-
fill.
3. Fill fresh water cooling system only
after opening all pet-cocks and plugs
until all entrapped air is expelled.
On fresh water cooled engines, fill the
fresh water cooling system with fresh
clean water and/or anti-freeze solution
(see Cold Weather precautions in Main-
tenance Section).
Use a 50-50 anti-freeze solution if cold
weather is to be experienced.
Fill surge tank to within one inch of
the top.
Check this level after engine
has run for a few minutes.
If trapped
air is released, the water level may
have dropped.
If so, refill tank to
within one inch of top and replace
filler cap.
4. Ensure battery water level is at least
3/8" above the battery plates and bat-
tery is fully charged so that it is
capable of the extra effort that may be
required on the first start.
5. Fill fuel tank with clean Diesel fuel
oil; No. 2 diesel fuel oil is recom-
mended.
The use of No. 1 is permissible
but No. 2 is preferred because of its
higher lubricant content.
NOTE:
If there is no filter in the filler
of the fuel tank, the recommended proced-
ure is to pour the fuel through a funnel
of 200 mesh wire screen.
6. Fill grease cup on water pump, if pres-
ent, with a good grade of water pump
grease.
BLEEDING THE SYSTEM
The fuel injection system of a compres-
sion ignition engine depends upon very
high fuel pressure during the injection
stroke to function correctly.
Relatively
tiny movements .of the pumping plungers pro-
duce this pressure and if any air is pres-
ent inside the high pressure line, then
this air acts as a cushion and prevents the
correct pressure, and therefore fuel injec-
tion, from being achieved.
In consequence it is essential that all
air is bled from the system whenever any
part of the system has been opened for
repair or
serv~c~ng.
Running out of fuel
is a misfortune that also necessitates
complete bleeding of the system before the
engine can be restarted.
The following instructions for fuel
system bleeding apply to typical systems
using in-line DPA pumps (shown in Figs.1
and
2).
Before priming and bleeding, insure
that the outside of the bleed screws and
surrounding area is thoroughly clean to
prevent dirt and foreign matter entering
the system.
DPA DISTRIBUTOR PUMPS
The following prim-
ing and venting sequence is applicable to
both mechanically and hydraulically govern-
ed DPA pumps.
The only difference is the
physical location on the pump of the gov-
ernor bleed screw "D" and this is indi-
cated in the appropriate illustration,
