should be the same weight and viscosity
as that used in the crankcase. After pre-
lubricating, add additional oil to bring the
level to the proper mark on the dipstick.
See Figure 3. Refer to How to Select
Lubricating Oil (page 38) for lubricant
recommendation.
Extended Storage—An engine in stor-
age for an extended period of time (over
winter, for example) may accumulate
water in the oil pan through normal con-
densation of moisture (always present in
the air) on the cold internal surfaces of
the engine. Lube oil diluted by water
cannot provide adequate bearing pro-
tection at engine startup. For this rea-
son, Detroit Diesel recommends
replacing the engine lube oil and filter(s)
after extended storage.
NOTICE:
Failure to eliminate water-diluted lube
oil may lead to serious engine damage
at startup.
Make sure the transmission is filled to
the proper level with the fluid recom-
mended by the gear manufacturer.

Before Starting
Fuel System Checks
Fill the tank with the recommended fuel.
Keeping tanks full reduces water con-
densation and helps keep fuel cool,
which is important to engine perfor-
mance. Full tanks also reduce the
chances for microbe (black slime)
growth. Refer to How to Select Fuel
Oil (page 41) for fuel recommendation.
Make sure the fuel supply shutoff valve
(if used) is open.
To insure prompt starting and even
running, the fuel system must be primed
if air has entered the fuel system.
Priming is done by connecting a manual
or electric priming pump to the sec-
ondary fuel filter. Authorized Detroit
Diesel service outlets are properly
equipped to perform this service.
Priming is not normally necessary if
the filter elements are filled with fuel
when installed and the manifolds are not
drained of fuel.
NOTICE:
Prolonged use of the starting motor
and engine fuel pump to prime the fuel
system can result in damage to the
starter, fuel pump, and injectors, and
cause erratic engine operation due to
the amount of air in the lines and filters
from the supply tank to the cylinder
head.
Engines equipped with starting
devices dependent on compressed air
or gas reservoirs should always be
primed before initial
Otherwise, reserve pressure can be
exhausted and injectors may be dam-
aged from lack of lubrication and cool-
ing.
Under no circumstances should
a starting aid such as ether be
used to run the engine until the
fuel system is primed. Injector
damage will occur if this method
is used. The heat generated by the
external fuel source will cause the
injector tips to be damaged when the
fuel cools them. The plunger and
bushing can be scored from running
without lubrication.
