Lubrication System Checks; Checking The Oil Level - Detroit Diesel MBE 900 Operator's Manual

OPERATING INSTRUCTIONS FOR STARTING THE ENGINE
be used in the summer. Keep the
coolant level at the bottom of the
filler neck to allow for expansion
of the coolant. For more detailed
recommendations, refer to How
to Select Coolant in the HOW-TO
SECTION of this guide.
3. Entrapped air must be purged
after filling the cooling system.
To do this, allow the engine to
warm up with the pressure cap
removed. With the transmission
in neutral, increase engine speed
above 1,000 rpm and add coolant
to the radiator as required.
4. Check to make sure the front
of the radiator and air-to-air
charge cooler (if equipped) are
unblocked and free of debris.

Lubrication System Checks

The lubricating oil film on the rotating
parts and bearings of a new or newly
overhauled engine, or one which has
been in storage for six months or
more, may be insufficient when the
engine is started for the first time.
NOTICE:
Insufficient lubrication at startup can
cause serious damage to engine
components.
To insure an immediate flow of
oil to all bearing surfaces at initial

engine startup, the engine lubrication
system should be charged with a
commercially available pressure
pre-lubricator. If this is impractical,
rocker covers should be removed and
clean lubricating oil should be poured
over the rocker arms. The oil 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.
For lubricant recommendation,
refer to the How to Select Lubricating
Oil section in this guide.
Checking the Oil Level — Check
the oil level as follows:
1. Remove the dipstick from the
guide tube. Note the dipstick has
a positive locking device such
as a lever or twist-lock design
that must be disengaged before
pulling the dipstick out of the
guide tube.
2. Use a shop rag to wipe off the end
of the dipstick.
3. Wait 15 seconds to allow any
crankcase pressure to dissipate
through the guide tube and let the
oil level settle in the oil pan.
4. Reinstall the dipstick and make
sure it is fully inserted into the
guide tube.
5.
