Engine Features
All MBE 4000 engines are
water-cooled, four-stroke,
direct-injection inline diesel engines.
Each cylinder has a separate fuel
injection pump (unit pump) with a
short injection line to the injection
nozzle, which is located in the center
of the combustion chamber. The unit
pumps are attached to the crankcase
and are driven from the camshaft.
Each cylinder has two intake valves
and two exhaust valves.
Charge-air cooling and an exhaust gas
turbocharger are standard equipment.
The engine has a fully electronic
control system consisting of a
DDEC-ECU (Engine Control Unit)
and a DDEC-VCU (Vehicle Control
Unit) connected by a proprietary
datalink. This system regulates the
injection quantity and timing using
solenoid valves, allowing extremely
low-emission operation.
Standard engine braking is controlled
by a pneumatically-operated
exhaust brake on the turbocharger
and by a hydraulically-operated
constant-throttle system. For greater
braking power, an optional turbo
brake is available.
The cylinder block has integrated oil
and water channels. The upper section
of the cylinder bore has a carbon
scraper ring seated in a groove on
the top part of the cylinder. The six
All information subject to change without notice. (Rev. 04/08)
individual cylinder heads are made of
cast iron. The cylinder head gasket is
an adjustment-free seal with rubber
sealing elements.
The pistons are made of aluminum
alloy with ring carriers and a shallow
combustion chamber recess. The
pistons are cooled by oil spray nozzles.
The crankshaft is precision-forged
with seven main bearings and eight
custom-forged counter weights, and a
vibration damper at the front end.
The camshaft is made of
induction-hardened steel and has
seven cam bearings. Each cylinder
has cams for intake and exhaust valves
and a unit pump.
The valves are controlled by roller
tappets, pushrods, and rocker arms.
The intake and exhaust valves are
opened and closed by a free-floating
valve bridge.
There is a force-feed lubricating oil
circuit supplied by a gear-type oil
pump. This pump is positioned at the
rear of the oil pan and driven by gears
from the crankshaft. The oil heat
exchanger is integrated with the oil
filter housing on the right-hand side.
The gear-type fuel pump is located
near the front of the crankcase on the
left hand side. The pump is driven
from the forward end of the camshaft.

IDENTIFICATION
The air compressor, with a
power-steering pump attached,
is driven by a gear on the camshaft.
Exhaust
Brake/Constant-Throttle
Valves
The engine is cooled by a closed
system using recirculated coolant;
temperature is regulated automatically
by a thermostat.
To increase braking performance,
the engine is equipped with an
exhaust brake on the turbocharger
in conjunction with constant-throttle
valves on the cylinder head.
See Figure 7.
There are two main drive belts, each
with its own automatic belt tensioner.
The alternator and coolant pump
(and any other accessories) and the
refrigerant compressor are driven by a
main drive belt. The fan is driven by
its own drive belt
NOTE:
On EGR engines, the constant-throttle
valves are activated by engine oil
pressure.
Electrical equipment includes a starter
and an alternator.
The exhaust back pressure is used by
the exhaust brake to increase braking
performance.

EPA04 MBE 4000 ENGINE OPERATOR'S GUIDE
The constant-throttle valves use the
air that escapes through them on the
compression stroke to provide braking
force. The constant throttles are small
valves which are built into the cylinder
heads. When open, a link is created
between the combustion chamber and
the exhaust port.
The engine brake is activated by the
DDEC-VCU. In engine braking mode,
an engine rpm range of up to 2,500
rpm can be used by the operator.
2,500 rpm, however, may never be
exceeded. The engine is turned off
automatically when the engine rpm is:
□ Below 900 rpm for Allison
Automatic Transmissions
□ Below 1100 rpm for all other
transmissions
Also, the engine brake is automatically
turned off when the accelerator pedal
is pressed.
NOTE:
When in emergency running mode
(constant rpm), the engine brake can
be activated only when the engine is
in overrun. When constant rpm has
been attained, the engine brake is
automatically turned off.
Turbo Brake, Optional
engine to provide very high braking
horsepower.
The turbo brake can be operated either
manually or automatically, through
the cruise control function.
Because the charge air pressure is
maintained at a high level during
braking, full throttle response is
available immediately, if the operator
desires it, without any turbo lag.
The turbo brake is maintenance-free,
highly reliable, and adds virtually no
weight to the engine.
Exhaust Gas Recirculation
The purpose of the Exhaust Gas
Recirculation (EGR) System is to
reduce engine exhaust gas emissions
in accordance with EPA regulations.
The MBE 4000 engines for
on-highway EPA 2004 regulation
applications use a cooled EGR system
consisting of an EGR cooler, EGR
control valves, reed valves, and an
EGR mixer.
In the cooled EGR system, part of the
exhaust gasses from the front three
cylinders are routed from the exhaust
manifold through the EGR cooler, past
control and reed valves, and are mixed
with the intake manifold charge air.
For high braking output, the MBE
4000 engine can be equipped with an
optional turbo brake. The turbo brake
increases the air mass flow through the

IDENTIFICATION
The addition of cooled exhaust
gasses back into the combustion
airflow reduces the peak in cylinder
combustion temperature. Less oxides
of nitrogen (NOx) are produced at
lower combustion temperatures.
Electronic Engine Control
System
The engine is equipped with a fully
electronic control system. See Figure

The two control units are connected by
a proprietary datalink through which
all necessary data and information
can be exchanged. The DDEC-VCU
then broadcasts all information on the
J1587 and J1939 datalinks, where it
can be read by minidiag2, the Nexiq™
Diagnostic Data Reader (DDR) or
Detroit Diesel Diagnostic Link®
(DDDL) PC software.
The DDEC-ECU monitors both
the engine and the datalink. When
a malfunction or other problem
is detected, the system selects an
appropriate response; for example,
the emergency running mode may
be activated. For more information

Coolant
containing glycol compounds and
corrosion inhibitors is known as
fully-formulated antifreeze.
NOTICE:
Do not use propylene glycol.
Fully-formulated antifreeze has the
following properties:
□ It protects the radiator and engine
from freezing.
□ It provides protection against
corrosion and cavitation for all
components in the cooling system.
Coolant is a mixture of water and
antifreeze. Under normal conditions,
it is a mixture of 50 percent water
and 50 percent antifreeze, but under
extreme cold weather conditions, as
much as 60 percent antifreeze can be
added. For reasons of anticorrosion
protection and to raise the boiling
point, the coolant must remain in the
cooling system all year round.
□ It raises the boiling point of the
coolant. This slows the rate of
evaporation, avoiding coolant loss
at high temperatures.
Regardless of mileage, replace
the coolant every two years since
the degree of corrosion protection
gradually drops with time.
The water used in the coolant must
comply with certain requirements,
which are not always satisfied by
drinking water. If water quality is
inadequate, the water must undergo
suitable treatment.
Fully-Formulated Antifreeze
Antifreeze approved for use in the
MBE 4000 engine is a mixture of

the requirements of the Truck
Maintenance Council (TMC). Coolant
specifications are listed in Table 2.
□ De-ionized water
NOTICE:
In some areas, tap water can
contain high levels of dissolved
chlorides, sulfates, magnesium, and
calcium, causing scale deposits,
sludge deposits and/or corrosion.
These deposits can damage the
coolant pump and allow the engine
to overheat.
Coolant Specifications
Coolant Concentration
When topping off the cooling system
after a drop in the coolant level, the
concentration of corrosion-inhibiting
antifreeze in the coolant must be
50 percent by volume. This affords
protection down to a temperature of
–37°C (–34°F). The cooling mixing
ratio is listed in Table 3.
NOTE:
If the concentration is too low, there
is risk of corrosion/cavitation in the
cooling system.
To avoid damage to the cooling
system, use only an approved
corrosion-inhibiting antifreeze.
Approved antifreeze must be
fully-formulated and comply with

Supplemental Coolant Additives
for Fully Formulated Coolant
The concentrations of some inhibitors
will gradually deplete during normal
engine operation. SCAs replenish
the protection for cooling system
components. The coolant must
be maintained with the proper
concentration of SCA. Detroit Diesel
Power Cool maintenance SCAs are
recommended.
NOTICE:
Failure to properly maintain coolant
with SCA can result in damage
to the cooling system and its
related components. Conversely,
over-concentration of SCA inhibitor
can result in poor heat transfer,
leading to engine damage.
Always maintain concentrations at
recommended levels. Do not use
traditional SCAs with OAT coolant.
The proper application of SCA will
provide:
□ Water-softening to deter formation
of mineral deposits
□ Cavitation protection to protect
wet sleeve cylinder liners
Dropout
Excessive amounts of some corrosion
inhibitors can cause a gel or crystalline
deposit that reduces both heat transfer
and coolant flow. This deposit is
called "dropout."
Dropout takes the color of the coolant
when wet, but becomes a white or gray
powder when dry. It can pick up solid
particles in the coolant and become
gritty. It will cause premature wear
of the coolant pump seals and other
components of the cooling system.
The wet gel can be removed using an
alkaline (non-acid) cleaner containing
either sodium nitrite or sodium
tetraborate.
If the gel is allowed to dry, it is
necessary to disassemble the engine
and clean it with a caustic solution,
or physically clean the individual
components.
Non-Approved Coolants
□ pH control
The following types of coolant are
not approved for use in MBE 4000
engines:
□ Restored inhibitor levels to prevent
corrosion
□ Antifreeze or coolant containing
phosphate can cause dropout,

overheating, and damage to
coolant pump seals.
□ Automotive coolants offer no
protection against liner pitting,
and generally contain high levels
of phosphate and silicate.
□ Antifreeze based on methyl alcohol
can damage the non-metallic
components of the cooling system.
They are not suitable for use with
diesel engines because of their
low boiling point.
□ Antifreeze based on methoxy
propanol is not compatible with
the fluoroelastomer seals used in
the cooling system.
□ Glycol-based HVAC coolants
contain phosphates which can
deposit on hot internal engine
surfaces and reduce heat transfer.
Recycled Antifreeze
Recycled antifreeze that complies with
TMC RP-329 Type "A" (for ethylene
glycol) is approved for use in MBE
4000 engines. The antifreeze must
be recycled by distillation, reverse
osmosis, or ion exchange.
Other recycled antifreeze, especially
any antifreeze recycled by means of
filtration processes, is not approved.
All information subject to change without notice. (Rev. 04/08)
Corrosion Inhibitors
NOTICE:
Do not mix types of corrosion
inhibitors. Do not add additional
inhibitors to new, fully-formulated
antifreeze, or coolant containing
new, fully-formulated antifreeze.
This can cause deposits or dropout
in the cooling system.
The following types of corrosion
inhibitors are approved for use in
MBE 4000 engines:
□ Supplemental Coolant Additives
(SCAs)
□ Organic Acid Technology (OAT)
Inhibitors
Corrosion inhibitors are very
important in maintaining engine
life. All corrosion inhibitors protect
against corrosion caused by acid,
and cavitation of wet cylinder liners.
SCAs also protect against mineral
deposits.
The concentrations of some inhibitors
will gradually diminish during normal
engine operation. To protect the
engine, nitrite concentration must
be checked at regular intervals, and
inhibitors added as necessary. The
intervals are longer if OAT inhibitors
are used.
DDC-SVC-MAN-0056 04/08 Copyright © 2008 DETROIT DIESEL CORPORATION

SERVICE PRODUCTS
NOTICE:
Always maintain inhibitor at the
recommended level. Failure to
properly maintain coolant with SCA
can result in damage to the cooling
system and related components.
Over-concentration of SCA inhibitor
can result in poor heating transfer
and lead to engine damage.
The following types of inhibitor must
not be used in MBE 4000 engines:
□ Soluble oil additives cause poor
heat transfer and lead to engine
damage.
□ Chromate additives can lead to
the build-up of "green slime"
(chromium dioxide) in the engine,
leading to engine damage.
Disposal
Coolants are biologically degradable
substances.
When disposing of used coolant,
comply with local legal requirements
and waste water regulations.
Consult the local water supply
authorities to determine the best
method of disposal.
A modern engine coolant has complex
tasks to perform. Do not allow any
form of "reprocessing" which consists
only of mechanical purification.

Cold Weather Products
Special precautions must be taken
during cold weather. To protect your
engine, take the following special
measures in cold weather.
□ Use the recommended cold
weather fuel and engine oil.
□ Check the concentration of
antifreeze in your coolant.
□ Take special care of the batteries to
ensure proper cranking amperage
Winter-Grade Diesel Fuel
At low outside temperatures, paraffin
may separate from the diesel and
affect its ability to flow freely. Avoid
breakdowns caused by this problem
(for example, blocked filters) by using
cold-resistant winter-grade diesel
fuel with improved low-temperature
flow characteristics. In most cases,
winter-grade fuel can be used without
problems at cold outside temperatures.
If using summer-grade fuel or a less
cold-resistant winter grade, a flow
improver or kerosene can be added.
The amount needed depends on the
outside temperature.
Flow improver or petroleum spirit
must be mixed with diesel fuel
before its flow characteristics have
been adversely affected by paraffin
separation.

If changes have already been caused

antifreeze protection). Further
increases in the mixing ratio would
reduce the level of antifreeze

FIRE
To avoid increased risk of a fuel
fire, do not mix gasoline and
diesel fuel.
Low-Viscosity Engine Oil
When changing the engine oil,
estimate the interval before your

from the SAE viscosity class
which corresponds to the outside
temperatures anticipated during this
period of operation. See Figure 17.
Winter Coolant Antifreeze

MAINTENANCE
MAINTENANCE
When performed on a regular basis,
changing the engine oil and filters is
the least costly way of obtaining safe
and reliable vehicle operation. Added
benefits and savings occur when you
check that the valves, fuel injectors,
and oil and cooling circuits are in good
working order during oil changes.
The maintenance section of this
manual explains when you should
change your oil and what to look for
when checking for wear or damage.
For additional information, please
contact Detroit Diesel Technical
Service.
Scheduled Intervals
All service intervals and maintenance
operations are based on the parts and
accessories expressly approved for
your engine.
The scope and frequency of
maintenance work are determined
by the engine's operating conditions:
severe duty, short haul, or long haul.
Evidence of regular maintenance is
essential if a warranty claim has to be
submitted.
If optional equipment is installed, be
sure to comply with the maintenance
requirements for these extra items.
60
Important: If the engine is stored for
more than 18 months, the oil must
be changed before the engine can be
brought into service.
Maintenance Schedule Types
There are three types of maintenance
schedule:
□ Schedule I (Severe Service)
□ Schedule II (Short Haul)
□ Schedule III (Long Haul)
To determine which schedule to use,
find the distance traveled by the
vehicle in a year, regardless of vehicle
type.
Severe Service — Applies to
vehicles that annually travel up to
6000 miles (10,000 kilometers) or
that operate under severe conditions.
Examples of Severe Service usage
include: operation on extremely poor
roads or where there is heavy dust
accumulation; constant exposure
to extreme hot, cold, salt-air, or
other extreme climates; frequent
short-distance travel; construction-site
operation; city operation (fire truck,
garbage truck); or farm operation.
All information subject to change without notice. (Rev. 04/08)
DDC-SVC-MAN-0056 04/08 Copyright © 2008 DETROIT DIESEL CORPORATION
EPA04 MBE 4000 ENGINE OPERATOR'S GUIDE
Short-Haul — Applies to vehicles
that annually travel up to 60,000 miles
(100,000 kilometers) and operate
under normal conditions. Examples
of Short-Haul usage are: operation
primarily in cities and densely
populated areas; local transport with
infrequent freeway travel; or high
percentage of stop-and-go travel.
Long-Haul — Long Haul
(over-the-road transport) is for
vehicles that annually travel more than
60,000 miles (100,000 kilometers),
with minimal city or stop-and-go
operation. Examples of Long-Haul
usage are: regional delivery that
is mostly freeway miles; interstate
transport; or any road operation with
high annual mileage.
Maintenance Schedule and
Interval Operations — The three
different schedules of vehicle usage
(severe, short haul, and long haul) are
listed in Table 13. For each schedule,
the appropriate distance interval
(in miles and kilometers) is given
for performing and repeating each
maintenance operation.
The descriptions of all maintenance
operations, indicating all maintenance
operation sets at which each operation
must be performed are listed in Table
14, Table 15, and Table 16.
All information subject to change without notice. (Rev. 04/08)
Maintenance Intervals — The
three maintenance interval tables show
which maintenance operation must
be performed at the actual distances
(in miles or kilometers) for each
maintenance operation. The schedule
of actual distances is based on the
intervals given in the Maintenance
Schedule Table (Table 13).
The three maintenance interval tables
are:
□ Maintenance Interval Table,
Severe Service (Table 14)
□ Maintenance Interval Table, Short
Haul (Table 15)
□ Maintenance Interval Table, Long
Haul ( Table 16)
Maintenance Operation Sets —
Each Maintenance Operations
Sets Table (M1 through M4) lists the
descriptions of only those maintenance
operations that must be performed at
that maintenance operation set. Each
maintenance operation set is listed in
a separate Maintenance Operations
Table.
The descriptions of all maintenance
operations, and the maintenance
operation sets at which each operation
must be performed are listed in Table
17 and Table 18.

MAINTENANCE
Schedule Use
Before placing your new vehicle
in service, determine the correct
maintenance intervals that apply to
your intended use of the vehicle. Refer
to the Maintenance Schedule Table
to determine the distance interval at
which each maintenance operation
must be performed to comply with
your vehicle's schedule.
When the vehicle reaches the actual
distance given for an interval, refer
to the Maintenance Interval Tables
to find the Maintenance Operation
Set that applies to that interval. Then
perform the maintenance operations
listed in the applicable Maintenance
Interval Operation Table.
62
Complete each Maintenance
Operation Set at the required interval.
For example, when you have
completed Maintenance Operation
Set M3 under the 16th maintenance
number listed in the Maintenance
Interval Table, repeat the pattern. For
the 17th maintenance, do Maintenance
Operation Set M1, under the first
maintenance number listed in the
Maintenance Interval Table.
NOTE:
For Severe Service, the pattern
repeats after 15 maintenance
numbers, not 16 (as for Short Haul
and Long Haul).

Required Maintenance
Operations
Gaining Access To The Valves —
Gain access to the valves as follows:
The following sections describe the
required maintenance operations
listed in Table 17 and listed in Table
18.
NOTE:
Clean the cylinder head covers before
removing it.
Engine Inspecting
1. Remove the cylinder head covers.
See Figure 20.
Inspect engine as follows:
1. Visually check the engine for
signs of leakage. A slight
dampness at the sealing points is
no cause for concern.
NOTE:
More severe leaks, combined with a
continual loss of oil, must be corrected
without delay.
2. Visually inspect all lines and
hoses. Listen for any sound of
leaking. Make sure all pipes and
hoses are undamaged, correctly
positioned to avoid chafing, and
properly secured.
Valve Lash Checking and
Adjusting
A special engine cranking tool (J
46167) is required for this procedure.
NOTE:
Adjust the valve lash when the engine
is cold. Wait at least 30 minutes after
shutdown, even if the engine ran only
a short time.

EPA04 MBE 4000 ENGINE OPERATOR'S GUIDE
Method One — Method one allows
you to adjust each cylinder in the
order in which fuel is injected. The
crankshaft must be repositioned
after each cylinder is adjusted as
listed in Table 19.
1. For each cylinder, use the
cranking tool to turn over the
crankshaft until the piston is
exactly at top dead center (TDC)
in the compression stroke. The
valves must be closed and it must
be possible to turn the push rods
without effort.
Engine

NOTE:
When the piston in cylinder #1 is at
ignition TDC, the valves of cylinder #6
will overlap, meaning that both intake
and exhaust valves are partially open,
and show no measurable play when
tested with a feeler gauge.
2. Check each valve and adjust it (if
necessary), using the procedures
under the headings "Checking
Valve Lash" and "Adjusting Valve
Lash."

Method Two — Method two allows
you to adjust all the valves using just
two crankshaft positions.
1. Using the cranking tool, turn the
crankshaft until cylinder #1 is
at the ignition TDC position (all
valves are closed) and cylinder
#6 is at the valve overlap position
(all valves are open).
2. Check the valves listed in Table

Coolant Concentration and
Inhibitor Level Checking
NOTE:
Check and correct the coolant level
only when the coolant temperature is
below 50°C (122°F).
Check the coolant concentration as
follows:
1. Open the cap on the surge tank
slowly, to allow excess pressure
to escape. Set the cap aside.
HOT COOLANT
2. Before adding coolant,
use a suitable tester to
check the concentration of
corrosion-inhibiting antifreeze.
If the concentration is lower
than 50 percent by volume,
drain coolant/add antifreeze until
the concentration is correct.
The coolant mixing ratio is
listed in Table 22.
To avoid scalding from the
expulsion of hot coolant, never
remove the cooling system
pressure cap while the engine is
at operating temperature. Wear
adequate protective clothing
(face shield, rubber gloves,
apron, and boots). Remove the
cap slowly to relieve pressure.

MAINTENANCE
NOTE:
When topping off, use only a
pre-prepared coolant mixture
containing a 50 percent concentration
by volume of corrosion-inhibiting
antifreeze.
NOTICE:
If the concentration of antifreeze is
too low, there is a risk of corrosion
or cavitation in the cooling system.
3. Check the coolant level and add
more coolant if necessary.
Coolant Inhibitor Test
Intervals — Coolant inhibitor
level should be checked at the
intervals listed in Table 23.
Check the nitrite concentration at
regular intervals as listed in Table 24
with a POWER Trac® 3–Way Test
Strip. Nitrite levels must be within
800–2400 PPM. Additional SCA
must be added to the coolant when
it becomes depleted, as indicated by
a nitrite concentration of 800 PPM
or less. If the nitrite concentration
is greater than 800 PPM, do not
add additional SCA. If the nitrite
concentration is above 2400 PPM, the
system is over-inhibited and should
be partially drained and filled with a
50/50 mix of water and EG.
NOTE:
Drain intervals listed in Table 24 are
dependent on proper maintenance.
If topping off is needed, add coolant
which is identical to the initial fill
coolant.

3. Sixty seconds (one minute) after
dipping, compare the nitrite
pad to the color chart on the
container to determine the nitrite
concentration.
4. If the additive indicator (middle
pad) shows any color change,
this indicates the presence of an
unauthorized inhibitor.
5. If there is any doubt about the
quality of the coolant, change the
coolant.
6. After each use, replace and
tighten the cap on the test strip
container. Discard any test strips
that have turned light pink or tan
in color.
7. Close and tighten the cap on the

Rear Engine Power Take-Off
(REPTO)
The REPTO accessory drive is an
option on the MBE 4000 engine. The
drive provides continuous live power
anytime the engine is operating. The
REPTO is driven by the camshaft gear
and is an integral part of a unique
SAE#1 flywheel housing. All REPTO
installations require a torsional
coupling installed at the flange of
the drive unit (i.e. hydraulic pump).
The torsional coupling incorporates a
rubber element designed to reduce the
unwanted stresses from reaching the
engine. See Figure 34.

The torsional damper coupling
will withstand normal exposure to
hydraulic oil, diesel fuel, anti-freeze
solutions, and muriatic acid. The
coupling should be washed with a
mild soap solution and rinsed with
water after contact with the above
