SERIES 60 SERVICE MANUAL
The oil returns by gravity to the engine oil pan through an external oil line extending from the
bottom of the turbocharger center housing to the cylinder block. See Figure 6-6.
If the turbocharger is water-cooled, the coolant supply line is connected to the bottom of the
turbine housing, and the coolant return/bypass line is connected to the top. Coolant from the fresh
water pump flows through the supply line into the turbine housing, passes into the thermostat
housing then flows back to the heat exchanger, thus lowering its temperature.
For Series 60 engines with Exhaust Gas Recirculation (EGR) systems: The variable nozzle
turbine (VNT) turbocharger uses a high pressure pneumatic actuator to regulate and control the
Exhaust Gas Recirculation (EGR) system. There is no wastegate with this system. The VNT
actuator is mounted on a bracket attached to the turbocharger and receives air pressure from the
engine-mounted Variable Pressure Output Device (VPOD). The VNT actuator connects via a rod
end to a pin joint of the turbine external arm. Rotation of the external arm simultaneously rotates
several pivoting nozzle vanes positioned inside the turbine housing at the outer periphery of the
turbine wheel, adjusting turbocharger speed and boost in accordance with the DDEC engine
management control. A second actuator is the EGR valve actuator that controls the variable
position of the EGR valve. The EGR valve outlet is connected to the EGR cooler and recirculates
a fraction of the engine exhaust gases to the intake manifold for purposes of engine emission
control. The Delta-P (Differential Pressure) sensor uses the differential pressure created by using
a fixed orifice and pressure ports on either side of the fixed orifice to determine the actual EGR
flow rate. The Delta-P sensor is the feedback loop to the ECM so the ECM can increase or
decrease EGR flow via the VPODs, and determine if the EGR system is functioning properly.
The EGR temperature sensor is used in conjunction with the Delta-P sensor to determine flow rate
and the warn operator of EGR system malfunctions.

Removal and Cleaning of Turbocharger
Cleaning the turbocharger is not necessary before removal.
To avoid injury from hot surfaces, allow engine to cool
before removing any component. Wear protective gloves.
To avoid injury from contact with rotating parts when an
engine is operating with the air inlet piping removed, install
an air inlet screen shield over the turbocharger air inlet. The
shield prevents contact with rotating parts.
Many Series 60 engines use turbochargers with ceramic turbine (exhaust) wheels. To avoid
ceramic wheel damage, care must be taken to remove debris after servicing the air intake and
exhaust systems on these engines.

NOTICE:
If the ceramic wheel becomes damaged or bursts, Detroit Diesel
recommends replacing the exhaust system muffler if positioned
in such a way that debris will fall back into the turbine housing.
This precaution will prevent damage to the turbocharger at
engine start-up.
Prior to removal, visually check for:
1. Missing or loose nuts and bolts.
2. Loose or damaged intake and exhaust ducting.
3. Damaged oil supply and drain lines.
4. Cracked or deteriorating turbocharger housings.
5. External oil leakage or coolant leakage, if water-cooled.
6. Replace damaged parts with new parts.
To remove the turbocharger, perform the following:
NOTICE:
Do not attempt to remove carbon or dirt buildup on the
compressor or turbine wheels without removing the turbocharger
from the engine. If chunks of carbon are left on the blades, an
unbalanced condition will exist and subsequent failure of the
bearings will result if the turbocharger is operated. However, it
is not necessary to disassemble the turbocharger to remove dirt
or dust buildup.
1. Disconnect and remove the CAC ducting at the compressor housing.
2. Disconnect and remove the air inlet hose attached to the compressor housing.
Refer to section 6.10.2.
3. Disconnect the exhaust outlet pipe from the turbine housing of the turbocharger. For
proper operation, the turbocharger rotating assembly must turn freely. Whenever the
exhaust ducting is removed, spin the turbine wheel by hand.
4. Remove the inlet oil line from the top of the center housing.
5. Remove the oil drain line from the bottom of the center housing.
6. If turbocharger is water-cooled, drain coolant into a suitable container until engine
coolant level is below the turbine inlet flange. Remove coolant inlet and outlet hoses
from turbocharger.
7. Attach a chain hoist and a suitable lifting sling to the turbocharger assembly.
8. Remove the nuts securing the turbocharger assembly to the exhaust manifold. Then, lift
the turbocharger assembly away from the engine and place it on a bench.

Prior to disassembly, the exterior of the turbocharger must be cleaned. Refer to section 6.6.2,
step 10
Disassemble the turbocharger as follows:
1. Mark the related positions of the compressor housing, center housing and turbine house
with a punch or scribe to assure reassembly in the same relative position.
NOTICE:

Inspection of Turbocharger
Inspect the disassembled turbocharger, discarding any damaged parts, in the following manner:
1. Visually check for nicked, crossed or stripped threads.
2. Visually check the turbine wheel shroud and turbine wheel for signs of rubbing.
3. Visually check the compressor wheel for signs of rubbing or damage from foreign
material. The wheel must be free of dirt and other foreign material.
4. Check the bearing axial end play:

7. Rotate the turnbuckle clamp up and over the S-pipe so that the clamp’s saddle rests in
the bowl on top of the S-pipe.
8. Tighten the nuts on the turnbuckle by hand, making sure that both turnbuckle nuts are
tightened equally. If one side is tightened more than the other, the EGR valve will be pulled
out of alignment, and the exhaust gas path will not be sealed. Leave the nuts finger tight.
9. Finger tighten the nut on the crab at the other end of the S-Pipe.
10. Shift the S-pipe back and forth to ensure that the spherical joints are properly seated and
the parts are aligned. When the manifold, S-pipe, EGR valve and EGR cooler are in
alignment, the crab nut and turnbuckle clamp can be tightened.

EGR Rate Measurement System Installation
EGR Rate Measurement system provides DDEC with measurements resulting in EGR flow
rate prediction. The Rate Measurement system consists of a Venturi with pressure differential
sensor and exhaust gas temperature sensor. Pressure differential between Venturi inlet and throat,
along with exhaust gas temperature are converted to mass flow rate in DDEC. The Venturi is
a component of the delivery pipe.
Install the EGR Rate Measurement System as follows:
1. Install the Delta-P sensor mount over the thermostat housing. Rubber isolators should be
installed on both sides of the mount in each of the three mounting holes. Tighten nuts
over the mounting studs until the nuts come to a hard stop. Torque the nuts to 23-27
N·m (17-20 lb·ft).
2. Install the Delta-P sensor to the bracket with two bolts torque to 30-38 N·m (22-28 lb·ft).
3. Install a hose connector with a clamp on each end to both ports on the sensor bracket.
4. Loosely install two Delta-P tubes to the delivery pipe. The tube ends should line up with
the hose connections on the Delta-P sensor bracket.
5. Loosely clip the Delta-P tubes to the exhaust manifold assembly using clips.
6. Tighten the Delta-P tube nuts to 24-30 N·m (18-22 lb·ft).
7. Tighten the clip bolt to 30-38 N·m (22-28 lb·ft).
8. Tighten the four hose clamps until snug.

TURBOCHARGER SERIES 60 GAS ENGINES (GENSET)
TURBOCHARGER SERIES 60 GAS ENGINES (GENSET)
The turbocharger is designed to increase the overall power and efficiency of the engine. Power to
drive the turbocharger is extracted from the energy in the engine exhaust gas.
A turbocharger can be broken down into 3 basic pieces; a compressor cover, a center housing
rotating assembly (CHRA), and a turbine housing.
The compressor cover is an aluminum alloy casting that encloses the compressor wheel and
provides a V-band connection for the compressor outlet, and a hose connection for the compressor
inlet. The compressor cover is secured to the compressor side of the CHRA.
The CHRA contains a turbine wheel and shaft assembly, piston ring(s), thrust spacer, compressor
wheel, and wheel retaining nut. This rotating assembly is supported on two pressure-lubricated
bearings that are retained in the center housing by snap rings. Internal oil passages are drilled
in the center housing to provide lubrication to the turbine wheel shaft bearings, thrust washer,
thrust collar, and thrust spacer.
The turbine housing is a heat-resistant steel alloy casting that encloses the turbine wheel and
provides a flanged engine exhaust gas inlet and an axially located turbocharger exhaust gas outlet.
The turbine housing is secured to the turbine end of the center housing.
