ENGINE SERVICE MANUAL 3
Safety Information
This manual provides general and specificservice
procedures essential for reliable engine operation and
your safety. Since many variations in procedures,
tools, and service parts are involved, advice for all
possible safety conditions and hazards cannot be
stated.
Read safety instructions before doing any service and
test procedures for the engine or vehicle. See related
application manuals for more information.
Disregardfor Safety Instructions, Warnings, Cautions,
and Notes in this manual can lead to injury, death or
damage to the engine or vehicle.
SAFETY TERMINOLOGY
Three terms are used to stress your safety and safe
operation of the engine: Warning, Caution, and Note
Warning: A warning describes actions necessaryto
prevent or eliminate conditions, hazards, and unsafe
practices that can cause personal injury or death.
Caution: A caution describes actions necessary
to prevent or eliminate conditions that can cause
damage to the engine or vehicle.
Note: A note describes actions necessaryforcorrect,
efficient engine operation.
SAFETY INSTRUCTIONS
Vehicle
• Make sure the vehicle is in neutral, theparking
brake is set, and the wheels are blocked before
doing any work or diagnostic procedures on the
engine or vehicle.
Work area
• Keep work area clean, dry, and organized.
• Keep tools and parts off the floor.
• Make sure the work area is ventilated and well lit.
• Make sure a first aid kit is available.
Safety equipment
• Use correct lifting devices.
• Use safety blocks and stands.
Protective measures
• Wear protective glasses and safety shoes.
• Wear appropriate hearing protection.
• Wear correct work clothing.
• Do not wear rings, watches, or other jewelry.
• Restrain long hair.
Fire prevention
• Make sure charged fire extinguishers are in the
work area.
NOTE: Check the classification of each fire
extinguisher to ensure that the following fire types
canbeextinguished.
1. Type A — Wood, paper, textiles, and rubbish
2. Type B — Flammable liquids
3. Type C — Electrical equipment
Batteries
Batteries produce highly flammable gas during and
after charging.
• Always disconnect the main negative battery
cable first.
• Always connect the main negative battery cable
last.
• Avoid leaning over batteries.
• Protect your eyes.
• Do not expose batteries to open flames or sparks.
• Do not smoke in workplace.
Compressed air
• Limit shop air pressure for blow gun to 207 kPa
(30 psi).
• Use approved equipment.
• Do not direct air at body or clothing.
• Wear safety glasses or goggles.
• Wear hearing protection.
• Use shielding to protect others in the work area.

4ENGINE SERVICE MANUAL
Tools
• Make sure all tools are in good condition.
• Make sure all standard electrical tools are
grounded.
• Check for frayed power cords before using power
tools.
Fluids under pressure
• Use extreme caution when working on systems
under pressure.
• Follow approved procedures only.

The firing order is 1-2-7-3-4-5-6-8. When viewing the
engine from the rear (flywheel end), the right side
cylinders are numbered 1, 3, 5, and 7. Number one
is the front position. The left side is numbered 2, 4, 6,
and 8.
A two piece crankcase has been specially designed
to withstand the loads of diesel operation. The lower
crankcase has integral main bearing caps. Coolant
and oil passages are cast and machined in the
crankcase and front cover housing.
The crankshaft has five main bearings with fore and
aft thrust controlled at the upper half of the number 4
main bearing. Two connecting rods are attached to
each crankshaft journal. The piston pin moves freely
inside the piston and rod. Piston pin retaining rings
secure the piston pin within the piston.

10 ENGINE SYSTEMS
One piece aluminum alloy pistons are fitted with
one keystone cut compression ring, one rectangular
intermediate compression ring, and a two piece oil
control ring. The combustion bowl (in the piston
crown) reduces exhaust emissions.
The camshaft is supported by five insert bushings
pressed into the crankcase. Two cam lobes, cam
followers, push rods and valve bridges control four
valves per cylinder. The camshaft is gear driven
from the rear end of the crankshaft. A thrust flange
is located between the camshaft gear and the
crankcase. Camshaft thrust is controlled with the rear
surface of the number 5 cam journal and the cam
gear.
Hydraulic cam followers maintain zero valve lash
and minimize engine noise. This eliminates periodic
adjustment of valve lash. The hydraulic cam followers
have rollers which provide excellent cam lobe and
cam follower durability.
The lubrication system uses a crankshaft driven
gerotor pump mounted on the front cover. The oil
pressure regulator is built into the front cover and
is accessible from outside the engine. Lube oil is
routed through an oil cooler equipped with a pressure
controlled bypass valve. Lube oil moves through
passages in the crankcase to lubricate all internal
components and to supply the piston cooling tubes
and high pressure pump reservoir. The VGT and air
compressor use external oil lines.
The VGT is electronically controlled and hydraulically
actuated. The VGT provides boost control at low and
high speeds for improved throttle response.
An exhaust gas recirculation valve allows water
cooled exhaust gases to be fed into the inlet air
stream to reduce exhaust emissions.
A closed crankcase breather system recirculates
crankcase vapors back into the intake air system.
A chassis mounted Charge Air Cooler (CAC), an
air-to-air heat exchanger, increases the density of the
air charge.
Engine operation is controlled by two engine mounted
control modules:
• Electronic Control Module (ECM)
• Injector Drive Module (IDM)
The ECM receives signals from engine and chassis
mounted sensors. The ECM controls engine
operation with the following actuators:
•IPR
• VGT control valve
•EGR
• Glow plug relay
The IDM controls fuel injector operation using data
from the ECM.

The primaryengine systems are AirManagement and
Fuel Management, which share some subsystems or
have a subsystem that contributes to their operation.
• The Electronic Control System controls the Air
Management System and Fuel Management
System.
• The Coolant System provides heat transfer for
EGR gases and lubrication oil.
• The ICP system uses lube oil for hydraulic fluid to
actuate the fuel injectors.
• The Fuel Supply System pressurizes fuel for
transfer to the fuel injectors.
• The Lube Oil System provides lubrication and
