General description The engine is a straight
six-cylinder, turbocharged, four-stroke and
direct-injected diesel engine with an air-cooled
intercooler. It has an overhead camshaft, four
valves per cylinder and unit injectors. The
engine designation is D12DLBE3. The engine is of
low-emission version.

• Figure 1
• The cooling fan with vane motor is located in
  front of the radiator and is driven
  hydrostatically with a variable piston pump,
  Pump 3, (P3).
• The speed of the fan is controlled by the vehicle
  ECU (V-ECU), which receives information about
  temperature in the following systems
• Coolant temperature, radiator
• Coolant temperature, engine
• Transmission oil temperature
• Hydraulic oil temperature
• Temperature in front and rear axle (only when
  machine is equipped with axle oil cooler).
• Induction air temperature
• Charge-air temperature
• Hydrostatically controlled cooling fan speed
  gives the engine high power as well as low sound
  level, since the cooling fan does not work at
  max. rpm as often.

2
The cooling system is based on a concept where
cooling for engine, transmission, hydraulics and
axle oil cooling (optional equipment) are
integrated. These systems' cooling depends on the
cooling fan speed. Engine identification
Identification plate 1 Engine designation, serial
number, part number and assembly plant are
stamped in one field on the engine block's left
rear edge Identification plate 2 A decal with
the software's ID-number, the engine's serial
number and assembly plant is located on the valve
cover to ensure installation of correct ECU on
the engine in production. On the back of the ECU,
there is a decal indicating its hardware
number. Assembly plants A Skövde, Sweden E
Curitiba, Brazil F Flen, Sweden L Lyon,
France Identification plate 3 The certification
decal is located on the valve cover as well as on
the machine frame.

Engine, description The engine type is D10B.
Engine type, product and serial number are
stamped on the cylinder block above the starter
motor (right-hand side of machine).
Figure 1 The engine is a straight six-cylinder,
direct-injected diesel with 9.6 litre cylinder
volume, turbocharger, intercooler and
electronically controlled fuel injection EMS
(Engine Management System). The valve mechanism
is operated by the camshaft via push rods and
rocker arms. The engine is equipped with separate
cylinder heads and wet, replaceable cylinder
liners. The engine has an electronic control unit
(E-ECU), which is located on the engine on the
left-hand side of the engine.
