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 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

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.
