Description
Articulated Hauler A30C is equipped with an engine type TD103KBE (serial No.–2958, US –60026) and TD104KAE (serial
No. 2959–, US 60027–).
The engine is a straight, six-cylinder, direct-injection, turbocharged diesel engine with intercooler.
The engine type designation, part and serial numbers are stamped into the left side of the cylinder block. The cylinder heads,
one for each cylinder, are mutually interchangeable. The heads have replaceable valve seats and valve guides for both inlet
and exhaust valves.
The valve mechanism receives its movement from the camshaft via push rods and rocker arms.
The injection pump is equipped with a smoke limiter in order to limit the engine torque. The injectors are installed in
replaceable copper sleeves which are pressed into the cylinder head and in direct contact with the circulating coolant.
For repair work on the engine we refer to a separate Service Manual, see the Foreword.

Trouble-shooting
Methods and aids
When a fault is suspected or found, it is important immediately to determine the cause of the fault and identify the faulty
component.
Certain faults are indicated by the red central warning lamp on the instrument panel lighting up at the same time as the
buzzer is sounding or in that the LED (Light Emitting Diode) on the ECU is flashing.
In case of a warning, the engine should be stopped immediately and a service engineer should be called.
In order to facilitate and make the trouble-shooting more efficient, there are a number of aids available.

Contronic Service Display Unit 999 3721
Multimeter 11 666 140
Multi-pin breaker box 11 668 002
With the aid of the Service Display Unit it is possible to determine sensor faults, engine oil pressure and low engine oil
pressure.
In case of a fault/error the Service Display Unit will show an error code (ER indication) and a reading (value) deviating from
the normal. Error codes, possible causes of malfunction and suitable action are described under ”Diagnosis using Service
Display Unit”.
When an error code or a deviating value is shown, measuring resistance is used to establish whether the fault is in a
component e.g. sensor) or if the cable harness to the same is faulty.

Prerequisite condition: The valves are correctly adjusted, see [Invalid linktarget] .
1. Place the machine on level ground and apply the parking brake.
2. Carefully clean around the injectors and at the connections for the fuel delivery pipes and the leak-off fuel pipes.
WARNING
The fuel delivery pipes are pressure prestressed and must under no circumstances be bent or reshaped.
If a pressure prestressed fuel delivery pipe is bent or deformed, there is a great risk that the pipe will break.
A damaged delivery pipe must always be replaced with a new pipe!
Removing
3. Remove the fuel delivery pipes.
CAUTION
Place protective caps on all injectors and on the injection pump connections.
4. Remove the leak-off fuel pipe.
Figure 1
1. 999 6643 Extractor
5. Remove the injector for the number 1 cylinder. When necessary use extractor 999 6643 for taking out the injector.

9. See [Invalid linktarget] . Make sure that the copper washer which is positioned between the injector and the
copper sleeve comes out together with the injector, [Invalid linktarget] . If it does not come out, use a hook made
from a piece of wire to get it out.
Figure 2

6. Install the adapter 999 8009 and secure it using the injector retaining yoke and nut. See [Invalid linktarget] .

7. Connect compression gauge 998 8539. See [Invalid linktarget] .
8. Pull out the stop button and secure the injection pump stop lever in the stop position. This is to prevent fuel from
running out of the delivery valves when the engine is cranked with the starter motor.
9. Check that the gear selector is in neutral.
10. Crank the engine with the starter motor for 5 seconds.
11. Remove the testing equipment and re-install the injector together with a new copper washer.
Tightening torque: 50 N m (5.0 kgf m) (37 lbf ft).
12. Carry out a compression test of cylinders 2, 3, 4, 5 and 6 in the same way as for cylinder number 1.
Remove the pipe between the turbocharger and intercooler when testing cylinder number 6.

10. Normal compression pressure is 2.6 MPa (26 bar) (377 psi) at 220 rpm.
CAUTION
Differences of 10 % in the compression pressure between the cylinders is fully acceptable and does not constitute a
reason for further action as for example valve reconditioning.
Installing
13. Install the leak-off fuel pipe together with new copper washers.
14. Re-install the pipe between the turbocharger and the intercooler.
WARNING
The fuel delivery pipes are pressure prestressed and must under no circumstances be bent or reshaped. If a
pressure prestressed fuel delivery pipe is bent or deformed, there is a great risk that the pipe will break. A
damaged delivery pipe must always be replaced!
15. Install the fuel delivery pipes. Observe the greatest possible cleanliness and make sure that the pipes are not bent
or deformed. Tighten the pipe nuts.
Tightening torque: 15–25 N m (1.5–2.5 kgf m) (18 lbf ft).
16. Restore the stop function. Start the engine and check that there are no leaks.
