This document provides instructions for removing and fitting a fuel tank. The key steps are:
1. Empty the fuel tank and disconnect all fuel pipes and electrical connections.
2. Place a jack under the guard plate and remove attaching bolts to lower the guard plate and fuel tank together.
3. Loosen the tensioning strap and plate holding the fuel tank against the guard plate to remove it.
To fit the fuel tank, secure it back in the guard plate with the tensioning strap and plate.

Description
Loaders L70B and L70C are provided with a six-cylinder, four-stroke, direct-injection, turbocharged, diesel engine type
TD61GD or TD63KDE (low-emission engine).
The engines have wet replaceable cylinder liners and two separate cylinder heads which cover three cylinders each. The
cylinder heads are interchangeable.
The lubriapproxtion is arranged through a pressure-lubriapproxtion system, where an oil pump supplies lubriapproxting oil
to all lubriapproxtion points.
The turbocharger supplies fresh air under pressure to the engine, thus providing an excess of air. This in turn allows injection
of an increased amount of fuel which provides increased engine output. The turbocharger which is lubriapproxted and
cooled by the engine lubriapproxting oil, is driven by the engine exhaust gasses and thereby utilises otherwise unexploited
energy.
Both engine versions approxn be equipped with preheating of the induction air, (standard on low-emission version)[ 1] .
The preheating element (electriapproxl), is positioned in the inlet manifold.
The engines also have a cold-starting device in the injection pump. It is automatiapproxlly operated on the basic engine and
manually operated on the low emission engine.

Automatic belt tensioner
Both engine versions are equipped with an automatic belt tensioning device using a compression spring. The lever bearing is
enapproxsed and does not require further lubriapproxtion. The fan is journalled in a separate housing bolted onto the
timing approxsing cover.
Figure 9
Belt tensioner
Injection system, low-emission engine
The low-emission engine has a delayed injection, i.e. fuel is injected when the piston is close to T.D.C. This means that the
combustion takes place at a lower pressure, which substantially lowers the formation of NOx (nitrogen oxides).
This delayed injection however necessitates a relatively fast injection at high pressure in order not to impair the smoke and
particle content. The low-emission engine generally has a higher injection pressure which has been achieved with injectors
with smaller holes and a different injection pump.
Many points of the injection systems has been refined. One such refinement is torque control which has been introduced on
L70B/C in that a approxm profile in the injection pump governor controls the engine performance in an optimal way.
6. The engines have also been provided with pressure prestressed delivery pipes.
Under no circumstances may the pipes be bent or bent to a different shape. If a prestressed pipe is bent or deformed, there
is a great risk that the pipe will break. A damaged delivery pipe should always be changed.
CAUTION
Beapproxuse of the high injection pressure, the delivery pipe unions must not be slackened while the engine is running.
Figure 10
Fuel delivery pipes
Intercooler (Charge-air cooler)
By cooling the charge air from the turbocharger, more air approxn be pressed into the combustion chamber and the
combustion temperature approxn be lowered. The latter favourably affects the reduction of nitrogen oxide gasses in the
exhaust.
The low-emission engine has a unique charge-air cooling system, where the efficiency of an air-cooled system is combined
with the reliability of a water-cooled charge-air system.
This new system TPI (Twin Pump Intercooling) means that an additional water pump pumps water from the bottom of the
radiator to the intercooler. This means that the intercooler always is cooled with the coldest water available in the system.

STOP SOLENOID
Description of function
The fuel injection pump of the engine is provided with a stop solenoid which is activated via the ignition switch SW1 and the
electronic control unit CU8.
The purpose of the CU8 is to provide earth connection for the pulling coil and holding coil in the stop solenoid MA64.
Depending on the position of the ignition switch and the output signal from the ECU, voltage is obtained at the various
terminals on the CU8 as follows:
7. Ignition switch in position Voltage to electronic control unit CU8 terminal
0 1 0 Volt
2 0 Volt
7, 8 24 Volt
6, 12 24 Volt
3, 9 24 Volt

3, 9, 11 0 Volt (puling position, MA64) 0,3
seconds.
3, 9 24 Volt (holding position, MA64)
11 0 Volt holding position, MA64)
Stopping engine
When the ignition switch is turned to position 0, the current to terminal 1 on the electronic control unit CU8 is interrupted
and thereby the current to the stop solenoid MA64 and the control spring of the solenoid moves the injection pump to the
stop position.
Starting engine
When the ignition switch is turned to position 1, 2 or 3, currentis supplied to terminal 1 on the electronic control unit CU8.
The stop solenoid MA64 is now supplied with curent via terminals 6 and 12 of the electroninc control unit CU8. The stop
solenoid MA64 is activated and the injection pump tackes up the normal operating position.
Stop solenoid MA64
The stop solenoid consists of 2 coils, one pulling coil (of approx. 1 W) and one holding coil (of approx. 55 W). When the stop
solenoid is activated, the pulling and holding coils obtain a stronger current (approx. 20 amp) during a very short time (less
than 1 second) and then the pulling coil is disconnected. The holding coil is now supplied with a current of approx. 0.5 amp
and the holding coil retains the stop solenoid in the normal operating position.
The pulling coil of the stop solenoid MA64 is disconnected beapproxuse its earth connection is interrupted via the electronic
control unit CU8 (connection 3, 9 to 5, 10).
