3.1.9
Fuel
Specification
The engine must only be used with diesel fuel oil conforming to
the standards for use in modern diesel engines. It is essential
that the fuel should be free from water and contaminants. The
following specifications must be complied with:

Diesel pre-heater
Optionally, a diesel pre-heater can be installed. This is a useful
feature in extremely cold conditions. In this case the fuel filter
will be inside the canopy and there will be a heating element
upstream of the filter preventing the formation of paraffin
crystals in the diesel and clogged filters as a result. The system’s
operation is temperature-dependent and is controlled by a
separate switch to turn it “on” or “off”.
3.1.10
Bio-diesel
The use of diesel fuels to a maximum blend of 5% (by volume)
of Fatty Acid Methyl Esters (FAME) known on the market as B5
diesels is allowed as far as these fuels comply with EN 14214
(Europe) or ASTM D-6751 (USA), as appropriate.
Bio-fuels should be supplied by recognized and authorized
suppliers only. ”Self-blended fuels” may cause engine damage
and will affect warranty.
Please note that free methanol in FAME may result in corrosion
of aluminium parts. Free water in FAME may result in choked
fuel filters and injectors and may result in increased bacterial
growth.
3.1.11
Lubricating oil
1 Specification:
The oil must be suitable for oil changes as specified in the
maintenance chapter. The engine must be run on heavy duty
lubricating oil meeting the requirements of API class CF, CF-4,
CH-4, CI-4 or CI-4 plus . It is recommended to use lubricating oil
from WhisperPower or a well-known brand.
It is very important to use the correct oil
specification. Do not mix different types of oil.
Higher API class oils and synthetic oils are to be
avoided.
2 Oil viscosity:
We recommend 10W40 multi grade oil. In very cold or hot
conditions, a special grade could be applied according to the
Viscosity Chart below:

Oil capacity:
The content of the crankcase and oil filter, is as specified below
(approximate data):
GV/2 Kubota
2.8 L
GV/2 Mitsubishi
3.2 L
GV/3 Kubota
4.1 L
GV/3 Mitsubishi
4.4 L
GV/3+ Kubota
5.1 L
Do not overfill with lubricating oil as this may
have
a
detrimental
effect
on
engine
performance.

Lubricating oil pressure:
Minimum at idle: 49 kPa (0,5 kgf/cm
2
- 7psi).
Normal at 3000 rpm: between 147 and 490 kPa (1,5 up to
5 kgf/cm
2
- 21 up to 71 psi).
Minimum at 3000 rpm: 98 kPa (1,0 kgf/cm
2
- 14 psi).
3.1.12
Cooling liquid
The engine is cooled by cooling liquid. Use only long-life type
G12+ cooling liquid in order to minimize maintenance. The
capacity of the engine’s cooling system is approximately 3.5
litres. The capacities of the radiator and piping have to be taken
into account as well.
Initially, the engine can be filled via the filling cap on the
exhaust manifold. Fill up till the level is just below the filling
cap. Filling of the alternator cooling system and additional filling
of engine cooling system has to be done via the expansion tank.
When the engine is on temperature the liquid will expand and
the redundant liquid will be pressed into the expansion tank.
This tank has to be filled up till the mark. The tank has an
overflow connection, which can be used to connect an open
hose to drain the overflow of the cooling liquid to outside the
vehicle.
