4.4 Fuel, coolant and lubricants
Use of fuel, coolant and lubricants according to ambient temperature
Maintenance
4-16
WA500-6H – VEAM430100
NOTE
Use only diesel fuel.
The engine mounted on this machine employs electronic control
and a high-pressure fuel injection device to obtain good fuel con-
sumption and good exhaust gas characteristics. For this rea-
son, it requires high precision for the parts and good lubrication.
If kerosene or other fuel with low lubricating ability is used, there
will be a big drop in durability.
Always use the fuel specified for the temperature in the Opera-
tion and Maintenance Manual.
z
If the fuel is used at temperatures lower than the specified
temperature (particularly at temperatures below -15°C
(5°F)), the fuel will solidify.
z
If the fuel is used at temperatures higher than the specified
temperature, the viscosity will drop, and this may result in
problems such as a drop in output.
Note 1:
SAE0W30EOS and SAE5W40EOS must be fully synthetic and
HTHS (High-Temperature High-Shear Viscosity @ 150°C),
specified by ASTM D4741 must be equal to or higher than
3.5mPa-S (3.5cP). KOMATSU EOS0W30 and EOS5W40 are
the most suitable oils.
If these oils are not available, follow the instruction"Recom-
mended brands, recommended quality for products other than
KOMATSU genuine oil (4-18)" at the end of this chapter.
Note 2:
Power train of oil has different properties from engine oil. Be
sure to use the recommended oil.
Note 3:
Axle oil AXO80 has the function of preventing squealing from the
brakes and LSD (Limited Slip Differential).
If only AXO80 is recommended, use KOMATSU genuine AXO80
or equivalent.
Note 4:
When the ambient temperature is higher than 45°C (113°F) and
the machine operation hour is longer than 12 hours/day, then the
use of EO50-CD instead of AXO80 is recommended.
Squealing of the brakes may occur with EO50-CD, but there is
no problem with the brake performance or durability.
Note 5:
Hypergrease (G2- T, G2-TE) is high-performance grease.
In the following cases, we recommend use of G2-T or G2-TE.
1. Every 10 hours greasing for the first 50 hours on a new
machine while it is being broken in
2. When it is needed to improve the lubrication of the grease to
prevent squealing of the pin or bushing
