MAINTENANCE
SERVICE PROCEDURE
REPLACE ADDITIONAL FUEL FILTER CARTRIDGE
WARNING
Immediately after the engine is stopped, all parts are at high temperature, so do not replace the filter immediately.
Wait for the engine to cool down before starting the operation.
The inside of fuel piping system of the engine is under high-pressure when the engine is running. When replacing the filter,
wait for at least 30 seconds after the engine stops to let the internal pressure go down before replacing the filter.
Do not bring any fire or spark close.
Be careful when opening the air bleed plug at the fuel filter head and the air bleeder of the supply pump. The system is still
under pressure and fuel may spurt out.
NOTICE
Genuine Komatsu fuel filter cartridges use a special filter that has highly efficient filtering ability. When replacing the filter
cartridge, always use a genuine Komatsu part.
The common rail fuel injection system used on this machine consists of more precise parts than the conventional injection
pump and nozzle.
If any part other than a genuine Komatsu filter cartridge is used, dust or dirt may get in and cause problems with the injection
system. Always avoid using substitute parts.
When carrying out inspection or maintenance of the fuel system, pay more attention than normal to the entry of dirt. If dirt is
stuck to any part, use fuel to wash it off completely.
Container to catch the oil
Prepare a filter wrench
1. Set the container to catch the fuel under the additional fuel filter
cartridge.
2. Using a filter wrench, turn filter cartridge (1) counterclockwise
to remove it.
3. After removing the cartridge, turn cup (2) of the water separator
installed to the bottom of the cartridge counterclockwise. (This
cup is used again.)
4. Install cup (2) to the bottom of the new additional fuel filter
cartridge. (When doing this, always replace the O-ring with a
new part.)
Cup tightening torque: 10 Nm (1.0 kgm , 7.2 lbft)
5. Clean the filter holder, fill the new filter cartridge with clean fuel,
coat the packing surface thinly with oil, then install to the filter
holder.
NOTICE
When adding fuel, do not remove cap (B). Always add fuel from the 8
small holes (A) on the dirty side.
After adding fuel, remove cap (B) and install the fuel filter.
Always fill with clean fuel. Be careful not to let any dirt or dust get into
the fuel. In particular, center portion is the clean side, so do not remove
cap (B) when adding fuel. Be careful not to let dirt or dust get into center
portion on the clean side.
