MAINTENANCE
SERVICE PROCEDURE
6. When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it 3/4
of a turn.
If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If the
filter cartridge is too loose, fuel will also leak from the packing, so always tighten the correct amount.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
7. Check that the drain plug at the bottom of the water separator cup is tightened securely.
Tightening torque: 0.2 to 0.45 Nm (0.02 to 0.046 kgm, 0.1 to 0.3 lbft)
8. When carrying out standard replacement of the fuel filter cartridge (every 1000 hours), replace the cartridge and
bleed the air. For details, see "REPLACE FUEL FILTER CARTRIDGE (PAGE 4-62)".
9. Start the engine, check that there is no leakage of fuel from the filter seal surface or water separator mounting
surface, then run for approx. 10 minutes at low idling.
