6. Install cup (2) to the bottom of the new fuel pre-filter car-
tridge.
When doing this, always replace the seal ring with a new
part.
Tightening torque for cup: 10 Nm
When replacing the seal ring, coat the surface with clean
fuel before installing it.
7. Check that drain plug (3) at the bottom of water separator
cup (2) is tightened securely.
Tightening torque: 0.2 - 0.45 Nm
8. Clean the filter holder.
NOTE
When filling the filter cartridge with fuel, carry out the filling oper-
ation with cap (A) fitted.
Cap (A) acts to prevent the entry of dirt or dust into the filter car-
tridge.
9. Fill the filter cartridge with clean fuel through the 8 small
holes (B) in the new filter cartridge.
10. Coat the packing surface of the filter cartridge with oil.
11. Remove filter cartridge cap (A) and install to the filter holder.
12.
When installing, tighten until the packing surface contacts the
seal surface of the filter holder, then tighten it up 1/2 to 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 car-
tridge is too loose, fuel will also leak from the packing, so
always tighten to the correct amount.
When tightening with a filter wrench, be extremely careful
not to dent or damage the filter.
13. When carrying out standard replacement of the fuel filter car-
tridge (every 1000 hours), replace the cartridge and bleed
the air.
Do not put any fuel in the main filter cartridge.
For details see, "Replace fuel main filter cartridge (4-72)".
14. 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
