5 If none of the connecting pipes have a leakage, find the ICU that has a fuel flow more
than usual (compared to the amount of leakage from the other ICU) as follows:
5.1 Put an oil tray under the screw-in union (008, Figure 10-3 ) of the fuel leakage
pipe (007) to collect the usual fuel flow.
5.2 Carefully loosen the screw-in union (008) a maximum of two turns.
5.3 Do a check of the fuel flow.
5.4 If fuel flows from the screw-in union (008) more than usual (compared to the
amount of leakage from the other ICU), the fuel quantity piston is defective.
Replace the defective fuel quantity piston (refer to the Maintenance Manual
5564
‑
1).
5.5 Tighten the screw-in union (008).
5.6 Do Step 5.1 to Step 5.5 again for the other related cylinders.
