PROCEDURE
1 Do a check of the level switch LS2055A for free flow. If necessary, clean the bore of the
pipe of the level switch.
2 Carefully do a check of the temperature of the oil leakage pipe of each servo oil pipe to
find the leakage pipe that has an oil flow.
NOTE: There is an oil flow in the leakage pipe that has a higher temperature than the
other leakage pipes.
3 Do a check of the related servo oil pipe at the highest inspection point for oil flow.
3.1 Carefully loosen the screw plug (003, Figure 10-1) a maximum of two turns and
look for oil flow.
3.2 If there is an oil flow, repair the cause of the leaks as soon as possible. Refer to
the Maintenance Manual.
3.3 Tighten the screw plug (003).

4 Do Step 3 again for the other inspection points.
NOTE: Step 5 to Step 8 are only applicable for an X82 engine.
5 Do a check of the level switch LS2076A (if applicable also LS2077A) for free flow. If
necessary, clean the bore of the pipe of the level switch.
6 Carefully do a check of the temperature of the oil leakage pipe of each valve control unit
(VCU) to find the leakage pipe that has an oil flow.
NOTE: There is an oil flow in the leakage pipe that has a higher temperature than the
other leakage pipes.
NOTE: As an alternative you can carefully loosen and tighten the screw plug of the
inspection point of each flange a maximum of two turns to find the leakage
pipe that has an oil flow.
7 Cut out the injection of the related cylinder and replace the defective oil pipe, refer to the
Maintenance Manual.
