4.2 General procedures
4.2.1 Performing a leak-down test
When to perform a leak-down test
After refitting any motor and gearbox, the integrity of all seals enclosing the gearbox
oil must be tested. This is done in a leak-down test.

Performing a leak-down test
NoteAction
Finish the refitting procedure of the motor or gear in
question.
1
Remove the upper oil plug on the gear and replace
it with the leak-down tester.
2
Regulators, which are included in the leak-down test,
may be required.
Correct value:Use caution, apply compressed air and raise the
pressure with the knob until the correct value is
shown on the manometer.
CAUTION
The pressure must under no circumstance be higher
than 0.25 bar (20-25 kPa). Also during the time when
the pressure is raised.
3
0.2-0.25 bar (20-25 kPa)
Disconnect the compressed air supply.4
If the compressed air is signific-
antly colder or warmer than the
gearbox to be tested, a slight
pressure increase or decrease
may occur. This is quite normal.
Wait for approximately 8-10 minutes and make sure
that no pressure loss occurs.
5
If any pressure drop occurred, then localize the leak
as described in step 7.
6
If no pressure drop occurred, then remove the leak-
down tester and refit the oil plug. The test is complete.
Spray any suspected leak areas with the leak detec-
tion spray. Bubbles indicate a leak.
7
When the leak has been localized, take the necessary
measures to correct the leak.
