Hi Hartwig
I tried to respond at the airbus.com address, but it bounced.
Did you get any response on the ZF question?
I'm always interested.

Hello from France,
I have taken the gearbox (dash 2) out of my Pantera for overhaul (oil
leaks and noise). Changing the shaft seals was not a big issue,
however, identifying the root cause of the "singing" noise (at low
power/torque) from the gearbox is more difficult. I checked the pattern
of the crown wheel which seems to indicate that there is a lack of
backlash between pinion gear and crown wheel. In addition, I found that
there is virtually no torque resistance at the differential housing
whereas it should be between 35 and 50 Newton when pulling on a robe
that has been wind around the housing (according to manual). This can
be corrected by changing the shims 907. The issue is that changing
those shims 907 is quite a challenge and I'm scared to break something
because you need to press out the bearing outer ring together with the
roller bearing. Did anybody of you have every tried to adjust the
torque resistance and the backlash of the differential housing?
