The correct torque setting, according to the Rotax Overhaul Manual , is 10Nm (90
inch pounds).
No thread locking compound is used.

Would anyone care to share with us what the correct torque specification is
for this bolt?

I reckon it will be a very good idea to lock it some how. I've never been a
fan of locking compounds, sometime they can work too well and cause other
problems. The correct torque setting is very important, so long as there
are no defects in the threaded hole and it hasn't previously been
over-tourqued.
I'm still amazed to hear that only one bolt holds the cover on. Even if the
thread is fine, there's always the problem of it working loose.
Cheers,
Mark.
