| Subject: | Re: Wastegate Adjust |
Hi Jim,
I have been in touch with the Rotax Service Centre in the UK (Skydrive)
and they have advised me as follows: -
"Please see section 78-00-00 page 20 of the Heavy Maintenance Manual for
the correct setting of the servo cable.
The manual is on the CD supplied with the engine or download from
www.rotax-aircraft-engines.com <http://www.rotax-aircraft-engines.com/>
Please ensure the waste gate is fully closed i.e. no slack in the cable
when the throttle is closed (tcu turned on) (it should not be possible
to move the waste gate lever when the throttle is closed).
If the cable is set correctly you can monitor the airbox pressure using
the TLR4* program. Using the monitor sub menu you can see the target
pressure (set point) and achieved (airbox) pressure. Both should be
close to each other other than at low engine speed (below 3500rpm).
You can also see servo position."
I have downloaded this data and it looks fairly simple to do, however
you will need cowls off and an assistant to confirm the wastegate I shut
when you set the cable at the servo drive motor. I haven't done mine yet
as the aircraft is at an airfield some 60 miles from my home where it is
undergoing it's final test flights, I hope to set this up later this
week.
I hope this helps.
Regards

Jack,
Do you have to then purge the oil system?

I don't even remove the plug any more. I just remove the whole can
from the airplane and take the top off, dump out the old oil and clean
everything up as clean as new. Depends on your installation though.
It's actually easier for me to remove the entire sump than to stand on
my head and remove the darn plug. The can needs a good cleaning anyway.

I'm about to do my first oil change on my 912ul. Instructions call
for changing the crush gasket. Is there a generic gasket available at
local auto parts stores?

Pete,
I have not purged exactly as the Rotax video and documentation says you
should, but I am going to start doing it. I didn't really understand the
process until I saw the video they posted at the Rotax web site. Until now
I have made sure the oil line to the thermostat and oil cooler and oil pump
were full, and removed spark plugs and simply turned the engine a bunch by
hand, then with the starter until I get oil pressure on the guage. Next
time I will apply air pressure and check the lifters as recommended. May be
overkill, but it's an expensive engine and deserves the best of care!! And
I would prefer that it not stop running at the wrong moment!
Jack
