There certainly is old buddy and you picked a good, reliable, easy to main
tain motor. The website to order the video is...
www.homebuilthelp.com
It's called Deep Inside your Rotax 2 Cycle Engine
The one I have is of a 582 and I don't know for sure if they've released
one for the 503 yet or not. I can say that the 582 video was helpful in
a lot of regards to the 503 such as carb. teardown, gearbox removal etc.
etc.

A good article by Conrad Beale from Conair Sports in the UK. It's worth reading
and saving.

| Subject: | Engine Electromagnetic Noise |
RV-12 w/ Rotax 921ULS operating normally. At lower rpm no abnormal noice
in the headset. Upon takeoff lots of noise...crackling, spitting, arcing
type noise. Radio turned off makes no difference, so it seems to be some
radiation getting directly into the Zulu headset, perhaps via the
intercom which is yet to be fully explored.
When reducing throttle the noise disappears...its only at higher rpms.
Have you encountered this? If so, what resolution was found? I can fly
the plane and just put up with the noise which isn't all that terrible,
but want to clear it up. No electrical oddities have been noted.
Thanks for any tips.

| Subject: | Rotax gearbox Inspection Time table |
Hi All,
Here is a reminder about our Rotax 912 gearbox inspection time table. There are
many getting close or already there so make sure you get this done when it is
due. It is a requirement. The only one who can do a gearbox is a "Heavy Maint"
rated mechanic. You do not want your backyard mechanic to mess this up. You
also need a special tool to compress the gear set down and a hydraulic press.
If you have an engine that has the 2000 hr TBO and use 91 oct. unleaded fuel then
you are due at 1000 hrs.
If you have the 2000 hr TBO and use 100LL more than 30% of the time you are due
at 600 hrs.
If you have a 1500 hr. TBO and use 91 oct. unleaded fuel you are due at 800 hrs.
If you have a 1500 hr. TBO and use 100LL more than 30% of the time you are due
at 600 hrs.
I'm sure the rates to do this will differ because of labor cost at each facility.
To clean the clutch of the lead if you have used 100LL then it will be approximately
$100 + shipping from the distributor. You do not necessarily need new
bearings, but if you choose to add that as an option it is about $160 in parts
and another $100 in labor.
All you really need is new Bellville washers ($60) and shimming. If you need only
the inspection then you are looking at roughly 2.5 hrs labor plus the $60 for
the washers. This should be all most of us need. You can have the shop at your
location do it right there or send the gearbox out. Shipping the gearbox is
quite easy. If you have any questions you can call me or Jeremy at CPS. Jeremy
can do these inspections at CPS and I'm also Rotax Heavy Maint rated here in
Tucson.
If you are an owner that blends their fuel with a 50/50 mix of 100LL and 91 oct.
then your due at the earlier times.
If you use 100LL then you will also have to send the slipper clutch in to one of
the distributors (CPS, Lockwood or Leading Edge) to have the clutch dismantled
and cleaned of the lead paste that will render the clutch either inoperable
or greatly inhibited.
There is nothing really good to be said for 100LL and if your aircraft can use
91 oct. unleaded regardless of the ethanol or not, then you are way ahead of the
maint game and it saves you a lot of money, even from day one starting with
low time oil changes.

Well, Roger would charge $50 hr. from start to finish. So about 2.5 hrs, plus the
washer parts @ $60. If you fly in I have to pull the prop and box so it is
a tad more verses sending it to me. Works for me either way.
