Joe in Mississippi has asked an interesting question that I can't
answer......
How come Rotax places the senders for measuring both CHT and oil
temperatures at the inlet side of the engine??
Seems like what we really need to know is the CHT and the oil temp when it
is at it's hottest, *leaving* the engine....

Roger and all,
Is there a SB on this new regulator? I'm just curious if my engine does or doesn't
have whatever the new parts are in it already (it's a 2005/6 vintage 912ULS).
I'm not really inclined to replace them since I'm not having any problems
with my oil pressure that I can see (only fluctuates a few PSI). But if it _is_
an SB or alert that's strongly suggested or worse, ;), I should probably go
ahead and do it...
Thanks,
LS

Hi Lucien,
Your engine of 2005 does not qualify for the 2000 TOB. The cut off for the engine
serial numbers was right around July 2006 or right in there. you would need
to look at the bulletin if your engine falls right in that time period.
The Rotax SB was SB912-057UL, but had a revision and is now SB912-041UL R2
for the 912ULS

The 912 80 hp is:

I would recommend that all do this little part swap. It is easy and not costly
and does help.

The CHT does nothing, but measure the metal temp on the head. Wouldn't make that
much difference where on the head it was so long as it measured head metal temp.
The oil temp is picked up down by the oil filter area and I can't give you
a good answer to that question. Maybe one of these other guys can.
My guess is that it is a better measure of over all oil temp than hotter oil right
out of the engine, but that's just a guess.

Yeah mine missed it by about a year. And I'd have to replace the crankcase halves
among the other things to make it qualify (may as well get a new engine). But
mine will probably time out before I even get 1500 hours (unless I suddenly
get more time to fly) so I'm not too worried about it.
And like I said my oil pressure doesn't seem to be a problem anyway. Stays in the
low 40's which is well in spec...

Hi Lucien,
With the new oil pressure parts your oil pressure would most likely go up 5 or
more psi. Some have gone up 10-15 psi.
