| Subject: | slight leak at coolant hose elbow at #1 cyl. |
Hi guys,
I have a very slowly developing leak at the upper coolant elbow on my #1 cyl on
my 912uls. I've attached a picture of it (if the attachment goes through that
is). It's a very very slow ooze out of where the elbow comes out of the flange.
It's dry at the seam where the flange contacts the head.
There are no droplets or collections of fluid after a flight (yet), so it doesn't
look like something I'll need to service immediately. But I do want to put
it on the plate.
My question is, I've never serviced one of these - what's the right way to do it?
I didn't see anything in the heavy maint. manual about this. According to the
parts diagram it looks like the elbow screws into the head and there's a rubber
O-ring. Should I just replace the ring or is the elbow user-serviceable?
I.e. unscrew it out and reapply whatever loctite it is they recommend?
Thanks,
LS

I believe CPS will have some of the new Rotax fuel pumps next week. The price will
be the same as the old pump. About $163 for just the pump and $563+ for
hoses and all. Just the pump for me please.
The new pump also has a fitting off it's bottom for a drain hose in case it leaks.
The new Rotax oil filters are out in circulation. They are different and not just
3mm longer. I haven't pulled one apart yet, but you can not
pre-fill the new filters. Don't even both trying. It looks as though there are
two by pass valves. When I get an oil change with one I'll cut one open and take
some pictures. (no I won't cut open a new one)

Take off the fitting. Take a heat gun and warm up the part and unscrew it out of
the base. Clean the threads with some lacquer thinner. Apply some Loctite 648
retaining compound to the threads and re-assemble everything. Let it sit overnight.

Ok, thanks Roger. Sounds pretty straightforward, tho I'll have to get the loctite
from somewhere.
Is this a common problem with the 912 just out of curiosity?
Thanks,
