(lucien) ________________________________ Message 1 _____________________________________ Time: 06:39:12 PM PST US Subject: RotaxEngines-List: slight leak at coolant hose elbow at #1 cyl. From: "lucien" 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?

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) -------- Roger Lee Tucson, Az.

From: "Roger Lee" 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. -------- Roger Lee Tucson, Az.

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?
