I found a bit of oil inside the left cap, which had come through the shaft seal. I checked the right mag and found it to be saturated with oil, to the point of almost covering the lowest terminal inside the cap. The left shaft was scored by the seal, but the right shaft was unscored. The best-looking shaft had dumped the most oil. I corrected the condition by installing Speedi-Sleeves on both shafts, and installing new seals. No leakage has been found since. As a result of finding loose rotors recently, I've started to use Hysol (a 2-part structural adhesive...epoxy) to secure the rotors.

I haven't had to lean on him too often for advice, as my engine got to the 200 hour mark pretty quick with no problems. I did, however, try to talk him out of a Jabiru hat when I was at Oshkosh, but no deal...I had to buy a hat just like everyone else...bummer. : ) (I did buy the hat, though) Lynn Matteson Grass Lake, Michigan Kitfox IV Speedster w/Jabiru 2200 flying w/470+ hrs On Feb 6, 2008, at 9:50 PM, Ivan wrote: > > Lynn > The neat thing that I love about the Jabiru so far is the good > documentation and Pete's input.

The first one I did...the left...was about 50 hours ago (and checked 1-2 hours ago), the second one...the right...just 1-2 hours ago. When it comes time to change rotors next time, I'll heat the rotor with a heat gun and it *should* loosen and come right off. I'm betting that the epoxy will hold the rotor so well that changing will become a non- issue. After all, what can go wrong with a rotor under normal (read automotive) circumstances? It just sits there going around and around, with no load or stress on it. Granted, the jumping spark *can* erode the tip, but I've touched auto rotors up with a file, and put them back into service. The button contact area sees no spark jump, and should last forever as well, given a slight buffing with steel wool, for example. To my mind, the 200 hour life span of these parts is based on the "wobble factor"...if it doesn't wobble, why should it fail? I'm certainly not advocating NOT changing rotors and caps, I'd just like to see someone (read: a Jabiru dealer, mechanic, or engineer) point out the real reason for the suggested time frame. When I changed rotors the first time around, due to a distributor oil seal leak, I scoffed at having to glue them on, and I learned my lesson by having them wobble and fail early, so I'm certainly willing to learn from someone who has the real story. In the meantime, weather permitting, I'll continue to log hours on my engine, and do rotor checks at every other oil change and see what happens...hopefully NOT "famous last words" : - ) Lynn Matteson Grass Lake, Michigan Kitfox IV Speedster w/Jabiru 2200 flying w/470+ hrs On Feb 6, 2008, at 10:49 AM, Don Morrisey wrote: > Lynn: > > As someone who is very close to installing my 3300, I am curious > how, after gluing or epoxying the rotors on, they then get removed > the next time around? > > Thanks.
