				I had another "mag-out" during a recent mag-check the other day. I  
 said screw it, and flew it home with only one mag firing. (No point  
 in getting into the wisdom of this move...I know it was stupid) The  
 point is, has anybody else had any problems with losing a mag, or are  
 you all changing the rotors and caps at the suggested hourly  
 intervals, and gluing the rotors on?
 
 The second question is, what has been the condition of the rotors  
 that you've removed? Are the rotors all wallowed out where they mount  
 to the distributor shaft?
 
 I checked the rotor in the other mag and found it exactly as I had  
 installed it many (can't recall how many) hours ago. So I now know  
 that my rotor installation procedure is good, and both rotors now  
 have been installed using the same procedure.

 Don't you keep a technical log on your plane??  I keep one on my plane
 similar to the same logs that are kept on certified units, so I can tell how
 long components have been in service.  I also keep the engine log.  Once I
 get the 912 running well I'll probably sell the 582 FWF complete with the
 engine logs which describe all the maintenance on the engine since I've
 owned it.
 
 Sounds like a lot of paper work but really it's not too much and I does tell
 me what I've done and to one extent or the other where to look for problems
 as the arise.

				Lynn,
      I have about 420 hours on my 3300 in the last 25  months and no mag issues at all (in fact no issues of any kind).  I  replaced the caps and rotors at 250 hours not because of problems, but  because the engine manual calls for them to be replaced at 200 hours.   When removed, both caps and rotors were working great and showed no  abnormal wear at the 250 hour point.  I feel they could have gone to 500  hours with no problems, but I believe in preventative maintenance.  I  change oil and filter at 25 to 30 hours and plugs at 100 hours.   As you know, all these replaceable parts on the Jabiru are inexpensive and  readily available at auto parts stores.

				I keep one, but just didn't have it here when I got the urge to write  
 about the recent failure. I'll get the numbers tomorrow, maybe, and  
 post them then.

				Thanks, Buz-
 I changed my first set of caps and rotors at 237 hours, and both  
 rotors were loose. I didn't glue the replacements (Bosch) on, and in  
 time, both became loose. I've finally found replacement parts that  
 I'm happy with...Standard Brand caps, and Daiichi rotors from Car  
 Quest. I've now got the set-up I'm happy with, and time will tell if  
 the epoxy is the secret to holding the rotors on, and allow the  
 rotors to "live out their lives" like they should. I'm not cheap,  
 it's just a pain in the rump to change them with the limited room  
 that I have.
 Personally, I feel that only 200 hours for rotors is way out of  
 line...they should last at least twice that, if not more. I follow  
 the 25-30 hrs for oil changes and filters, though.

				The 2200 and 3300 rotor arms are different parts. The 3300 is more
 upright looking, the 2200 a lot flatter. 
 
 I'm not sure about rotor arm issues with 3300s maybe other 3300 owners
 can let us know? 
 
 I have experienced the same issues as Lynn, lost a mag during pre take
 off check last month on my Jabiru SP but was also close to home so flew
 back on the other one (the airfield I was at was Baltic), I used to fly
 a single ignition Rotax and it was only 15 minutes....
 
 The problem on inspection was indeed the rotor arm and to be frank it
 had been advertising it'self as it did last time one got loose on me.
 Whilst in the cruise every now and again there is a barely peceptible
 hesitation in the smooth running. Problem is it's several hundred hours
 between when I've had it so I don't readily recognise it phenomena (the
 wife said after she had as well). In the past I've picked it us when one
 was loose as it got worse but still worked on the check. This time 150
 hrs from new when it was glued on.
 
 Cause as always the metal spring clip had failed. A bit of corrosion and
 it was in 2 pieces. Genuine Bosch parts. Haven't opened the other one
 yet but will post it's condition when I do. Some anti corrosive spray
 would be good but then that won't help with the glue. Didn't show up
 last time I had the caps off ~50 hrs back. 
 
 Regards, Clive

				Clive-
 Now that you mentioned it, one of my original metal clips was broken,  
 too.
 
 Oh, by the way, I drilled 4 holes around the skirt of the rotor, in  
 line with the interior grooves in the rotor, and when I epoxy the  
 rotors on, the epoxy oozes out of the holes and forms a "rivet" of  
 sorts, helping to hold the rotors on. It may be overkill, but I'd  
 rather be safe than sorry. Incidentally, my original rotors were both  
 sloppy loose when I first inspected them at 237 hrs.
 
 During the recent repair, I looked at the "good" side and it was  
 holding just fine. When I first did the hole drilling thing, I had  
 decided that if that didn't hold, that I would use a Dremel tool and  
 grind a few shallow pockets into the side of the distributor shaft,  
 so that the epoxy could really get a bite onto the shaft. So far that  
 hasn't been necessary.

  Lynn,
      How do you get them off when they need to be  changed nest time?  What am I missing here?

				Lynn,
   
  Are you sure it's a rotor problem  (though rotors loose on the distributor shaft certainly need fixed) and not a  coil problem.
   
  I follow a mainentance program with  numbers close to those below for a total of 312 hours.  Since 285 hours I  have had to replace both coils.  They would work and then not work.   Internmittent in operation.  Heat, or at least a hot day in the fall, broke  down the left coil even though I have cool air blasting on it.  The right  coil left about seven hours ago after it would: first, fail to show an RPM drop  on the mag check, second, completely failing during a mag check.  I should  have suspected it because of rough running and vibration during the previous  four or five takeoffs.
   
  Your coil may check out on the  multi-tester but break down under use.  My engine is an old (serial number  051) 3300.  It had coils with black cases and grey molding at the  end.  New coils have different appearance.
   
  Glad problem is fixed but at $200.80  a pop I felt rather taken advatage of.. heck, it's just some car coil in all  likeiyhood.  
   
  BTW, the original rotors were  tight  when I replaced them and the new rotors stay tight - checked them  when the rough running was encountered. 
   
  cheers jeff

  Don,
   
  I would recommend (take  that for what it's worth) that with the 3300 you need not "glue" them on.   The rotors should be checked before you install by dropping the caps and tugging  on them.  If loose, then exercise a stiff push onto the shaft to see if  perhaps they were not seated in the first place.  
   
  When I replaced rotors at ~  275 hours the old ones were tight and the new ones took  considerable effort to push on shaft.
   
  cheers  jeff

				I replaced my factory installed distributor caps and  rotors last July at 264 hobbs hours. (about 200 tach hours).  The  rotors  had to be forcefully removed as they were very tight to the shaft -  no indications of wear.  
   
  I had one dist cap (L/H I think) that was showing  distress and high wear in the center electrode "carbon button" and the rotor's  corresponding pickup had arcing type wear indications. There  were no indications of any problems during mag checks.
   
  The replaced rotors and caps were procured from Jab  USA.  
   
  The new rotors (Bosch GB73 made in  Australia) were very, very snug fit to  the shafts and I did not use any adhesive.  Current hobbs time on  engine about 350 hrs.
   
  To date, the only work done on the engine has been routine scheduled type maintenance  and minor JSBs which are easily accomplished.  
   
  Love my Jab. Engine is smooth running and easy to start,  although at my lowest start temp to date (Minus 11 C OAT  as per AWOS and my cockpit OAT indicator), the engine did die after about 5  seconds  after start and had to be restarted.

  ---------------------
  has anybody else had any problems with losing a mag, or  are  
 you all changing the rotors and caps at the suggested hourly   
 intervals, and gluing the rotors on?
 
 The second question is, what has  been the condition of the rotors  
 that you've removed? Are the rotors  all wallowed out where they mount  
 to the distributor shaft?
 
 I  checked the rotor in the other mag and found it exactly as I had   
 installed it many (can't recall how many) hours ago. So I now know   
 that my rotor installation procedure is good, and both rotors now   
 have been installed using the same procedure.

				Don and Buz-
 
 Since I began to use the epoxy, I haven't had to remove a rotor. 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"  : - )

 Thanks for the input.  I am unaware of any time frame to replace the Jab 
 3300 engine rotor.  I looked in the service manual for the engine and it 
 says to inspect the distributer and rotor each 50 hours but not to replace. 
 Where did you get info about when to replace the rotor and what was the time 
 frame.  My engine has 120 hrs on it without problems.

				The instructions in the Jabiru manual now specify an inspection on a regular
 basis and if the caps & rotor look good they need not be replaced.  In the
 more distant past there was a statement (maybe in one of the early Jaba Chat
 newsletters) about a service life of 200 hours or two years.

				I'm pretty sure that I read it right here...or on the Yahoo Jabiru  
 list, I'm not sure. I went back and looked through my mail about the  
 time that I had the leaking dist shaft seals, thinking maybe that  
 could have triggered a response from "a person in the know", but  
 couldn't find the reference.

 The neat thing that I love about the Jabiru so far is the good documentation 
 and Pete's input.  I can go to the service manual and know exactly what I 
 have to check, how to do it and how often.  I felt a little unsupported in 
 those areas when I was running my Rotax.

				I have read 200 hrs somewhere on the Jabiru CD - Replaced ours at 300
 because cap was loose, Have done another 600 since with no trouble -
 used Araldite on rotors

				Finding a cap loose at 237 hours was what caused me to remove it and  
 look inside. 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 agree, Ivan....Pete's been good about answering problems. 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)
