| Subject: | Mag failure at mag-check |
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.

Lynn:
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.
Blue Skies,
Buz Rich

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.
