| Subject: | spark plug caps for 912UL |
I am in the process of changing the spark plug wires on my older 912 UL
(mid 90's). I am also doing a resistance check on the caps and have found at
least one of them out of the Rotax lower limits (4400 ohms) . All of them
so far have run about 4600 ohms vs the 5000 they should be.
Is there someplace I can buy NGK VDO5FMH plug caps without paying the
almost $50 a piece that Rotax charges ? I can get VDO5EMH caps on line for
about $7 each but I believe they take solid tip plugs vs the threaded that
Rotax calls for.
I have not been able to locate the "F" caps either locally or "on line"
Thanks,
Dick

Dick,
Did some searching and found a french company, LorAvia, which sells them
for 11.00 or about $14.68 each.
http://loravia.com/shop/en/spark-plug-connector-vdo5fmh-nc?keyword=VDO5F
MH&description=true&model=1
If it comes up in French, click on the Brit flag in the upper right and
search on the part number.
I haven't found any US dealers other than the Rotax dealers who want
$50+/- each for them.
Hopefully, someone else can come up with a U.S. source at a reasonable
price.

It is not clear to me from the information given on these caps that they are
specifically for fitting the threaded end of the spark plug after the tip is
removed (as required by Rotax), or if they are for fitting over the cap that
comes on the plug. Can you answer this?

Hugh,
I've attached a part number buildup guide from NGK so that you can see how the
part numbers are assigned. By using the guide you can determine the specification
for each resistor cover.

Hi All,
For the record I've had a nasty vibration creeping into a good flight at 3000 revs
in a 912 uls rotax engine with 1066 revs on the clock. It began to also sound
a little rough at idle, but 3000 was the magic number.
After consultation with fellow listers and doing the carb balancing, prop inspecting
and re-pitching finally sent gearbox away for inspection.
New matched gears installed, and I am glad to report that we are running sweetly
again at all revs!
Thanks to all those who gave meaningful advice once again.. you know who you are..
much appreciated.
All the best for 2013, and safe flying!
cheers
Geoff Bell
