| Subject: | Re: CKT exhaust springs breaking |
The CKT exhaust on my 912ULS has done 1300 hours without any spring failure so
far. The springs are maintained by a safety wire loop which prevent them from
vibrating, pic attached. However, I had a consistent leak at the spherical joint
on cylinder 3 pipe. I solved that problem using 2 additional springs on that
pipe to increase the pressure on the joint. The those two springs are attached
using safety wire which allows to adjust the tension.
I believe that the use of 4 springs per pipe with properly adjusted tension could
be a solution to also reduce the load per spring, therefore preventing breakage
and increase redundancy.

I don't have a solution for (not) breaking springs other than carrying spares,
but I have found that buying Rotax springs from a Karting shop is rather cheaper.
Same spring, less than half the price....

What marvellous responses in such a short time, from so many of you! This underscores
the great value of continuing to support Matt's website.
Being inherently lazy and not wishing to try out all of your suggestions simultaneously,
I'll start with Remi's suggestion which seems either to dampen resonant
vibrations, or perhaps divide each spring into two lengths with much higher
resonant frequencies.
Many thanks to all of you.

I had the same problem until I ran a bead of the Dow Corning Momentive RTV106 red
silicone sealant. Problem solved - haven't broken one since.

Gary - exactly where did you run the bead of silicon RTV? A picture would be great!
