Re: Kips sub shaft o-ring
OK - so I finally had some time to engineer nerd out here. The drawing below has all the info and measurements I have. Use at your own risk obviously. But my plan is to modify the groove diameter as per the drawing and give it a go! I also compare used stock measurements to Fredette's oring and to the 008 Xring. My take is use the Fredette's solution, or the Xring, or keep searching for the unicorn packing. Mine will be in the machinists hands tomorrow. If any one is interested, I'm happy to share the SolidWorks files, or as STL / STEP files, and the actual PDF of this drawing. Just PM your email and I'll fire it off............ Cheers - Robert

Kawibunga. that's a neat summary drawing. Thank you! Curious to hear any feedback from the machinist that will cut the groove.

Re: Kips sub shaft o-ring
The young fellow picked it up yesterday. Said it shouldn't be a problem. Their standard narrow cutter is 1/16" and the groove width is .080" so it shouldn't take any special tools. Will post how it all turns out. Just going cost me beer and chicken wings!billie_morini wrote: 06:32 pm May 30 2025 Kawibunga. that's a neat summary drawing. Thank you!

I'm going to bet that my parting tool bit (tall skinny cutoff tool steel bit for lathe use in cutting off a section from the end of a lathe turned work piece) will do nicely. I'll probably finish it off with a piece of emery cloth folded in a U-shape to deburr/polish it.

Re: Kips sub shaft o-ring
Kawibunga, that technical drawing is awesome. thank you for taking the time to make it!
I just wanted to stop by and say my ebay 5x8 red silicone O ring is still holding up. I think it has about 40 hrs on it now and has seen some really high coolant temps and hard running in muddy enduros. I'm tearing the motor down due to a crank seal leak, but the Fredette-inspired economy fix is still holding back air pressure when leak tested @ 5 psi. No visible wear or marring on the O ring.
I've recently acquired a few O rings of the same size made from buna. I will probably try one of these out when i reassemble the engine, but so far the silicone seems totally adequate.
