Feathering shaft/head gasket size

[koi-fish]

What size are the rubber gaskets that fit into both the stock head and the RKH cnc head? Not the brass shims, but the rubber o-rings?

Want to order from a wholesaler instead of hoppy shop. And, want a source after they run out.

Thanks.

They aren't just "rubber o-rings", they are a particular hardness for the job. The wrong hardness will mess up the flight characteristics quite badly.

You get a set (or is it 2?) with a feathering shaft and a set with the grips, so I certainly have accumulated a few. They are also on the grip balls of the mSR X grip-sets so you aren't going to run out. In addition, they last quite a long time.

yep, but I only had one pair and I had two psychotic used MSRs that I was trying to troubleshoot. Turns out they both had bad head gaskets and I had to replace a flybar on one of them.

I used the first pair on one, and found out that I was able to use the red gaskets from the mcpx swash mod on the other (the ones you put on the ball links). Worked quite well. Both are behaving nicely now
