CT Jack, can you send me the machining information for the o-ring groove you were referring to? I am assuming you have done this in the past. I believe on Bratton’s website (when it was open) they said you needed to install the sleeve bearing 0.09 deep to create the groove which is what I did. I am familiar with the o-ring sizing tables which is why I was surprised at the 0.139 ring that came with the kit. This is why I started the post initially to hopefully see what others did when they installed the kit. Thanks for the help and input.
