A gutted period correct M/C w/stop bolt housing was sent to be rebuilt (sleeved and new guts installed).
Unknown to me, the rebuilder was expecting the MC with the original guts and I guess has the lip seals and o-rings to refurbish.
W/O advising or asking, they decided to gut a new Raybestos MC and substitute the parts gracefully FOC in my Bendix body. On questioning, they really did not know if the parts were an exact match to the Bendix unit (length etc.). By carefully measuring, I found the booster rod bore is 0.010" deeper than the Bendix replacement no stop bolt M/C I was replacing with the period correct one.
I later disassembled the whole damn thing, along with my defective Bendix service replacement M/C to compare the guts. Except as noted above, I found the parts to be generally dimensionally interchangeable.
Part of the the rebuild process when sleeving is they open up the resevoir compensating ports as the sleeve has the smaller metered hole for each resevoir. I assume enlarging the compensating ports in the body allows for some positioning tolerance of the sleeve when being installed.
On real close examination, I discovered they must have broken off the drill bit when enlarging one of the compensating ports in the body and just left it there for me to discover. That port is pretty occluded now, but not totally blocked.
Further inspection revealed they had not bothered to change the flared tubing seats. They assure me they had. Look at the picture and see for yourself.
In conversations with the rebuilder we finally reached a plateau and twisted off, so he has no sympathy or feeling of responsibility for thier crude workmanship or omissions. Leaving me now to find someone who can fix this.
