I have never Loctited one of those in and I would make it so that you can get it out easily because there's a chance you'll have to remove it to dress the powdercoat in that bore.

That’s my problem I don’t have the trans yet, the bushing is not a press fit so I need to hold it from moving while I rotate my indicator
The BH bore is free from any powder coat.

If the adapter ring just falls in, it's not right. It shouldn't be a press fit either, but should be a slight interference fit.

David, so I checked and it seems tremec still uses the same input shaft bearing retainer on tko and tkx input shafts. The retainer od you are looking for I assume is this one ?

I used a McLeod choke ring ( some call it reducer ring) to allow my Ford OeM bell housing to work with the tko.

I have the tko retainer in my shop and can measure it and report back.

Yes that would be great, there is no OD listed for that retainer anywhere!

Thanks

Ok so for the 429 BB Ford bell housings, my Tremec TKO ( and the TKX) input shaft bearing retainer OD looks to be 4.8500 nominal. I’ve seen the same size quoted for the big block Top loader input shaft trans so it makes sense.
Back during my build when I realized I needed a choke ring I didn’t think I could find one so I drew one up and was ready to have a buddy CNC it, but common sense prevailed, and I called McLeod , they said yup , we have the one you need!

Here is the pic with caliper on it measuring 4.8480. blykins is exactly right, it’s a small interference fit nice and snug. I custom made washers used beneath the 4 mounting bolts to hold the choke ring in place. I could have glued it in with lock-tite but didn’t. My setup has a McLeod bolt on HTOB and thus I removed the Tremec bearing retainer which was handy for answering your question

Awesome!!! thank you very much. It will be the silver ring that Quicktime supplies.
That crazy diameter isn't listed anywhere on the internet, :-(
Now I'm waiting to hear back from the Holley tech gurus for the type of fit the ring should have with my BH opening.
