Uberti Cattleman II conversion cyl. problem

[deadeye dick]

Just got a .45ACP conversion cyl. for my .45 LC Cattleman II. Big problem, it doesn't fit the frame. I am laid up with a broken foot so i haven't had a chance to measure anything up. When i try to slide the new cyl. in place the nub (for lack of another word) on the front of the cyl. where the base pin goes thru, hits the frame. By eye it is longer than the original. Is this standard for a replacement cyl.? Does it have to be tuned to this particular guns frame? I was thinking of stoning it down till it fit but will this interfere with any headspacing issues?
I should be able to hobble to my shop in a few days to measure everything up. Any help would be appreciated.

The bushing (at the front of the cylinder) is removable. Try prying it out (carefully!), cleaning the recess of any debris, and then tapping the bushing back in a little deeper. It seems to me that the bushing wasn't seated as deeply as it should have been. Don't stone it down.

These bushings can be quite tight, and hard to remove. Actually, the first thing to do would be to see if the bushing can be tapped in further, without trying to remove it. Use a plastic-faced hammer.

Thanks. The cyl. is brand new. Should'nt stoning it accomplish the same thing as driving it in. but a little more precise?

Try this. If You want to go back to 45 LC, you do need a new bushing.

The bushing may not be fully seated. If you file/stone the end of it and it later moves back then you will have increased your endshake and the cylider face may start contacting the barrel.
It will not affect static headspace, but will cause variable dynamic headspace. Headspace is set by filing/stoning the back of the ratchet. You will need headspace gauges, feeler gauges, files, and stones to fit the cylinder. Get a copy of Kuhnhausen's Colt Single Action book. It will give you the info you need to do it right.

DD, why not just swap bushings and try installing? You may get lucky and end up with 2 cylinders with 0 endshake. That's the easiest "no work" / "no shim" remedy.

Thanks bill, excellent advice and explanation. The cyl came from Taylors and I waited 4 Mos. I figured it would just slip in. I have a Uberti Stallion .22 with 22 mag cyl. Slipped right in. Could it be the factory left the cyl. proud for tuning? Cant do much now because of a broken foot but will try seating the bushing first and go on from there. Be well Howie
