651-1 conversion to .22LR....Will it require fitting?

[c good]

After reading many threads on this I purchased a Model 63-3 cylinder complete with extractor that is correct for my 651-1. I also purchased an extractor rod, extractor rod spring, rod collar, center pin, and center pin spring.

Should this be almost a "drop in" situation? Or will it require more fine tuning? I have done some light work on my revolvers...changing out hands for timing issues...etc...just wondering if anyone has done this before and what was required to get it right. Thanks, c good

There is a slim chance it will be a "Drop in".

Only once has it happened to me, out of a half dozen cylinder replacements.

The big deal is having one hand work good with ratchets one two cylinders. Hopefully the new cylinder will be the one that needs fitting to the current hand or if not, a new hand will be needed and be fitted to both cylinders.

You will know better than we since you have the cyl already. Why haven't you installed the cyl and tried it yet?

Use your existing extractor Rod and ctr pin (threads are left hand) because they're already fit for length to the gun. First confirm the extractor star from both cyls is the same length (they likely are) before installing the existing extractor Rod and ctr pin and testing the new cyl in the gun. If the same length, you've eliminated one fitting issue and can focus on the cyl fit and hand/timing fit issue of new cyl. Now try the new cyl in the gun. Check the barrel to cyl gap space and compare to the original cyl gap. If close to equal, that's another fitting issue eliminated. (if not, we'll come back to that later.)

If the new extractor star is longer, install the new extractor parts in the new cyl and compare overall length of old cyl and with it's ext rod in place to the new cyl with the new parts installed. If it's longer than old cyl w/rod in place, make the new extractor star the same length as the old star. Compare overall lengths again. If still longer, shorten new ext rod at the front end until they're equal. Confirm ctr pins are equal in length.

Now try new cyl with new parts installed in the gun. If he new cyl functions and times correctly, you're done.

Let us know what you find; to be continued.

I have had more problems with yoke tube length than anything else when doing cylinder replacements. If the tube is a bit short on new cylinder and it has excess end play or drags on the barrel when pressed forward, installing shims to get it right will fix it. If the tube is to long for the new cylinder you need to shorten the tube and keep the end square and then shim the original cylinder for end shake. You could use the cutter from a case trimmer and a pilot that just fits inside the tube, or if your good with a file use that. File, coat end with Prussian blue stick on cylinder press and turn hit any shiny spots lightly. Try the cylinder in the frame regularly. You only want about .001 endshake.

I have had problems with rod and center pin lengths They are an easy fix.

If you don't have patience and are not good with tools a gunsmith is the way to go.

Thank you for the excellent info....I will keep everyone posted. (sent you a pm on the 629 barrel)

I learned a lot reading this thread.

Thanks Hondo and Steelslayer !

I never got a PM on barrel from you. It is steelslaVer not slaYer

Hi Steelslaver,
Resent PM....

My apologies.

If you can believe this, I picked up a 351PD 7-shot 22 Mag cylinder and it times and cycles correctly in one of my rougher 317 22lr targets.
A 6-shot .22 LR cylinder is very likely going to cycle and time in a .22 Mag of the same era.
