New 66-2 Snub, Trouble’shooting’

[Teufelhunden82]

I just picked up a 66-2 snub with matching numbered box, docs and tools off the auction site for $1032. It locks up tight, has no end-shake. Two things I noticed immediately was the rear site is a little wobbly (wiggles slightly fore and aft). I would actually prefer a white-outlined rear site if it has to be replaced, so I’m not too worried there. I also noticed the cylinder would bind slightly just before it reached the fully open position. I figured this was due to dried grease / crud and it just needed a good cleaning and lubrication. When I took it home I cleaned and slightly lubricated the necessary parts but the problem remained. It would open easily and swing out but slowed to a stop before fully swinging out. When I loosened the front screw, it would move freely. When I tightened the screw until it seated, the crane would bind. I tried switching the front and middle screws (not the flat rear screw) and it was the exact same result. I tried the search engine but only found trouble shooting related to unlocking the cylinder. Can anyone shed some light on this? Thanks so much.

the gun might have been disassembled at some point and the two dome head screws swapped by mistake. You might try exchanging these two screws. If this does not work gradually remove a little metal from the tip of the screw holding the crane in place. Trial and error with a stone or fine file. Its a fairly common problem

You mentioned that you swapped the screws so I'd put the better fitting one in the front and as hco mentioned, you'll need to lightly and carefully 'fit' it to your yoke.

It looks to me like you bought a lemon, one that is clearly not worth repairing. Tell you what…I’ll take it off your hands for $10 cash…

Thanks for the tip, I’ll give it a try and report back.

The rear sight blade or slide always has a bit of front to back play. That does not affect the accuracy of the sighting system.

Interesting… I never noticed that before. Thanks for the information, this forum and its members are an incredible resource.

I haven't fitted the front screw to a yoke for a number of years but I looked for signs of contact on the pilot portion of the screw and carefully stoned the side of the pilot. I was also careful to tighten the screw to the same point, since the contact point changes.

Hold on a second!! That yoke is perfectly fit! I was taught to fit the yoke button so that when opening the cylinder the yoke would have some tightness at full opening so that it would remain in position while reloading. Go back to the time when the yoke had a pin inset into the yoke and an indent in the frame so that it held open for reloading. Same thing. With the new spring loaded yoke screws, this concept evaporated.
Who ever fit that yoke/screw knew what he was doing!

Well, I filed the front screw. I made a few strokes, checked for fit, then repeat. It didn’t take much filing to make the cylinder swing fully open without getting hung up. Sounds like there’s more than one way to address this problem, but that’s what I did. Thanks for the input, I’m pleased with how she operates now.
