ihocky2 Posted October 27, 2013 Share Posted October 27, 2013 Recently I've noticed the cylinder on my 625 unscrewing itself while shooting. Thinking I forgot to tighten it properly I never gave it a second thought. I remembered to tighten it down tonight and find that two of the chambers spin freely, two are tight, and two barely move once it is tightened down. I pulled the assembly apart and cleaned everything in detail and put it back together to only find the same problem. It is binding at the same point in the rotation. I am not an expert by any means on revolvers, so I am not sure what is causing this. Even with the cylinder out of the gun and just in the yoke in my hands it is binding. So the problem is somewhere between the yoke and the cylinder when the rod is threaded tight. Link to comment Share on other sites More sharing options...

buckaroo45 Posted October 27, 2013 Share Posted October 27, 2013 My first thought also, bent rod. Link to comment Share on other sites More sharing options...
Toolguy Posted October 27, 2013 Share Posted October 27, 2013 (edited) Sometimes the rod is bent, but most often the problem lies in the threaded connection where the rod screws into the extractor. There has to be a small amount of clearance between the male and female threads or it will seize up when you try to screw it together. The crookedness of the ejector rod usually comes because of the thread clearance. Anytime you take it apart or it comes loose on it's own and you screw it back together it will be crooked again. You can tell if the rod is bent if you take it off and roll it on a flat surface. If it rolls smoothly it is straight. If it's bent it will be obvious. The fix is to tighten it up, then use a fixture with a dial indicator to get it running true again. The problem there is the fixture is expensive and not worth buying to use once or a few times. You need to find someone (a gunsmith) with the fixture and have them true it up for you. Edited October 27, 2013 by Toolguy Link to comment Share on other sites More sharing options...
toothguy Posted October 27, 2013 Share Posted October 27, 2013 Toolguy has a jig made by Power Custom, you need a dial indicator with it as well. http://powercustom.com/store/index.php?main_page=product_info&cPath=2&products_id=103 You rotate the cylinder with the rod attached and the dial indicator shows the high and low bend. I bought a dial indicator with a magnetic base from Enco (about $20) and chucked the rod with the cylinder in my drill press. Slowly turn by hand to find the high spot and carefully put pressure on the side of the cylinder to bend the rod straight. Remember the rod is reverse threaded and you can get an extractor rod wrench from Brownells. Link to comment Share on other sites More sharing options...
revoman Posted October 27, 2013 Share Posted October 27, 2013 You can buy extractor rod's from 8 to 10 dollars and have a few extra on hand for the price you will pay for the tool. Link to comment Share on other sites More sharing options...
toothguy Posted October 27, 2013 Share Posted October 27, 2013 Almost forgot, put some empty shell cases in the chambers to keep the star from turning independently of the cylinder when you loosen or tighten the rod. Link to comment Share on other sites More sharing options...
ihocky2 Posted October 28, 2013 Author Share Posted October 28, 2013 Is there any special fitting that has to be done to install a new extractor rod? For the low price, is it worth changing the center pin while I am at it? Link to comment Share on other sites More sharing options...
Toolguy Posted October 28, 2013 Share Posted October 28, 2013 If they are straight there is no need to replace them. If you want spares, they are cheap. Order all the spare parts you want at one time to save on shipping. Link to comment Share on other sites More sharing options...
Carmoney Posted October 28, 2013 Share Posted October 28, 2013 Check to be sure the female threaded part of the extractor isn't cracked. That can happen if the rod is over-tightened. I have even seen splits in that spot in brand new guns from the factory. The fact that your rod keeps unscrewing makes me suspicious that this might be happening.
