Good day gentlemen. I need to avail myself once again, of the collected wisdom on this forum.
I've disassembled the gun in the title and as I was getting down to the short strokes, a tiny ball bearing dropped out of the frame. It is not the cylinder alignment ball - it is smaller than that. I measured it and it's .125" - so, even smaller than a B.B. I have a schematic of this gun, which looks to show all its bits and pieces, but this little ball doesn't show up. Do any of you guys have any idea where this belongs ? Thanks for reading. - Doug
 
Looking at the PDF for DW large frame and supermag models, my guess is #19 Cyl Aligning Ball.
I can't trace the line to where it goes, but it's the only one I can find on the parts guide.

Hope this helps.

(E) :cool:
 
Thanks for trying (E), but as I mentioned - it is not the cylinder alignment ball - I'm likely looking at the same diagram that you have. The ball I'm talking about is much smaller.

Good one! Bet you the rear sight was all the way up too.......or partly or fully disassembled.

Well, Brutus - if ya' had money on it, you'd have won. The sight was indeed, all the way up.
So, you guys are saying that this little ball, is part of the rear sight assembly, I take it.

Got a few magnums here. Almost all of us try to max out our shooting distances once we become familiar with our range toys. Hence it lost a bit of it's better ability to cage the bearing.

Especially a nice revolver such as yours with lots of juice behind it.

Cheers buddy!!
 
Hey Brutus - I've had a closer look at the rear sight and I can't see any obvious place, where this bearing would go. Are you able to steer me a bit closer ?
 
^IMO you would have to fully disassemble the rear ramp. At a guess I would surmise it should interact with an adjustment screw or the shaft of it. Perhaps a detent as this has to sit mostly sub surface with something else, like the ramp maybe.

an educated guess here

Okay - thanks for getting back to me. I'll poke around some more and see if I can find a spot for it, in there.

Are we sure it's sporting the factory rear sight and not an OEM sight? Could explain why the bearing is not listed in any DW parts list.

CRANE LOCK INSTALLED INCORRECTLY


Hi folks, I just spent an hour or two trying to work out how to put a shim into the 15/2 revolver to reduce the .010″ gap I had when the cylinder was pushed to the rear, overriding the ball / spring tension.


I was dismayed at the amount of movement forwards and backwards when I push / pulled the crane with the cylinder removed. Couldn't work out how to fix this – I thought the revolver was worn out and that I had wasted my $s.


Fortunately, the crane lock slipped out while I was wriggling the crane, and then IT came to me – I had the machined face of the crane lock pointing to the front of the revolver. If I turned the crane lock around, then the rounded side would face the front of the revolver, pulling the entire crane back towards the rear of the revolver. When I did this, the extra movement or slack in the crane all but disappeared. Felt like a completely different assembly. This also effectively moved the front of the cylinder back a few thousands of an inch.


I then reassembled the 15/2 and am pleased to say, I have a total gap of .005″ when I push the cylinder back as hard as I can towards the rear of the revolver. So the current settings are just under .002″ (firm fit) barrel to cylinder at rest, .005″ total gap when forcing the cylinder to the rear.


JUST BY TURNING THE CRANE LOCK SO THAT THE MACHINED SIDE FACES THE REAR OF THE REVOLVER HAS REMOVED .005″ OF FRONT TO BACK MOVEMENT.


This is also when the revolver is cold and hasn't fired a round.


Tomorrow I'll take it to the range and put a few hundred full loads through it to see what happens.

Unquote

IMO it could be the ball/detent sitting in the crane, the inside machined part that faces the revolver frame indent.
At home I could confirm by looking at my Model 44 with the crane/cylinder in the open position, but I'm two weeks away from that time/place. If this is it, you are also missing a spring and it's firm crimp. Should be an empty hole in there!?!?

PS: I looked at the on-line schematic as well, I think these details are missing from the Numrich parts diagram.

maybe?

I was assuming that it is the stock sight - just because it doesn't look like anything fancy. This sight also has a machine screw (at the rear) to adjust the small notched plate, that moves horizontally, to adjust "windage" - neither of which, show up on the diagram I have. So, who knows ?
Perhaps I should go looking for a more complete/definitive diagram, of this gun.
 
Thanks for that, Brutus. I don't seem to have a ball, or detent, anywhere on the crane (that I can see). As I mentioned in my above post - I'm going to see if I can find a better schematic of this piece.
