Need Newer 629 Re-assembly help

[jschance]

I posted this in the Gunsmithing forum this weekend and didn't get any help, so hopefully someone here might be able to give me an assist.

I've got a 629 that I've gotten apart and cannot figure out how to put it together again.  The problem is in the trigger/hand assembly.  There is a small spring that I believe applies tension to the hand and I can't figure out how it goes in.

Can anyone offer up an assist here?

Thanks.

First, here is a schematic, courtesy egunparts.

If the spring is still captive in the trigger, it's fairly easy.  Use a flat-end jewelers' screwdriver to push the end of the spring so it will be forcing the hand forward when engaged, then jiggle the hand into place.  One of the pins on the hand is the pivot and the other longer one is what the spring will push against.  The long one goes into the curved, elongated hole.

If the spring is not captive you can see its orientation as Part #71 on the schematic.  You can pretty much figure out how the spring should go in by that and by putting the hand in place loosely to see where the spring ends must be to push the hand forward.

Hard to communicate this without the right training aids.

Good luck,
Don

Don,

The spring is not captive, it's running wild and free on my bench

So what is the orientation of the spring, in relationship th the longitudinal axis of the hand?  What do the two ends push against, respectively? (

This is really hard to do without pictures.  Per that diagram the two ends of the spring are tangent to the coil at the bottom of the spring relative to the top of the revolver.  One end pushes against the forward  trigger pin and the other against the hand pin (the long one - last post was wrong).

Here, courtesy of The S&W Revolver - A Shop Manual, by Jerry Kuhnhausen, a book I highly recommend:





Despite that arrow pointing down in the second picture, you'll need to push that end up when you put the hand in place so the spring pushes the long pin down, thus the hand forward.

OK, took a look at it last night.

On the trigger of my 629, there are no trigger pins.

I can't see any way that the spring is retained in the trigger assembly.  Is it held in place by the stud that the trigger pivots on?

This is the first firearm that has stumped me in a long while.  Gotta wonder why Smith chose such a system when a simpler answer could be had.

Ah, you said "newer" 629.  I don't have any experience with those.

Good luck.

Maybe the pictures near the bottom of this page can help...

OK, I got it.

I used the pictures that 'dbriannelson' posted and extrapolated them to the new trigger assembly.  Turns out, that inside the trigger is a space where the spring will lay, and there's a perforation at the bottom of this recess that the short peg of the spring goes into.  The hole for the spring is looks more like a milling mistake than an intentional hole, but I guess it works.

So, with a little patience and a bit of profanity, it's back together, complete with some smoothed internal parts and a new spring kit.

So, there's a happy ending to this little tale.  I still prefer to work in the Ruger actions though.

Thanks for all the help.
