How to Re-Install an H&R Revolver Main Spring

Hi,
I need the forums help. an elderly neighbor asked me to repair his H&R revolver. With much difficulty I finally identified it as an Old Model, Full Frame, Top Break, Nickel, .32 S&W, 6-shot. It needed a new triger spring which I finally located and replaced. But now I'm embarrassed to admit that I apparently can't install the mainspring correctly. With the mainspring removed the revolver operates normally, i.e., pill the trigger, cylinder revolves, trigger returns. There appears to be only two possible ways to install the mainspring. One places very little tension on the mainspring. When installed in this fashion you can't pull the trigger. The other way involves inserting the mainspring in a notch cutoout on the hammer, requires a great deal of effort to accomplish and the result is the same - the trigger will not pull.

So..............I'm obviously screwing up and just can't figure out where. Does the mainsprig have to be installed with the hammer at the same time? I did not disassemble it that way? Please help - this is project is almost completed for this WW II veteran. So far the parts have cost far more than the value of the revolver but I'm sure you would all agree that this a matter of the heart and he is a worthy recipient.

Thank you,

Dave

Dave,

I have an old H&R break open in .38 if I remember correctly. Mine is missing the trigger spring. I vaguely remember something about the mainspring install, but I got P.O.'d when I couldn't locate the correct trigger spring and haven't touched it in a few years. I'll take a look over the weekend and see what I can see.

Thanks Dillo. This has been a very frustrating experience. I don't consider myself a novice but it took months just to correctly identify this revolver. It has no model designation whatsoever. Numrich has gotten "rich" off me while I ordered the incorrect parts. Calling them was not help either. To get the correct trigger spring I finally resorted to the "shotgun approach" and ordered every H&R trigger spring that could remotely have a chance of fitting the revolver. I got lucky and one did. But the pins listed for it did not and I had to fabricate them. Just looking at the mainspring and the hammer it appears obvious how the mechanism works and how it should be installed. It's that "obvious" thing that gets me every time. Thanks for your help. Dave

Dave,

Bad news/Good News.... I dug out the old H&R Break top. It is a .22, not a .38. The bad news is that, in my frustration of not finding the proper trigger spring, I had left in pieces. The good news is that it jogged my memory.

If I remember correctly (and I may not!), to install the mainspring, you have to remove the pin that retains the trigger assembly. With the trigger floating, the main spring went in with the flat end of the spring placed in the slot in the frame, under the grips. Now the rounded end of the spring is located in the notch of the hammer. The trigger assembly is now squeezed into place from the bottom (I remember a lot of fiddleing to get things right) and the trigger retaining pin is replaced (after locating the trigger spring properly).

This is my best recollection; I rember it being a PITA and never located the right trigger spring, so there she sits. It's on the Someday List.

Hope this helps, but please forgive me if my memory is foggy or incorrect.

Good Luck & let me know how it works out,

Dillo

DAVE STOP



Dave, STOP. I'm Wrong.

Don't remove the trigger assembly!!! I started playing around w/my break top and remembered that I had the trigger out when messing with the trigger spring.

For the main spring I'm pretty sure that you remove the hammer screw ONLY, then get the mainspring in place and push the hammer back into place. This takes some fiddling to get everything in place.

If you remove the trigger assy, you will be looking at the mess that I have now.

Again, take it for what it's worth; It's been a long time!

Hope I caught you in time,

Dillo
