Winchester Winder - firing pin replacement
Mar 27th, 2019 at 12:14pm

I have a low wall Winder, and have a replacement centerfire block.  I need to remove the coil spring and hammer from the current rimfire block.  The hammer pin has a slot on the right side.  Does the pin unscrew, or is it a split pin to drive out?  Also, the coil spring seems pretty tight.  Any tricks/suggestions on how to remove/release it and reinstall, or earlier posts on the topic to refer me to?

Any help is appreciated.

The pin is a split pin with rims on the ends. It gets pushed out.
I don't have and tips on the coil spring.

You don't need to do that. Just take the screw out of the top of the breech block with the action cocked and closed. Then slide the old pin out from the rear and insert the new one. Easy.

I just reread your post and calledflyer is right. If all you are doing is change the FP. (the part I glossed over)
To remove the hammer, extractor and other parts that pin comes out easy.

OK, I should have been more complete.  I am swapping the block, and need to move the hammer and spring from the old block (rim fire) to the new block (centerfire)  I asked the question regarding the firing pin thinking it was a simpler way to present the issue.  My bad - simpler to change the firing pin than I though.

Still need to know how to remove the hammer and spring.

First, take the right sized punch and drive the split pin out by placing your punch on the split end and driving it in the opposite direction. Disconnect the lever. Then take a thin bladed screwdriver and pry each leg of the coil spring out of the breech-block and pull the hammer out.  Swap out your breech-block and then reinstall the legs in the new bridge block. Does your new breech-block have the holes drilled for the coil spring? It helps to dedicate a screwdriver by filing a little notch in the tip of the screwdriver with a three-cornered file.  That helps grab the coil spring and keeps it from slipping off the tip of the screwdriver. Then, it's a matter of pushing the coil's legs upward and against  the resistance until they snap back in the hole.

Thank you, Old-Win from all of us that have cursed the reinstallation of the coil spring. Never thought of the notch to assist. And, curse I did.

Thank you Old-Win.  Just what I was looking for!  Great tip on the screwdriver notch, and I would have tried to drive the split pin from the wrong side - it is opposite from my Martini Cadets where you drive the action pin from the round side, not split side.

The new block (MVA) did not have holes for the coil spring, so I had to drill those.  Not to difficult.

Thanks all.

Remember that your Winder is a cut-down High Wall.

OK, last update.  Success! Finally got around to changing out the hammer.  Thanks to Old Win, it was a two minute job - first removed the pin holding the hammer which relieved spring tension, then used a notched screwdriver to pry the spring from each hole.  Put the hammer in the new block, inserted the pin.  Then the notched screwdriver did its thing, holding the leg of the spring as I pushed it in and moved it to the hole on both sides.  Thanks again.
