Thanks for a great lesson. I sure hope it works for me, I hate saying I can't do something.Well, that's just it. When you're replacing springs in the Kadee type coupler ya have to offer one up to the "nowhere" god. He always demands at least one.
The important thing to do though is set your work site up over a desk area with no carpeting under it.
Use an Exacto knife to slice into the spring about three loops from the end. You'll find that the spring will clamp onto the Exacto knife blade and hold there. Put a small dab of CA glue on the end of the spring then guide in onto the little nub on the coupler. Once that's in place, compress the spring so you can slip the open end of the spring over the other nub. Put a tiny touch of CA glue on that end too. The CA glue will keep the spring from ever popping off again. Be careful with the CA glue so ya don't get it into the coupler or else it will end up being a dummy coupler that doesn't open or close.
That is the replacement for Kadee #235 which is the one I use. They discontinued the 235. Wish I could buy a couple more 235s.Take a look at the Kadee #241 uncoupling tool. It's designed to uncouple cars but the best use for me is the opposite end. It works great for spring work. I use mine all the time and rarely lose a spring. They also work great for putting springs in the old sprung trucks.
I did manage to do it after putting the coupler in a vise, but I'm buying a bunch of whisker couplers soon.I have been using Kadee springs I mean couplers since I was 19, oh my 51 years ago. I have never learned the knack of replacing the Springs! I now use the whisker couplers
Well I never said I had a good memory. But yes they have the knuckle spring, maybe i never think of that spring because the whiskers are so darn easy to install!!!Don’t whisker couplers still have knuckle springs?
Why that is terrible. You now have to go back, hope it’s closeDang it, I forgot to pick up a re-railer while I was at the hobby shop.
