When I replace the rivets that hold the rollers inside of KW or ZW transformers, I use a brass pin and solder it in place. This prevents the possibility of breaking the roller and makes a much better electrical contact. You might try this approach. Clean everything thoroughly so the solder will tin the metal. You might be able to use the old rivet if you solder the head to the bracket.

I have not replaced any pick up rollers, but I have replaced other riveted parts.
Generally, to remove the rivet, you need to drill or grind the end without the head. The rivet will then push out, freeing whatever was assembled. Unfortunately, the rivet is not reuseable.
There are lots of suppliers for repairs like this. The Train Tender is one that I have dealt with several times. In fact not too long ago I got rivets and springs to rebuild the pick up arms on a Lionel 200 series Alco from them. Check the advertisements in the back of CTT, or do an internet search on 'Lionel parts'.
The trick to these rapairs is finding a way to support the assembly when you peen the rivet to keep it in place. I have a variety of blocks to to support the head of the rivet while I use a 1 ounce ball peen hammer and a center punch to peen the rivet.
Good luck.
I have a few Lionel passenger cars with quite worn rollers which I would like to replace. Each roller is held to its bracket by a rivet. Can someone who has replaced riveted rollers explain the process. Is it possible to salvage the rivet? If not, can I get a new rivet from a hardware store or must it come from Lionel? Any help will be appreciated.
