Lionel 238e...drive rod screw problem

Specialized tools are needed to remove and replace Lionel wheels properly.  And if you're just learning repairs, this wouldn't be the first repair I'd attempt, IMHO.  Of course, the most authentic fix is to replace the wheel.

If this were my engine, I think I'd put a dab of J.B Weld at the bottom of the screw hole, and on the tip of the screw, then insert the screw to the proper depth.  Maybe a tiny drop of oil on the inside of the drive rod and at the head end of the screw, so they don't accidentally get stuck.  I'll bet that J.B. Weld holds it.  If you're unfamiliar with the product, it's a special 2-part epoxy for use on metals and is available at the big box home improvement stores, hardware stores and auto parts stores.  Good luck!

I concur with the J.B. Weld solution.

 It sounds like the epoxy may keep the screw from coming out permanently. If you need a solution that will allow you to be able to remove the screw, try wrapping a few turns of teflon plumbing seal tape around the threads. Alternatively, a few drops of a threadlocker product may hold the screw in place, and allow you to remove it again in the future. Coating the threads with paint, or even nail polish may keep the screw in place if the threads in the wheel are not too worn.

I have successfully repaired stripped wheel threads with Helicoil Inserts. Using this method, the screw works normally.  The repair is not visable and the repaired threads are stronger than the originals.

Thanks to all of you guys,,,

these are good suggestions

I once used a thread repair epoxy that worked well. I found it in the auto parts section. You mix it up and then after coating a screw with a release coating, screw in the screw and let it cure. Back out the screw and attach whatever. I was pretty impressed with it.
