Side frames for K-line GG-1

Bill, someone else was looking for these and had a models of them that they wanted me to print for them which I do not do as I haven't enough time for my own projects as it is. I think his name was David

It sounds like a way to go if you can find that person.

Lionel side frames work well for replacements. they just need I tiny bit of filing on the inside of one end of the side frame. both my K line GG1 locos had this problem. seems to be lots of these Lionel side frames on eBay. easy fix. Rick

Thanks, Rick!  It's a nice engine and I want to run it some more.  It's a shame the side frame casings were apparently sub-standard, possibly the alloy used. I'll try the Lionel fix!

Most likely yet another example of Zinc Pest.

I repaired one of those with Lionel side frames. It did take a tiny bit of filing but worked and looked well.

It’s called zinc pest. Read the forum regularly and you’ll learn all sorts of things. This topic has come up every few months, including discussion specifically on the K-Line GG1 sideframes deterioration.

Or do a Google search for more info. Zinc pest is a quality control issue in zinc alloy castings that was a problem in the 1930s and 1940s in American train production and has been again in the past 25 years in Chinese production.
