As anyone who has ever had a Bachman 80-ton 3 truck Shay knows, the driveline components crack and split. Also, the bearing blocks are difficult to remove without breaking the small tabs that hold them on. I found a fellow on Ebay selling 3D printed parts for these. Specifically, the bolsters and the bearing blocks. https://www.ebay.ca/itm/30544495487...uid=ulh9LFj1Sh6&widget_ver=artemis&media=COPY If the link doesn't work, just search "Bachmann Three Truck Shay Driveline Repair Parts" and they should come up. They aren't cheap, that's for sure. But I ordered two sets just to see if they were any good. And they fit perfectly. In the photo below the bearing block on the left is a factory one. The one on the right is the 3D printed one from Ebay. This fellow did an amazing job recreating these. I'm not the guy making these, nor am I getting any kind of commission or anything like that. I just wanted to put this info out there as I am sure others are looking for these as well.
