Updated version (11/27/19) - The first 3 pictures in this listing are of our new, updated version of HOn3 improved replacement trucks. What's new? Our improved trucks now include support tabs located on the wheel and worm gear shaft retainers to help keep the sideframes from trying to move around (these can easily be sanded down if need be), the holes located on the truck housings for the sideframe pins now have more support located around them, and the lubricator holes are enlarged. Please see the last picture for a diagram of the new additions made to these trucks.

Thanks to some of our valued customers, we are now offering HOn3 scale improved replacement trucks for MDC Roundhouse 360 Two Truck Shay! 

This listing is for a set (Qty:2) of HOn3 sale improved replacement trucks for a MDC Roundhouse 360 Shay and for the diehard scratch builders. These trucks have been designed with the latest technology in CAD software and 3D printing. Countless hours have gone into the design and testing process to address and fix the many well known issues with the factory original MDC Shay trucks (Such as, bottom cover failing to stay in place, resulting in binding or rough and jerky operation of the locomotive, gear slippage, poor tolerances, excessive wheel play and overall weak construction). The end result in my need for perfection is a very well engineered, strong, reliable and smooth operating truck that you would want and expect to have on any well built locomotive. I also designed these trucks with the convenience and ability to utilize some of the well made original parts from your existing trucks. Such as, original worm gear and shaft, driveshaft coupling, left and right sideframes, geared wheelsets, as well as the original electrical wipers.

Items included in this sale:
2 Truck gear housings, 2 Wheel and worm gear shaft retainers, 2 Gear covers, 8 #1-72 Screws and 2 #2-56 Screws

Items in above pictures that are NOT included in this sale:
Worm gear shaft, Worm gear shaft shims, Driveshaft coupling, Left and right sideframes, Geared wheelsets and Electrical wipers

Please allow for 5-7 days after purchase for us to print and assemble your item. Typically, items will be shipped sooner than this, but please keep in mind that some of our items do take several hours to print out. We do not keep large quantities of our items on hand, due to constant technological and firmware updates. This allows us to send you the best possible product we can offer and a brand new model that has not been sitting on our shelves, collecting dust as you may find with some larger manufacturers.
