#1

I need the universal joint used between the Bachmann 3 truck Shay locomotive and the water tank/tender. Has anybody printed the complete joint, or know of a source for the joint?

Bill,
If i had a sample i could make you a 3d print in an ABS type material on a sla machine.

I have samples of the various parts. Bachmann also has most.

Not sure exactly which of the various parts in this connection is needed

The universal joint I need contains the same parts as those used on a later model 2 truck Shay with one modification. The only difference is the component attached to the cylinder drive shaft. I will remove and disassemble a joint from an existing 3 truck Shay. I will send you the parts if you send me your address.

I would to get 8 of the printed units. I plan build 3 versions of a 4 truck Shay.

I was unable to find any parts for the Large Scale Shay drive train in the Bachmann parts web site. Did I miss something?

Bill, have you been through these pages? First is for 3-truck, then 2-truck. But yeah they’re meager on the drive train parts, at least the 2-truck.

I did search through the Bachman parts store. The universal joint, parts for it, I need aren’t available.

The problem is that we have no idea what part you need.

In a bachmann universal joint there are 4 parts on each half 3 of which are the same. That means the part you need could be any one of the 5 unique parts.

Most of these parts were listed in the Climax section of the bachmann Website but apparently only 2 of the 5 parts are still in stock. I assum ( but without a photo this is likely only an assumption) that your broken part is one of the 3 plastic parts. You can purchase an entire truck that has the required parts but that a tad expensive is you only need one or two parts

Please note that ther are 2 small screws holding the two outside pieces of the universal joint together. Removing these screws ans seperating the joint can also help determine which part neds to be replaced.

I have all these parts I can loan Al but we really neeed to know which part is broken on your shay. If you could share a photo that would clearly help.
