Reply to "Replacement Belt for MTH Dispatching Board"

FWIW, we have been using off the shelf belts to fix these. The belt is T5 pitch, 12.5mm wide 66 0r 67 teeth. We drill a hole in one of the teeth using a micro drill bit of 0.75mm diameter, and then press in the original long pin. In addition, a collar is used on the pin to set the forward distance the belt can move towards the siding gantry. The reason is it's near impossible to get a belt with a ridge in the middle as a guide, but it's not strictly required and with some attention an off the shelf belt can be used.  While this is a 16mm wide example, at worst it hangs off the front edge of the pulleys, but may not then need the collar https://www.amazon.com/Gates-T...Length/dp/B00CJFSLMI

I was hoping I had pictures of the belt in place, but it was done at a friends house. All I could find was measuring the pitch of the original belt and then the video of it working after the replacement belt was installed.
