2 truck shay

[willis]

hi all,
i just bought a new 2 truck shay.( well the catalog offer says 2007)
when i opened the package the front truck driveshaft was disconnected.
i took the truck off and reinserted the shaft, no matter how i align the shaft the truck binds when the shaft collapses and it will not pivot all the way compared to fully extended.
it turns sharper to the left than the to the right.
it sticks like it is bottoming out. i hope this makes sense.
the rear truck pivots fine both ways.
thanks, Willis.

Mine does the same.  I'm curious to hear the responses from the group.

You have it figured out. The reason it will turn sharper to the left is the the drive shaft is extended and will allow the truck to pivot more. When turning to the right, the drive shaft is squeezed together and does not allow as much right turn. You could shorten the drive shaft and allow more right turn, but then the drive shaft would fall out when turning left.

If it can take 18" radi in both directions I would not worry, just run it.
