Hi:

Working on a train display for the volunteer fire company I'm with, and we have a problem with a recently purchased MTH Sinclair Station. The garage door was not opening, so I disassembled to check the limit switches. They check fine. Messed around a bit with the motor/gearbox that operates the garage door and found the culprit.

 

The shaft on which the "first" gear rides (the gear that meshes with the worm gear) is slightly bent, causing the entire mechanism to bind when opening and closing the garage door. This prevents the accessory from operating through the rest of its cycle unless the door is manually opened.

Has anyone seen this problem previously? Is the gearbox available? If not, does anyone have any suggestions for a repair?

Thanks in advance.
