With everything snug and long shaft's end gears properly located to fully engage mating gears, my 213 lift bridge skips gears at the motor drive gear level. Looking down from above as it operates, it appears that the motor can rock slightly side to side, permitting its drive gear to skip gears on the large driven gear. All other gears are mating correctly. Getting to the motor and its mounts to diagnose this requires getting some slack in the wires that travel up one corner from base to motor, and have no slack at the top where needed to lift up the structure top and access the motor. Also, not sure which screws need removing to lift off tower top structure.
Advice on best way to create wire slack, how to remove tower top without damage, and how to address the motor's mounting situation? Is there a shim involved, or is this just a matter of something being loose in the motor's mount situation allowing it to move?
Thanks
