Tony,
Your problem could be in either the motor/motion convertor assembly or in the
wheelboxes, but the most likely place is in the wheelboxes. However, since you
have to start by removing the motor assembly either way, I would recommend
you look into the motor assembly first. You can remove the motor assembly by
removing the 5 or six small screws holding the stamped steel cover plate on.
After you remove the cover, you can slip the end of the drive cable out of the
housing, and then remove the motor assembly.
Dissamble the motor assembly and clean it well, removing the decades old
grease from the interior. The motor/motion convertor assembly is a simple
assembly, and it will be obvious what needs to be done as you examine it.
Check the brushes and the internal wiring, and then reassemble. Put the motor
back in place and try it. If it works now, fine; if not take it back out and
go after the drive cable and the wheelboxes.
Often, the screws holding the wheelbox housings together can come loose,
allowing the drive cable to get out of alignment. This can cause the cable to
bind, slowing down, or in bad cases, stopping the motor altogether. Otherwise,
rust, dried grease, or corrosion can cause the wheelbox mechanisms to bind.
Getting the motor out is fairly easy -- not so the wheelboxes, but they are
not impossible to get out, just irritating.
I'm assuming you have checked all the wiring to be sure it's not an electrical
problem!
