The roaster is for max of 500 grams http://www.mcmaster.com/#6142k47/=p6a6j4 Valevitola attached the following image: Edited by JackH on 10/31/2013 9:15 AM

Since I live in Guatemala, parts availability is an issue here... :( he said that to change everything would be better but has nothong to replace it with

The one you linked to is plenty powerful and should do a good job. Also, is direction of rotation critical with this roaster? Shaft size of original motor?

Administrator Posts: 3324 Joined: February 23, 2010 Location: Longmont, Colorado	I decided to re-write this to lessen clutter So, what I'm seeing is a universal, AC/DC (brush type) motor driving an open case gear reduction drive. Since the last gear of the drive train is driving the drum mounted gear, it will not be easy to find a gearmotor to replace the open case gear reduction drive you presently have. I'm now in total agreement with Scott that you should find a way to repair your motor. Trying to kluge a high rpm gear motor to the small gear driving your drum will be clumsy and make-shift at best. Is it possible that you're brushes have worn down and is causing the smell? Can you explain more about what the technician meant by "part that converts voltage"?
