I like Deve's idea and did some measurements. The only problem is that the 12v motor I received is longer than the original 6v motor. If I'm understanding what Deve did correctly, he gutted the old 6 volt motor and put the whole 12 volt motor into the 6 volt case? Deve, did you just use the back of the case from the 6v motor? Did you have to fabricate a sleeve to compensate for the length? Do you have a tech tip or photos of how you did this? Like the idea of retaining the original look using the old gasket!
