I inherited my mother's Kitchen Aid she bought around 1977. It was your typical 350a or something liks that everyone owned at the time. 
I used this mixer quite extensively until December of 2012 when my family and I moved. I was using mostly for making some artisan bread from a recipe I found in Mother Earth News. When kneading the dough I noticed it was getting really hot. Almost too hot to touch. It has since been packed away until we have our own kitchen again. Should I send in for service? It isn't making any wierd noises. But it is nearly 40 years old!
