I have a burr king belt grinder that I bought 20 yrs ago used and its always been smooth, I haven't used it much the last 5 yrs and started back recently grinding a few blade and its developed a bounce in it I pulled the wheels off and ran it and it does it without belt or wheels attached, not as bad but its there, so I pulled the pulleys off and ran just the motor and I still feel it so I think its in the motor, my question is can the motor be fixed like bearings changed out? its a general electric 1 hp 1750rpm, thinking I may take it apart and look, any suggestions?

I think if it's in the motor it has to be a bad bearing and one that is easy to find----there are only two. I would not run it until you make a correction. The motor might ground out. Frank
 
Thanks Frank
I changed out the two bearings and it was so easy it scared me ! I knew it couldn't work! still bouncing a little I think I'll change out the belt next.
