I had to replace my whole buffer not too long ago. I had to take all the guys out and put in a new shell. It cracked up by the handle, right under the warnings on back of buffer. I’m glad it worked out for you. All you can really do, unless there is a service center near you, is take it apart and put pieces in some kind of order and put them back in exactly as you pulled them out, then pray a little, and rev her up. I was overly excited when mine fired up. There was nothing wrong electronically. It was just the shell. The handle was one of the easiest parts.
