Mine had blown the track right off the board but not blown the actual fuse, did one of my legendary* soldering and good as new!
I didnt take this one down any further, but did on another identical machine, and IIRC the carbon holders lift out of a spade terminal, the armature can then be tapped out and all cleaned up. Pop the black caps off the bearings to re-pack them. All together again and clean out the fan if it's full of shyte!
