went to take it apart the motor bearings were easy to change but the large bearing on spindle shaft was different . The bevel gear is pressed onto the spindle shaft went to press it out and bent the small end of the shaft, also had trouble getting the needle bearing out of the gearcase housing. When all parts arrived it went back together rather quickly and easily.
