I had to rip the top off of one of my small diameter motors.  I removed 
the screws, then took a pair of longnose pliers to it from there, ripping 
open the side down to the motor shell as if I were using a can opener.  
Crude but effective.

After I burned the reverse relay contacts on my E15 doing rapid 
forward/reverse changes while grading some earth, I repaired things and 
then watched the relay while reversing the motor (in neutral).  There was 
a big, fat arc every time the relay pulled in or dropped out while the 
motor was still turning.  That's defininitely not good for the relay.  

I suppose my varistor could be bad, but it's not that tough to just wait 
until the motor stops before reversing direction.  I never get arcs when 
I do that.
