just for you information my D32 is #302 and you are right not a big seller. The left wheel does have a slight wobble the right wheel looks good. . The sump pump works however it is loud unless you turn your speed down...the RPM indicator looks ok but I have no idea if it is correct.
Yes the boiler spout leaks a little so I am going to look for one of those mini pails.
I too seek to change belts for the transmission does struggle somewhat.....but happy to have one D32
regards
Howard
