When I ordered a replacement assembly, I was sent a "new" replacement. As I had read up on your site to number the 5 wires BEFORE I removed them, this was a great idea. The new assembly was wired differently than the original board. Although no install instructions came with the new part, it was just a matter of connecting the NUMBERED ... Read more wires to the new configuration. The first time I fired it up after plugging everything in, nothing happened!

Just take pictures of the area BEFORE you disconnect anything and you should do o.k., since I did. 20 minutes.

removed top housing, removed gear housing cover, removed all gears, cleaned out all grease, obtained gears and new housing cover, fit all gears in housing, filled with grease and put on housing cover.
Reassembled mixer.

However, upon closer examination I realized that the same quantity of tabs existed on the new part and although not inline, were clearly marked the same as the original part. Unit was easily replaced and is oper ... Read more ating just like new.

I have replaced so much on this mixer I can take it apart in my sleep. # speed controllers and now 2 gears. just wish we still had the 40 year old mixer we had, never half as many problems. New are not made like the old.
