Easily took apart and replaced gears. thanks

Unplugged wires from old switch, plugged them into the new switch. The new Switch have the mounting brackets in different places from the old one. Be sure to match up the numbers by the posts with the correct wires

Remove and replace gear case. Apply food grade grease secure with screws.

1. Removed the decorative band then the upper motor cover.
2. Removed the upper gear case cover. Found one of the two alignment pins broken.
3. Inspected gears.
4. Cleaned out old grease.
5. Repacked with new food grade grease.
6. Reassembled.

3d time in 20 years, but the mixer itself is built like they did 20 yrs ago PartSelect had the part in my mail box in *20 hours* from online order!

BUT - they changed the design so a power switch previously separate from (to the left of) the circuit board is now a microswitch integrated on the board, leaving you with ONE LESS WIRE.
Attached is the fix diagram & directions for the new design.

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.

The repair was easy, I only had to order new gear assembly parts and to replace the associated worn parts (shaft, pin, and gears).

Removed top cover of mixer which was very easy. Then marked the 4 wires so they could be plugged back to new switch correctly. Removed 2 attaching screws to remove switch and one squeeze connector. Installed new switch after plugging on 4 wires. Snapped squeeze connector in place. Reinstalled top cover.

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.

Unscrew the top and remove it , 4 more screws to remove the top of gear box , wipe out the old grease , lift the gears , but to remove the center gear you need a special narrow tip plier to remove the snap ring . Changed the center gear , apply new food grade grease and with reverse order putting back all remaining parts . Worked fine .

Took off all the screws to open the mixer and install the new parts.

REPLACE SPPED CONTROL SWITCH

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 wires to the new configuration. The first time I fired it up after plugging everything in, nothing happened! I removed all the plug-in wires and reinstalled to ensure I had not gotten a tight connection because of the plastic covers over the end connectors. On my second try, everything worked as advertised! VIOLA!!!! It was a bit tough because of the tight spaces within the motor housing and the new wire routing. Just take pictures of the area BEFORE you disconnect anything and you should do o.k., since I did. 20 minutes.

Found a kitchen aid repair video. Found your site for the part I needed. The connections were not like what the video showed but there were enough connector symbols that I was able to understand where they needed to connect. Marking the connections helped for making the new connections when the new circuit board came.

At first thought part was incorrect as the electrical connection tabs on the circuit board were not inline as the existing part. 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 operating just like new.
