4KP26M1XBS4 KitchenAid Mixer - Instructions

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).

Remove covers, open gear box, remove lock ring and gears to deterime which gears were bad. Remove old grease, install new gears and pack with new grease.

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.

First you need to remove the aluminum ring around the housing by using a Phillips screwdriver and removing one screw. You will then have 4 screws around the housing to remove. Once the screws are removed lift the housing and set aside. At the front of the machine there is a housing that encloses the gears. Remove the 4 screws, lift the housing and set aside. At this point you will see the gears and on the shaft there is a snap ring that needs to be removed. Once the snap ring is removed tap the shaft down and remove it from the bottom. To assemble insert the new planetary and reverse the steps to reassemble.

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

Could not get it properly installed. Had to take to a repair center for completion.

using Phillips screw driver, remove 5 screws - take off cowl (cover)l. remove 2 screws holding speed control assembly
unplug old speed control assembly (4 plugs) and plug in new speed control unit - reassemble cowl .

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

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.

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.

REPLACE SPPED CONTROL SWITCH

1. Removed the decorative band then the upper motor cover.

4. Cleaned out old grease.
5. Repacked with new food grade grease.
6. Reassembled.

I went to YouTube and there are several Mixer repair videos that go through step by step. Four ounces of food sate grease is also required as the grease must be changed. This appears to be a a common problem. One issue that I discovered is that the old planetary had an Oring in the shaft The replacement parts do not. They must have changed the design so please make sure that food safe grease is used.

replaced the two Bearing slides thanks to your video repair was quite easy
