KSM151 KitchenAid Mixer - Instructions

First i went to the Kitchen Aid web site and found a video on how to take a part the mixer. Followed the instructions from the video and it was very easy. The grease in the machine was black so i cleaned it out of the transmission and repack it with hi-heat wheel bearing grease that i got from a auto parts store it took about a 1/2 lb. ... Read more then put the gasket in and back together and put the o-ring on. Have run for awhile and it is ok. Want to say that these are very well built machine.

Found control backplate out of adjustment. Should be nominal 3/8".Broken speed control spring which attaches to backplate bottom.
I recommend Loctite Blue to complement locknut's when adjusting RPM of "Stir" speed

Repair went well after I figured out how to dis-assemble the mixer. Used straight & phillips screwdrivers and a small hammer & punch to drive out 3 pins. Ordered part# PS734233 pinion & shaft as shown in the parts page, it arrived on schedule, received part # 240210-2. Only problem was the new pinion had 10 teeth, the old/failed pinion ha ... Read more d 11 teeth. Could not learn from anyone I called at PartsSelect or Whirlpool if the 10 tooth pinion was the correct part to use.
The teeth appeared to mesh with the mating gear,
installed the new pinion, reassembled and it worked fine. Not sure if it made a noticable difference in the output shaft speed.

To access the interior of the mixer, I first removed the single screw holding the cup-shaped part at the rear. Then I removed the 4 large screws on the under surface of the mixer head. Next I removed the bright metal ring around the planetary gear area by prying it off. I then pried the dish-shaped part off the shaft using a large-bla ... Read more ded screwdriver. This exposed 5 screws on the circumference of the planetary gear. By removing them, one can pull up the gears and see into the area below. I found the worm gear had fractured. By removing 3 screws at the base I extracted it for closer inspection, checking for any loose pieces. Beware of the jelly-like grease. The replacement part goes into position, and one then follows the steps in reverse.

Tried new brushes but alas it looks like it was a controller. Wife needed it asap so Ii bought her a new one. Service and delivery were quick but couldn't wait for a second part to try and repair it again.

When I took the back cover off I found two parts that "could" be the problem. The speed control plate was cracked which explained the spotty working. I ordered both parts and installed them very easily. The parts fit perfectly and resulted in the mixer working perfectly. I can't say enough about the excellent parts. They were perfe ...

I decided to update the motor brushes in our KitchenA id mixer even though it operated perfectly for years. After installing the motor brushes, you sent,I plugged the cord attached to the mixer into the outlet. I selected 1 on the speed selector and nothing occurred. The mixer would not operate. I then checked the outlet to insure ther ... Read more e was voltage present; there was voltage present. I again plugged the cord of the mixer into the outlet, selected 1, then 5, and finally 10, with no results. The mixer would not operate. Finally, I removed the motor brushes I had received from you and installed the old brushes that were originally in the mixer, plugged it in the outlet, selected 1 and the mixer operated perfectly as it did BEFORE installing the brushes you sent.

followed the emailed instructions from your company
worked perfectly
thanks

Really no help from Kitchen Aid sources; but phone call to PartSelect solved the problem. Kitchen Aid repair line didn't even know the part #! Thanks to Part/Select, Christmas cookies are being made.

just inserted the new wire whip

After stalling the mixer while mixing dough I found that the motor still functioned but the blade didn't move. I basically took the mixer into my shop along with a digital camera to record any complicated disassembly procedure I might have to deal with for reassembly and proceeded to disassemble the mixer. Once apart, I cleaned the mixe ... Read more r parts, removed the broken worm gear and bracket, and got online for someone that carried the replacement piece. PartSelect sent the replacement within 3 days and now it works great again.

dissassembled mixer and replaced gear

I removed the decorative band that covers the seam by removing 1 screw. I then removed the top portion of mixer by removing 4 square head screws. You will then see the gear housing in the front of the mixer. Remove the 4 screws holding that on. There are no spring that are going to pop out and you never know where they went, but be ca ... Read more reful because there is a lot of grease and a gear that it just laying in there on the right side. You will see the stainless shaft with a couple on gear cogs on it. Remove the retaing spring from the shaft and pull the top gear off, it may be a little snug. You will then see the dowel pin, mine was sheared off but I could see where it was. Be sure to remove the broken pieces. Use the punch to knock out the remaining pin. Replace with new pin making sure it is evenly exposed on both side of the shaft. Replace the top gear, then the retaining spring, the the gear housing cover, then the mixer top cover and finally the decorative band. Be sure to unplug before you start. These mixers are expensive and expensive to have someone fix them. I ordered 2 pins because shipping is a little high and the pin is cheap. I fixed this for $17.00 total and have a spare pin.

No nstallation required, simply attach.
Your website was the only one that made sense. I am blind and follow the instructions with a screen reader. I had no difficulty. It was much easier than this questionaire.
