5KSM180LEALB0 KitchenAid Mixer - Instructions

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 had 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.

Removed three screws and lifted out old part. replaced with new part

Repair is very straight forward. Remove the existing plate by removing the three phillip head screws. Use a regular screwdriver or knife to pop the plate off. (I cleaned the area while I was there but probably not necessary) Position the new plate with the screw holes lined up. Press down to pop the plate into position. Install original screws and tighten. You're done!

Removed old plate, screwed in new plate and works like new! Was so happy I wouldn’t have to replace my 30 year old mixer.

The brushes are located on each side of the tilt head of the mixer. I used a screwdriver to remove the screws, removed the brushes & replaced with the new ones. Runs great again!!

I watched a short video on replacing the worm gear, although I did not know what the problem was until I watched the video. after the video ended I took the mixer apart and found the problem located a parts number an placed my order. got the part in one week put in the new part in about 20 minutes and it work like new. and the price was very reasonable

The new part was too large for the replacement job, but we used the self tapping screws that came with the mixer and screwed them in from the bottom to open the holes a little more since the original screws were to short to hold the new plate. Then we replaced the screws with longer screws and that seemed to do the trick!

Followed your instructions from the internet and it was a simple fix. Mixer works great again. Thank You ..you made it easy!

Dismantled the mixer, took photos, and re-assembled unit.

I watched the university of YouTube videos, and followed their instructions.

I took apart the mixer housing and removed all the screws. The most difficult part was the two pins that needed to be removed with a metal punch. They were in fairly tight. The mixer came apart pretty easily and it was obvious which part needed to be replaced as it was broken and missing teeth. After replacing the gear and applying new grease for smooth operation, I simply put it back together and it has worked like new ever since.

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 mixer 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.

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 perfect.

dissassembled mixer and replaced gear

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.
