5KSM180LEEBK4 Whirlpool Mixer - Instructions

I did some research and evaluated a modern day Kitchen Aid Mixer. Looked a the wire diagram and found out what items I needed. Ordered them from Partselect. Overall Mixer is updated and running. I made up some cookie dough with it. The Project took a few evenings due to rewiring the coils on the motor/armature and modifying the rear bearing bracket to hold the Phase control board (not OEM on 70's mixers). Then put it back together and adjusted the speed control.

replaced worm gear and wonderd why they used plastic instead of a stronger metal gear, unit works fine

dis-assemble, replace part, re-lube, reassemble, test good.

Followed the repair instructions from the manual. ...

I did notice that the replacement part had an extension on it that allowed for the gear grease to be "pulled up" onto the drive gear ( the one that broke), while the unit is running. This feature was not on the original part, but was obviously an upgrade design which was added after my particular mixer was made. I think that the extension on the bracket will help prevent the new nylon gear from binding and stripping as we use the mixer from now on.

I'm glad that PartSelect had the more modern part on hand, and not just an "overstock" from the original, inferior design.

Easy

We simply replaced the gear with the new one. It was very easy to install.

just as the you tube instructions said.

disasembled found stripped gesr assembly ordered and replaced went very smoothly. It would have been good to have info and acsess to the correct gear grease to use in a mixer / food grade but it worked out well anyway.shipping was very fast thanks

Disassembled gear housing and replaced worm gear/bracket assembly. The hardest part was cleaning and working around what looked like 2 pound of grease. I will contact you again if I need parts for anything. Thanks.

Followed web site's videos. One step left out of video.

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

replaced gear, and brushes.

Used youtube movies to disassemble the mixer and found that the gear was stripped. I kept the screws in labeled ziploc baggies so I wouldn't forget which screws went where. Once the part arrived, it was very simple to replace the gear. I regreased the mixer and then reassembled. The trickiest part was how greasy everything was! It was also hard to get the pin through the beater hub - I found a video that suggested using a very slim screwdriver to thread the hole before inserting the pin. This was the most involved part replacement I've done on my own, and it was very satisfying to get my mixer back in working order!

I replaced the phase control board because the mixer had only
one speed and was surging. I noticed from other posts that it
is important to note the setting of the speed plate before you
remove it in order to remove the phase control board. Also be
careful removing the associated 'slip-on' terminals as it would
be easy to damage the speed plate. If I ever do this again I
will go ahead and replace the speed plate, probably the cheapest
item to replace. The operation was a success and the mixer is
back in business. Thanks.

Replaced gasket and O-ring. Problem solved. POC (Piece of Cake).
