K45SSBFOB0 Whirlpool Mixer - Instructions

I removed three screws, pulled off the old base plate.
Put new base plate in place and replaced the screws

Fairly easy if you have done it once before.

Easy

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

had to replace the outlet strip and relocate the mounting screw,,,,wiring cord to the mixer was super correct and had to simply follow basic wiring (black to black,,,silver to silver,,,green to ground) ,,, the cord came with the correct mounting bushing already on the cord. Thx a bunch!

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.

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!

I had a sourdough batch get into the space where dough hook attaches and it got so stuck that nothing - not hot water baths, not pliers and screwdrivers got the dough hook released. I had to open up the mixer following partselect you tube instructions and replacing the parts. What was confusing to me at first is that my 45 year old mixer had an extra screw on top of the shaft that no longer is there for newer models. It took me longer than I am willing to admit to figure that the extra screw is not the result of me skimming the instructions - the original shaft and dough hook went to a friend who broke it attempting to disengage the two parts (the dough turned out to be a very strong form of glue!). The piece is working like new. I preferred the agitator shaft with a spring to hold the end piece tighter, but the new set up without a spring works just fine.

I simply inserted the new beater into the mixer to see if it scraped the sides of the bowl. It fit perfectly and didn't scrape the bowl like the old one did.

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 back cover, disconnected the 2 push-on connectors, removed ground wire screw. Reversed the process to install new cord.

Removed the rear cover to inspect the speed board. Replaced motor brushes and noticed the motor body nuts were loose and 1 was completely off. Cleaned up speed board and replaced the motor body nuts, tightened with nutdriver, adjusted speedboard governor screws and with new motor brushes worked like a charm. The very rough sounding motor noise was gone and the mixer has not operated so quietly ever.

You tube has great instructions! I would suggest when you buy a part to let customer know that they need a food grade gear grease ordered to complete the reinstall of all gears and body parts!

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

replaced gear, and brushes.
