4KB25G1XBU5 KitchenAid Mixer - Instructions

remove the old screw and screwed the new part in place. I like your link because it shows a picture of the fixture and you can find the part you need real easy. Will order from you again when I need it.

Removed mixer motor housing by removing 5 obvious screws.
Removed plastic transmission cover by removing 4 obvious screws.
Down load parts exploded drawing from PartSelect.com
Found the worn part by the shiny teeth on the large gear.
Found the large worm gear on the drawing and ordered the gear, and associated bearings. Did not need the seal.
Removed worn part, assembled new gear and beargings in same manner as the worn part, and placed new part in mixer.
Replaced transmission cover gasket.
Repacked grease from transmission cover onto the new gear.
Replaced transmission cover (4 screws).
Replaced mixer motor housing (4 screws).
Replaced mixer trim band around the motor houseing joing. (1 screw).
Plugged it and and it works, good as new.

I took all the grease out of the top of the mixer. Saw that the gear was worn. When the new parts came I put as much grease in as was in before. Put it back together and it worked like a champ.

The parts I received from PartSelect were higher quality than the original parts. The bevel gear and housing were originally plastic. The new ones are solid metal. The machine sounds and runs better than it ever did. The drawings from the website made this really easy. This will be my first choise for parts from now on.

I removed the motor assembly from the mixer. This left the stand assembly. The raising lift arm had to be removed by unscrewing the set screw, and then the lift arm was removed. I replaced the plastic arm bowl lift by sliding it over the lift arm, and then I had to remove the spring with a clip washer with the pliers, and replaced the spring back on to the new part. Total time about ten minutes for the actual fix, and about 45 minutes remove and reinstall the 12 screws that held the motor in place. It was well worth my efforts. The mixer arm works perfectly now.

the hardest part is removing the retaining ring (didn't buy pliers)after that it is very easy, remove ring, top gear, center pin, bottom gear,worm gear(was removed first)the grease is pretty nasty,clean off the old grease and put it all back the way it came apart,with new grease.And then PRAY !!!!!!! THANK YOU PARTS SELECT for your wonder smart staff.

per e.g. and put cover on and secured screws. Pluged in unit turned it on and it worked for 25 secs then went full speed and shut down.. repeat this several times got same results. Put old unit back in and it worked for 2 days then same results. I now suspect coil on shaft is defective. I'll order that and see. Unless some one knows of another problem.

Took off cover, marked leads, unscrewed two screws and replaced circuit board (speed swith unit). This one was really easy.

I removed the old screw with a hand tool to avoid injuring my hand. I then used my hand to install the new screw. Piece of cake. Ordering from Part Select was was a breeze. The only minor issue was the part cost $4.33 and shipping was $7.25.

Unscrewed stainless steel Kitchenaid band, removed screws holding down the main housing to get to the speed control panel. Removed two screws from to release the speed control panel, replaced the panel with new part, and replaced all the screws to the main housing, and stainless steel band and it worked like new. So easy, and it only took about 15 minutes to repair.

sat on the kitchen table and with a screwdriver started to disasemble the mixer,hardest part was taking snap ring off (easy after you buy snap ring pliers)as gears were lifted off noticeable wearing was present on all parts. the bearing housing on the gearcase was broken lose, the only major expense. the other parts are not expensive so i decided to renew all parts. glad i did felt proud of myself when job was done. would do it again Joe

1) Unplug power cord from outlet.
2) Remove #2 Phillips screw from metal band at the back of the mixer.
3) Remove band and set aside.
4) Remove 4 #2 Phillips screws that connect top of mixer housing with bottom.
5) Gently pry up on top housing to remove.
6) Remove two screws hold original speed board in place.
7) Old board and new board may have board components in different locations.
8) Lugs are marked Motor 1, Motor 2, Line 1 and Line 2.
9) One at a time move a lead from old board to new, making certain you match the leads up to the printing on the board. e.g.; Motor 1 must go to Motor 1.
10) When all leads are moved install new board with the two screws.
11) Put top back on and install four screws.
12) Clean and install stainless steel band.
13) Plug in and bump start to check for proper operation.

At the back of mixer is 1 screw that holds metal band. Remove to reveal 4 screws that hold top half of mixer. Inside locate transmission housing remove 4 more screws. Inside housing carefully scrape away grease and broken bits of gear. Take out worm gear drive shaft wipe off and inspect. Clean up grease inside tranny locate keeper ring on vertical shaft spread and slide off use 2 screwdrivers to jimmy gears up. Replace with new parts put back together and use fresh grease. Not too hard at all and alot cheaper than a new kitchen-aid.

I am VERY impressed With this site . I am very disappointed with Kitchenaid. I paid more for this mixer than I paid for my first car especially when you ad in the attachments. I was mixing dough when I saw what looked like Small metal shavings in the dough... Then I heard a clacking sound so I turned off the machine and cussed...I got the screw driver and took off the top and was really surprised that on a machine that retails for over $550.00 dollars that the gear housing is PLASTIC...And this one had a crack down the side... So I took my trusty Phillips #2 and removed the housing to see that the front Bearing was broken as well so I got on line to kitchenaid and they are determined to continue the process of Shafting you and I with the prices of thier made to fail (Quickly) parts and lubricants.. Thank God for PartSelect. I got a better housing for half the money as well as a Bearing. Now I wish this were the end but remember I said that there was metal shavings in my dough? Well since I was going to have to replace the lube anyway I took apart the planetary gear as well and found that it had been shaving metal from the underside of the upper main housing .. After cleaning I checked and the lower bushing wasn't seated so it had been doing this since I bought it and I didn't know.. So I got a C Clamp and pressed it to where the thing should have been to begin with. If you are going to be working on the thing I suggest you tear it down completely and clean It thoroughly and inspect EVERYTHING closely... I have been eating metal shavings for who knows how long...

I ordered the switch control. Opened up the top part of the mixer using a Philips screwdriver. Then I unscrewed all the screws that connected the old part. Disconnected the wires, connected them to the new panel , screwed everything back together and i was done. It was that easy.
