Front Bearing

1, Removed trim piece (1 screw) 2, removed cover (4 screws) 3, removed speed switch assembly (2 screws) 4, removed gear cover (4 screws) 5, removed and examined 2 worm gears for wear. Gear cover was badly cracked, don"t know if it was caused by a previous repair or by heat, as old cover is plastic. Received new parts and installed them, 2 bearings, 2 worm gears, 1 new cover of diecast metal and a new gasket. All repairs made with a #2 phillips screw driver. My wife then made bread, and it preformed flawlessly.

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.

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.

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.

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...

inspected and replaced worn components

Opened the gear housing and removed all gears. Cleaned out all grease. Biggest issue was getting the retaining ring; very tight. Gears were difficult to pull easily. In replacing gears they did not sit easily and took a little rubber hammer to re position worm and upper gear. Be sure to have the right grease for food devices and don’t under grease. And have patience of which I have a short supply.

took it apart. more grease all over. Put in all but one gear on the top. The noise is still there going to try to but the old bearings in and try again. I went back to the old worm gear and allmost all the noise stopped. I did put the new bearings in and the other gears. It seems that the gear on the worm gear was cut wrong. The noise was tear able. I tried the different parts I ordered one at a time. To find out which one stopped the noise. Every time I took a part I had grease all over. It took so long every time I put in a new part to put the trans back together again. I had grease all over.
