4KN15C1XOB1 KitchenAid Mixer - Instructions

Replaced the worm gears. Original were ground down as if they were not seated correctly. Ordered the parts and swapped them out. I do not own a retaining clip removal tool. This was the most difficult, trying to open the clip using 2 needle nose pliers. It made the repair time longer.

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 the mixer apart many times. Grease all over the place. put new gears in still noisy. The worm gear must have been cut wrong. The noise still there. The part select sent out a new worm gear. I did not put it in yet. I put the old worm gear in and the noise stopped even though it shows wear. Have not decided whether I will put it in yet.I would also like to add that the people that I talked to at the this site were very very helpful and great just great---------

Just put on the new whip...exactly like old one.

Easily took apart and replaced gears. thanks

My husband removed screws and took top off mixer. Then he took out the gears and cleaned them from all the grease. After he did that he could see the gears that were all worn. We went on line ordered the new gears and in a couple of days the parts were here and he put them back in and greased it all again and put the top and screws back in place. Mixer sounds much quieter. Thank you.

followed directions given, removed all the old grease .did a short test run , then replaced with new grease. the reason the gear was striped was my fault mixing too much bread at one time. we have a coffee house and use the mixer every day.

Easy ; remove belt ( 1 screw ) remove cover , and there is the complete drive . I still need the top plastic cover which is cracked and broken where the bolts go through . Please quote this part .Conradt

Easy

Disassambled the gear-train.Removed all broken pieces and grease from gear case. Cleaned gear case and all parts. Reassembled gear-train with new parts and packed all with suitable quantity of new grease. Test run with variable speeds assuming working smoothly.

Removed the top housing.
Visual inspection revealed a cracked gear housing.
Removed the 4 screws to remove the housing.
Removed the gear retaining clip and inspected the gears and pin.
The housing was the only problem.
Noticed the plastic housing locating pins were missing and were stuck in the bottom aluminum housing pin receptacles. Carefully drilled out and cleaned debris.
Installed the new gear housing with gasket.

replace worm gear

Remove covers, open gear box, remove lock ring and gears to deterime which gears were bad. Remove old grease, install new gears and pack with new grease.

so easy to remove the switch. I first marked the wires, 1-2-3-4 and then removed them from the old switch. removed the old switch and replaced with the new one and plugged in the wires as per markings. tried it out before replacing the top and it works perfectly. no longer timid about effecting repairs on my own. the diagrams on the website were a great help. this is a great company to do business with. part was here in 3 days.

Could not get it properly installed. Had to take to a repair center for completion.
