4KB25G1XTG3 KitchenAid Mixer - Instructions

Remove the top cover , inspect the gears . In my case the worm gear and the gear follower worn out . I removed the damage gears and the old grease , clean the inside and reinstalled everything . Now , the mixer is working good again.

remove the cover,take out four screw from gear box,remove the gear box,clean all gears,then you see damage gear,replace it ,install new grease.

opened the mixer.. all screws in kitchaid are the same so not to worry... opened up and replaced the gears... and put it back together... diagram helped in that front and rear bearings of connecting gear are the same # on diagram it is easy to confuse when you put it back together, but the item number and description of each helped make sure it was in the right place. Otherwise... time to fix would have been less....

took mixer cover off, took gear box cover off, removed gears, replaced gears, replaced covers, made cookies, no problem!!

Open the case, removed gear cover, removed planetary drive shaft and gear, replaced with new planetary and reassemble.

Following Replacement Part Youtube instructions, I disassembled the mixer and found what caused the sounds and prevented the mixer from operating. The worm follower gear had been ground down by the worm gear. I found that the shaft from the planetary gear had not been adequately greased and siezed preventing the worm follower gear from turning. The worm gear is obviously made of harder material and thus, was able to wear away the follower. I appreciate the your help which saved having to replace a perfectly good/expensive mixer. Thanks.

Looked at the schematic for this model on Parts Select. Removed Aluminum band screw, removed the 4 screws that hold the top of the mixer. Lifted the top off. Removed 4 screws and lifted the gear case. Removed snap ring and took off tapered gear. Removed pin and removed worm gear. Picked out the metal, in the grease, from the old worm gear, using a magnet then inserted new worm gear and put it back together in reverse order. There was plenty of grease and didn't need to add any.

Took housing off, removed computer board and disconnected speed control assembly from board. Soaked plastic slide in hot water and freed up mech. Discovered a crack in plastic slide from forcing it. Ordered new assembly and installed. TIP: Keep slide clean of substances that will jam it by cleaning occasionally with water. For a complete cleaning you will have to remove it. Total of 6 easy to reach screws.

Took mixer apart and then the gear compartment. inspected components. Replaced the worn gears and re-greased the new parts. Put the gear compartment back together, tested the operation of the unit and then replaced the rest of mixer, re-tested and declared victory.

Great experience. Reasonable cost. Quick delivery. Would certainly use PartSelect again

ordered the part and put in in with the help from the instant repairman

Open the package with the new screw and it looked like the screw was wider. I tried it to see if it goes in and as long as you screw it straight in, there was no problem.

I sent for a new thumb screw and screwed it in where it belongs and now I can use my other attachments.

the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install
