KP2670 KitchenAid Mixer - Instructions

took off the strap band around mixer, took off the cover (4 screws, took off gear cover (4 screws) took off the retaining ring(used pliers and screwdriver) took off upper gear, took out retaining pin, took off lower gear (becareful to grab the planetary assembly as it will fall out after you take out the retaining pin) cleaned out all of the gear grease (the teeth that were missing were in it. replaced the planetary assembly, lower gear and retaining pin. replaced the upper gear, replaced the retaining ring (used screwdriver and hammer. you have to spread the ring with end of screw driver so it will fit on the shaft then tap lightly with screwdriver and hammer to get it down to the keyway for the ring.) replaced the gear grease with NEW grease, reaplaced the gear cover, replaced the mixer cover, replaced the strap band and plugged it in to test it. IT was quieter than before and works great. i spent less than $30 to repair my 10 year old, out of warranty, Kitchen Aid Mixer. much better than the $32.00 to ship it to factory repair shop and get an estimate to repair. I needed it to make a cake for my nephews wedding. I had my parts in 2 DAYS!!! it was a great experience over all.

The transmission housing was cracked and one of the bearings was broken. I replaced both of them, but the mixer really didn't sound any better. So I replaced the gears in the transmission, and while that was better it still wasn't correct. I am going to replace the other bearing and the planetary shaft and see it that aligns everything a bit better. I believe the problem is the way the gear on the end of the motor shaft is working with the worm gear, the bearings are not keeping the correct spacing. Hopefully, the new one in the rear will fix the problem.

removed top casing, removed old switch and sensor,and replaced with new ones. It was just a matter of a half dozen screws and unpluging 4 or 5 wires and then reversing the process. Couldn't be easier. thank you

Removed the cover. Removed the gear assembly cover.. Extracted the C clip with a tool. Removed the bevel gear. Pushed out the dowel pin. Used rubber mallet to push the shaft off the worm gear. Replaced the washer and the worm gear. Used a 1/2" diameter PVC, 3" long over the shaft and on the gear to push back the shaft through the gear with rubber mallet. Pushed back the dowel pin. Reinstalled the C clip. Replaced broken hub bevel gear. Added more grease. Placed the gear cover with 4 screws just tight enough to hold the cover but still allows movement. Turned the mixer to the lowest speed. Allow the cover to self adjust so that the gears have the smoothest sound. Tightened the screws while while maintaining the smooth sound. Turned off the power. Replaced the cover.

The KitchenAid is "old school" in that it is held together with simple (but very stout) bolts and screws. I removed about 10 such fasteners, slipped off the gear retainer, and pulled it out. On Sunday, a very nice customer service rep helped me order the right part, but I did the rest on line in a matter of seconds. It shipped on Monday and arrived on Wednesday. Took about 10 minutes to put everything back. I REALLY WISH everything was this easy in 2012!!!

I looked on line found the product sent in information and 3 days later was in my mailbox,great service and ease of ordering. thanks marjorie

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.

removed the cover as stated in the e-mail and followed their recommendations on how to do the repair, the hardest part was removing the retainer clip, job went smoothly. thanks

First of all, go to the web site and download the schematics of the model #. It will show all the parts and part #s. Secondly watch a u tube video of the actual strip down process of the professional 600 series stand mixer. With this knowledge, do one of two processes 1: strip down the machine, remove the gears and check for defects- order parts. Or 2: replace all the parts( little money) and have a totally refurbished , smooth running mixer. I kept the good used gears for spares. I replaced 90 % of the internals ( including motor) and have a smooth running machine. I initially burned out the mother 2 months after initial purchase, sent it back under warentee, and received it back . Wen I stripped it down 10 years later, there was very little grease in the gear housing. This is what probable ruined the gears. Use plenty of grease in the housing and gears. The grease is one of the most expensive items, but you can't find it anywhere, so order it, along with everything else, from Parts Select.

Removed top cover, remove snap-ring on shaft, slide top gear and worm gear off. Clean all the grease out and clean parts. Installed new worm gear and parts. Repacked with new grease, careful not to much, leaving room for expansion.

Easy repair that replaced the variable speed switch. The broken switch only ran at high speed. To replace the mixer would cost at least $500. The new switch was $45 and was an easy install. I marked the four electrical leads with a Sharpie and loosened the two screws holding the switch. The repair was super easy. It was like heling an old friend recover from an illness.

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.

Remove screw and nut from back of mixer head to release the silver name band. Remove the exposed four cross head screws, (two each side), and lift off the motor and gear cover. Wipe excess grease from gear wheels to expose the retaining ring clip at top of vertical gear shaft. Using small nose circlip pliers, remove retaining ring and bevel gear wheel to expose shaft pin and worm gear. Support the shaft from below and remove pin. Lift off worn worm gear wheel allowing shaft to drop down. The horizontal worm gear shaft can now be lifted out taking care to keep assembled. Carefully clean old grease from all gears and from the gear housing, (note that broken pieces of the old worm gear are in the old grease. Repack housing with fresh high performance grease recommended for worm drives. Cover new and reuseable gears with grease. Reverse the process to reassemble the unit.

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.
