Have a kitchenaid stand mixer Model # KP26N9XER the attachment hub is not turning correctly it only turns a liitle at a time with a thumping sound. Opened up looked at the gears and their are bits of metal inside the grease. The bottom arm on the mixer works fine. Also where can I find a manual on how to disassemble. The kitchenaid website does not have this. Thank you for your help

The bevel gear sits above the worm-follower gear. I think you mean the drive attachment gear.

I think I have the same, or similar problem. I ground a piece of meat that stopped it from working. The drive-attachment-gear turns if I push it in, but then it pops out. I am still trying to figure out what part is causing the issue - the drive attachment gear, or maybe even the worm follower gear.

Your guess is correct. Get it cheap on Ebay.

Most of the attachments for KitchenAid stand mixers are for use on all KitchenAid stand mixers regardless of series--as long as they have the attachment hub on the front.

1. Unplug stand mixer.
2. Place bowl lift handle in down position.
3. Attach flat beater.
4. Adjust so flat beater just clears bottom surface of bowl
when in lifted position by turning screw
(A) Counterclockwise to lower the bowl.
5. Just a slight turn 90 degrees in either direction.
Place bowl lift handle in up position to check clearance.
6. Repeat Steps 4 and 5 if necessary.
I hope I helped you.

Will it grind any wheat? I had a similar problem with the wheat overwelming the drive system and had to use smaller amounts of wheat to keep the system grinding. Do you have the feeder attached? I couldn't just load it up but had to feed a little at a time. Hope it helps. Favorable comments are apprieciated.

Hi Gail. Kitchenaid no longer has a Parts List for your model. This means that they consider it obsolete. Do an Internet search for parts. You may get lucky. Good luck!

That would be incorrect. If the attachment is for a hobart kitchenaid mixer then it will fit all models of kitchenaid mixers including the brand new pro series because the attachment port and drive gear has not been changes since 1925 or 6 when it was first introduce by the Hobart company.

You are correct, in the mixer head above the attachment hub is a gearbox, and there is a fiber gear meant to do just that should something similar happen, it can be replaced, I don't know price, but if you are careful, and fair mechanically, it is a straight forward replacement.

Why do I see oil leaking from the beater shaft of my stand mixer?
Some KitchenAid® stand mixers that are not used very often or have been tipped may experience slight oil leakage from the shaft or hub attachment. To avoid the oil leakage, KitchenAid suggests that you run the mixer weekly for short periods of time. Generally, the mixer may lose approximately X cup of oil before repair is necessary. The oil used is FDA approved and is not harmful to consume, should any get into the food that you are preparing.

I took mine apart and all the grease had settled down around the shaft in the housing due to lack of use,found no seal.Going to spread grease back up on gears,see what happens.I found this at KitcheAids web site.Good luck.
