Gear worm 9706730

I answered this for you in the blender dept, it will almost certainly be the fuse gear and that's machine cases apart to look in the gearbox.
Fuse gear part number is
4162897 Worm Gear
If you want to make the repair a little faster then the fuse gear already mounted in the bracket is another option
240309?2 Worm Gear Bracket And Gear
I call it a fuse gear, they call it a worm gear.

Something must be broken if the motor is turning and the planetary is not. It will be one of the following, we will start from the first point of contact with the armature
1) Worm gear broken (fuse gear) you say no teeth broken
2) Worm gear not broken but whole unbroken plastic part not gripping aluminium boss
3) Pin through worm gear broken or missing
4) Pin through centre (or bevel) gear broken or missing
5) Pin through small gear in planetary broken or missing
6) Pin through planetary hub centre shaft broken or missing

The most common ones in order of likelihood are, 1, 2, 3 and 6

We're can I find this gear

It is not a good idea to modify anything in the unit to make part(s)
designed for another model fit. The KT and KP models have different
part numbers for the motor. I still don't understand why do you have to
change motor in the first place, just because the Worm Gear Follower
has to be replaced. Something is telling me, you have just purchased
the wrong part (Follower). The KT2651x is similar to the KP26xxx
latest models and the Worm Gear does not come with the Follower.
(i.e. they are 2 different distinct parts)

I belieive i"ve found what you need at -the gourmet depot.net-click on worm gears on the list on left side of page,parts with pictures and listings will come up.I think you will want the kp50 series 5 parts

Here is the exploded parts list fr a K45, perhaps it will help you replace the stripped gear inside the gear housing. It is probably the gear which is driven by the motor shaft.:

It costs around $10 and can be found on the internet at places like:

It sounds like you have lost some teeth from your worm gear. This usually happens when the mixer has been overloaded. The teeth on the worm gear are designed to fail first to prevent more serious damage. To replace the part you will need to open the head on your mixer. The gears are at the front of the mixer packed in grease. It should be obvious that the worm gear has broken once the head is open. If it is not the worm gear, with the head open it should be easy to spot the problem. The gears are available as spare parts from several places on the internet. search for "kitchenaid worm gear"

When you replace the worm gear, you should be able to see if you need more grease. This will have been the "oil" you saw escaping.

no there are no adjustments . you must have bent the case just a little , i dont see any good news for you , sorry . i have worked on hobart mixers for years and you should get 5-10 years out of that gear

Very close; stand mixer parts (included accessories and manual only) can be accessed from this page:

Just select your mixer's part number (located on a sticker inside the base) and click the link for a list of available parts. You will have to create an account to see anything useful, but all they ask for is your name, a password and an email address. When adding items to your shopping cart, be sure to check the 'Select Item' box. The ordering page will ask for the usual info. Prices are reasonable, but beware the shipping cost!
