Kitchenaid accolade 400 how to access worm gear for this model

Sounds like the speed control, easy to replace and the model is on the bottom. Simple google search to find part

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.

Make sure that the bowl is fully tightened in the bowl lock. If this does not solve the problem it may be that the lock disc itself needs to be replaced or that the amount of dough is more than the dough hook can handle.

The number in your question (9706529) is for the worm gear.
What is the model Kitchenaid mixer you have?

Remove the Gearcase Motor Housing (1) & the Transmission Housing (7)
Remove the 2 screws (23) holding down the Motor (2) and lift off way from
the Worm Gear (17). Test run the motor by itself at different speeds.
If it runs fine then it's time to inspect all the gears in the Transmission
Housing(7). Remove all the brown Grease covering the gears.
Pay attention in particular to the teeth of the Worm Follower Gear (19).
(the Bevel Gear (21) sits on top of this gear)
They should not be worn out or chipped. If they are then this is the source
of the noises you're hearing (the Worm Gear is grinding away the teeth of
the Worm Follower Gear). Once the Follower is replaced, your mixer will
be just as new again.
Please Note that this replacement is not an easy task. You need the right
tools and don't use a hard object like a steel screwdriver to pry out the
Planetary plate (15) from the beater shaft. Before re-assembly, use only
fresh new Food Grade Grease from Kitchenaid (the old grease may contain
metal filings from the worn out gear that will damage your new one)

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)

has the breakdown of the parts. Item 8 is the controller board and item 9 is a sensor which monitors the speed. If either one is fried it will run wide open and then quit.

The most common part to fail in this mixer is the worm gear:

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!
