After viewing and listening to your video, my first guess would be bad bearing(s). The sound varies with the speed of the agitator, so the noise is at the speed of the transmission shaft or planetary area. These mixers use very common standard bearings. As such, they are available very reasonably from sources OTHER than Hobart. You will need to take the transmission apart in order to find and solve the problem. Study the parts manual in detail. It seems complicated, but once you understand it, it is logical. I highly recommend that you get a really good understanding of how it works and goes together before you start taking it apart though.
My fantastic guy just rebuilt my A200. He says it's likely that your back plate is slightly off center so that the center arbor is touching the windings-- any contact and the machine won't run. The tolerances are thousandths of an inch in there.
Drive it out with a punch and hammer. It's best to take the planetary off the machine so you can support the shaft. If not it puts a lot of unnecessary stress on the bearings and other parts.
There is a lever that is riveted to the shaft that controls the movement of the diving key. It may be broken. Email me and let me know what you found. [email protected]
Hi. I can't help you with your first question...But I can help with your brushes problem. Unplug the mixer With the two inspection plates removed at the commutator end loosen the two screws of the brush holder which are above and below the motor bearing cover, they're the only larger screws now visible. Note the markings on the brush holder on the bottom right side where you removed the inspection plate. Rotate the brush holder to the other mark. Set the brush holder screws. Plug in the power. and start the motor. It should now be turning in the proper direction, if not, make small adjustments by loosening the set screws, and moving the brushes until it starts to your satisfaction. Be sure that the set screws are tightened when you're done. If you need further assistance, post a clarification.
I have the same spec. mixer as you do.

Hi All. Since the original poster has not responded to my request for ML and spec. #'s, I'll offer a solution based on a spec.# 3943 for anyone with the same problem. This is an older model A200 with a solid aluminum gearshift lever.
Stop using the mixer!!!
The slow speed gear (1st. gear) is engaged by a "diving key". Over time this key can wear to the point of failure, or break entirely and will no longer engage. This failure only affects the first gear, allowing the second and third gears to function properly. If you can stop the mixer attachment by hand while in 1st. gear, then you have the above problem. The unit must be serviced. If the key has been sheared there is the potential for a broken piece of this key to get into the trans. grease and cause further damage to the mixer. For a Hobart Tech., this is relatively easy to repair as a minimum number of parts need to be removed in order to expose the diving key.
Call your local Hobart office to schedule a repair. If you've never done any repairs on this model, do not tackle this project by yourself. I you have some experience with this model goto the hobartservice.com website, register for free and then download the parts list. Ensure that you have the list for the 3493 spec.
Good luck!
