Question about Hobart A200 Stand Mixer

Hobart A200 Noise

I have a 1949 Hobart a200 spec 3943 that i am rebuilding the gears look to be in great shape from what i could see without removing them. I opened the transmission and removed the old grease. I then added new grease purchased from hobart.I also added grease to the planetary. It doesn't sound much better than it did before. The noise is like a metal on metal grinding sound. The url below is a website i created to document my project. When you put the mouse over the home button a menu pops out that will take you to a page called the unit. There is a button that will take you to a video of it running before grease. There are also pictures on the website that show the transmission gears. Even with grease it doesn't sound much different before. If there is anyone who knows what might be the problem please let me know. Thanks http://1949hobarta200spec3943overhaul.weebly.com/index.html

    here is a before and after grease video

  • Andy Doyle Nov 20, 2012

    If you look in this video here in the 2nd clip of the machine running 2nd gear is not much faster than first. Do you have any idea why that may be?

    From the short run times and close focus, I can't easily determine whether the mixer is running at its appropriate speeds or not. The bottom line though, is that if it is a transmission problem, the transmission must be taken apart to find the problem. IF the speeds are correct, it is possible that the noise is in the planetary. Try running it with the planetary removed and see if it is still noisy. Unless it is really quiet then, you need to have the transmission gone through.

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.

SOURCE: hobart A200 transmission issues

Your A200 was manufactured in 1942. It may well be time for an overhaul. If it were only noisy, I would suggest re-greasing it, as that would quiet it down somewhat. With 60+ years on the unit, the odds suggest rebuild time. Before you commit to that, take the top cover off the unit, remove two dust covers, insert a hi-intensity flashlight into one hole and look inside the other, look for excessive wear on the gears. If you see excessive wear, and still want to re-build then call for a Hobart tech and warm up your checkbook, OR, pose the re-build question to bigg t (the Hobart tech on this website). He may be able to help you out. ricardok45

My 20 qt. mixer has no power in speed #1.


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!

Looking 4 used parts A200


The safety cage kit is not cheap and you may not find a used cage. Why would you want to install used gears? They would have been removed from a mixer that has failed for some reason. Usually broken gears or shafts.
