Question about Hobart A200 Stand Mixer
I'm wondering if you can help me diagnose a somewhat loud Hobart A200 mixer. It is an older model, serial #794389. I have not tested under a full load, but below are videos of it without a load and kneading a small (5lb) dough. The noise on high (3) speed is most pronounced and sounds like a bearing but more of a tick at speed 2 and a more continuous rattle at speed 3 than a whine. Any idea what might be causing the noise? There's very little play in the planetary shaft sideways but a little movement up and down... I might be able to measure it with a dial gauge but it's too small to estimate by hand. I was told that it has been sitting idle for a few years and I'm wondering if I should pull the transmission and repack it with grease. How difficult is this to do? The exploded parts list is impressive and I'm curious if re-greasing is something a mechanically inclined engineer could do? Would you be able to post some instructions?
Your mixer was built in 1942 and from the sound of it, it's been without grease for some time. Before you dismantle it, try adding new grease to it. This is the less expensive and less time consuming approach. The grease product to look for is Shell Darina XL EP-2, Try to find a local Shell Distributor and see if they'll sell you about 4 tubes of 400 grams each. This grease is compatible with most other greases, so you won't have to remove the old grease before you add the new stuff.
Remove the four screws that attach the Hub to the body of the mixer, pull off the hub. You now have access to the transmission area. work the new grease into the cavity, try to get as much grease as you can toward the back of the compartment. This will be a very messy job unless you have, or acquire a grease gun that the tubes will fit in. Lay the mixer on it's back and let gravity help you to get a lot of grease down through the hub opening. Keep adding grease until you've greased up to the hub opening. Grease the hub gear and then re-install the hub. Raise the mixer to vertical and start up the mixer, letting it run for a couple of minutes. Stop the mixer and shift gears,, once again start the mixer and repeat this procedure for the last gear. Listen for the sounds it was making before, they should be silent or at least muted. If it's still making loud noises, You may well have to take it apart for an overhaul. Dont overlook the planetary gearing, this gearing is not bathed in grease like the trans. Remove the planetery assembly, clean and inspect the planetary gear and the large ring gear in the mixer body. Regrease both and re-assemble. Your mixer is now as quiet as it will get short of a complete overhaul. If this solution works, it has only cost you a few bucks and a bit of time, making this. solution a good one, unless you still have the major noise issues.
I f you've found this solution helpfull, please rate it and Good Luck! ricardok45

The sound you are hearing is most likely from the Internal Gear a gear that the planetary gear rides on while mixing -- this gear may not look warn, but it is needing to be replaced along with the gear on the beater shaft. Replace both of these gears -- the internal gear and the planetary gear that rides on the inner rim and you will not hear that noise any more!

You may have stripped the clutch you will have to take it apart and look at it or you could have broken a key either way you have to open it up
