Hobart A200 noise
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.
