Question about Food Mixers
Can you confirm the model number and where the oil is leaking from?
Hobart make a 4246 and a 4632, but I am not familiar with a 4642

you can call your local hobart branch for the part number,but you use lithium grease in the unit.in order to change the grease the transmission needs to be opened and so does the planetary. i service these mixers alot i work for hobart.if you need any more help/questions let me know.

Hi. Your A200 is in need of service. The grease's lifespan has expired. There are two ways of doing this. First, the expensive way. Call for a Hobart Tech to come and service the mixer. This will take about 4-5hrs to service at a rate around $100.00usd per hour, plus the cost of parts. He/she will need to change all seals, remove old grease and oil, check all bearings and gears for excessive wear and replace as necessary, this includes the planetary gear.
Now for the affordable solution. Unplug the mixer, remove the top cover. Gently use a small screwdriver to pry off the two circular metal dust caps found on the transmission housing, use a good flashlight to determine, through these openings, the quality, quantity and condition of the grease inside the transmission case. If there's a lot of oil you can remove much of it a bit at a time by using a wire coat hanger to which you can attach bits of cloth to absorb as much oil as you can. Once oil is removed, add new grease through these same holes until full (Chevron FM ALC EP-2, food grade lube). Run the mixer for a couple of minutes to distribute the new grease. Fill to the top once again and replace dust covers. Remove planetary, clean, inspect change seal and re-grease.
OPTION (mechanically challenging) You can do a more thorough job by removing the trans. cover completely, removing the 3 gear shafts inspect all bearings and gears, change seals on mainshaft and planetary. Remove old grease and oil, clean gearshafts and gears. Parts drawings are available from www.hobartservice.com It's free to register and then locate your parts drawings. Be sure that you have the correct files for your Model #, ML# if there is one and Spec.#, all found on the info plate.
When disassembling, take a digital photo of every step and lay the removed components on a piece of cardboard in the removed sequence. These practices will become valuable during re-assembly.

SOURCE: Oil leak
instead of putting a gasket on tell him to take out all of the old grease out that is what has broken down and turning into oil causing a leak and if he can repace the seal around the agitator shaft replace the old grease with a high temp bearing grease or a good quality lithium grease

You're right, it's broken down grease. The A200 doesn't have a rubber seal to prevent this from leaking, either. That's normally OK, when the grease in reasonable condition, but when it breaks down bad enough, you see what you're seeing. The grease needs to be changed which requires disassembly of the transmission. It's quite a job (and very messy) if you're not familiar with it, but if you're interested I know I've read (and may have written one) instructions on disassembling the transmission on this website. If you decide to do the job yourself, be sure to remove the attachment hub (comes out to the inside of the transmission) and clean the passage well.
