This is the deal jason,get a rubber mallet,mineral oil and a mapp torch.If you look at the guage plate this is the part that the meat/cheese goes on you will see 2 rods that connect it.Heat the rods up and put on mineral oil.Hit the guage plate down while turning the knob left then hit it up and knob to the right ,keep doing this and apply plenty of oil .It will be good as new!

SOURCE: Hobart C-100 mixer HELP!!!!
This is common there is a key on the shifter shaft and when you removed it the key came out and is floating in the grease in the tranny ready to destory the gears. That are no longer available at Hobart. if you want the shifter /switch plate off, remove the pin in shifter and the handle thats all. Hobart has a special puller I have two of them but you can use a H type puller to get to the pull threaded holes Mixer should be upside down on head to repair trans.

Hi, your mixer was manufactured in 1947. Hobart does not make public their service manuals. It sounds like the diving key is not engaging first gear with the spinning shaft. This is the ticking sound you hear/feel. This could be because of a broken spring in the mechanism that moves this key in and out, or the key itself has become so worn that it will no longer engage the first gear. The unit needs to be opened up to remove all old grease and oil, including the planetary. The condition of the grease in your description of the planetary, is a good indicator of the condition of the grease in the trans. Your unit probably needs an overhaul due to it's advanced age and grease state. Unplug the unit. You can gently remove the two circular metal dust covers underneath the top cover. With a good flashlight you can view the overall quality of the grease and the level of it. In an ideal world the grease should fill the entire cavity and no oil should be visible. Replacement grease should be Shell Darina EP-2 or Chevron ALC EP-2. You'll need 4-14 OZ. tubes of either type to do the job. The Spec. # for your unit is 3943 Look for drawing # PL-985 Once the cover is off the trans., it's relatively easy to get to the diving key once you remove first gear (the large round gear on top). Remove what you need in sequence, and replace in sequence. If you have a digital camera, take lots of dissasembly pics. When you are done, test in all gears by turning the motor cooling fins with your fingers in the normal direction of the motor rotation. Do not plug the unit back in until you've tested all speeds manually. Good luck! ricardok45

CE is the marking that shows its european conformant. I think the difference is mostly in terms of the no volt interlock switch. This means the KA style N50 bowl won't work with the CE models - too low.

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.
