Hi
First gear used to start spinning very fast once in a great while and now first gear doesnt work at all, motor hums. Second and third gear work.
Any ideas? Thanks
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
Was the mixer overloaded?the clutch in 1st gear could be bad or a key is sheared.i would also check that the planetary didnt move down,this is the part where the hook/whip goes onto.you will see 2 nuts make sure there tight.im a hobart tech and very familiar with these mixers,let me know.
Could it be roller one way clutch
I have a Hobart a200 very old, it seems as though the spring is broken in the diving key arm, how do i get the old spring out and replace it with a new one? http://www.onesharpstore.com/catalog/item/3110109/8092234.htm

Hello, What an outstanding reference site. I have the same problem with the first gear not working on my Hobart A200. I have tightened the nuts on the planetary. Found that too tight puts first into second gear. After backing them off a little, it ran in first gear speed but with little or no torque. I can feel a light ticking if I hold the gear shift lever. Is there a schematic on how to get into the transmission other than the replacement parts catalog? I have downloaded that already. I'm an excellent do-it-yourselfer, so I feel that I could fix this on my own. Can I? Also, the "grease" in the planetary is more like a dried up paste. Is this normal, or can I scrape it all out and put in fresh? What kind of grease does it take. Serial number 885074.
did you ever get your answer? I have the wiring and manual but still the motor switch in the back (reset) keeps kicking off after running for a minute or two?
