Question about Hobart Food Mixers
Check the spring pin that locks the motor shaft to the main drive gear in the gear box. You should be able to turn the motor from the back at the cooling fins and watch the shaft spin in the gear, that is if the pin is sheared. That is a common problem. if you plan on keeping this machine for a while, i recomend that you spend a little more on a quality spring pin,

Sounds like the shear pin on the planetary shaft has sheared off. Has the mixer been subjected to a heavy load. Remove the planetary and see if the shear pin is intact otherwise you may have to open up the transmission.

Hobart mixers are NOT designed to change gears while operating. The Hobart planetary gears are like the transmission in your car but, without the clutch. Everytime you change gears while unit is running you are tearing up the brass spacers, gears & seals. Time to call a QUALIFIED service tech to come out & sell you another planetary or rebuild your old one, about $2K, Buy a Varimixer if you want to change gears while unit is running, they use belts. Another planetary premature failur cause, over loading the bowl. Batters & icings- 75% bowl capacity, Dough 65% bowl capacity.

You have a gear with broken teeth or one sliding out of place because the brass shims are eaten up. Hobarts have what is called a planetary, round head where the grease caps are, and there are no clutches for this planetary. These units are not made to change gears while unit is running (#1 problem of gear failure) (#2 is overloading the bowl) Hobarts need a really stiff GREASE, not oil. If you decide to take the planetary apart, get all the syrup out and replace with a stiff axel grease. It is a very difficult job replacing a gear & ALL the shims. The round head where the grease caps are can easily be removed to do this.
