I am writing this for my dad because he forgot to mention a very important thing. He said that the number one gear worked when he tightened the "stop nut" (flexloc). However that part and the other parts below it started to get warmer. He put grease below the stop nut to prevent the warming. Also, if the stop nut is loose, it still works a little but when you grab the thing that makes the hook go around, it stops it from moving. Do you know what could be the problem? Thanks for the help.I am writing this for my dad because he forgot to mention a very important thing. He said that the number one gear worked when he tightened the "stop nut" (flexloc).

Re:
Look also for rounded teeth on the gears themselves. Worn tooth corners can cause the gears to become unmeshed, & the shift fork may not be able to keep the gears meshed.

Re:
You are going to have to get your hands dirty and open the gearbox. Could be a selector problem or issue with the shaft.
If you need parts try Hobart themselves or get in touch with Ann at http://www.MaterialsTestingEquip.com
The selector would be the rod/shaft that actually moves the transfer gear to the selected speed gear.
If you are in any way unsure about what you are doing, do not take this machine apart.
If you look inside the gearbox and see how the internals move when you select a gear you should be able to see what happens when you select first. Look too see if the selector actually throws far enough to engage the gear. If not the selector could be bent.
I will see if I can find a service manual for the mixer to help you.The selector would be the rod/shaft that actually moves the transfer gear to the selected speed gear.

slacken the big acorn nut away from the bottom of the planetary and then tighten the lock nut to the acorn nut. When adjusted and secured, the planetary should have a little vertical play, maybe 1/16".
That will stop the second gear driving from friction from being too tight.
Jeff your almost there....it must be the shifter into third....it must not slide fully into third....check for wear marks on the worm gear....and try running it without the protective cover on to see how it changes from 1st, into 2nd, then third...that mechanisim if not engaging totally in third.
If the mixers are older the dive key shaft,spring or key are broken,if they are newer the key is sheared.Also check the nuts near the beater shaft and make sure there not too tight.
On the bottom of the planitary the part where you put the beater. there is two nuts. one lookes like a Acorn nut and a thin one above it. By the book the top thin one should be finger tight. Not wrench tight. you need a thin wall 3/4" wrench you hold the thin nut with iot and tighten up the bottom acorn up to the thin one and they lack against each other so not to come losse .on some mixers this thin nut tightend down will mess with older parts and bind the centersahft parts.
amy, depending on how old your mixer is there are 2 types of clutches for 1st gear.these could be your problems--a key is sheared on the shaft--shaft/gear is broken.the bottom part of the mixer where you put on the attachements is called the planetary,does it look like it has moved down?you could tell if the dough hook,wire whip,ect,ect is hitting the bottom of the bowl.if this is the case its just simply tightening the 2 nuts next to the beater shaft.if this is not the case you would have to dissasemble the transmission.let me know.
hi i work for hobart and these part numbers dont sound right.you have to make sure you have the ml number or spec number to get the correct parts.you can call your local hobart branch and they will help you further.
does anyone have a picture of a selector?
or can anyone explain what a selector does and what it looks like?
Thank you for the suggestion. I will try to do what you say. Thank You.
