Hobart A200 slipping

I am fairly astute at mechanical devices, but it has me stumped. I rebuilt unit, replaced old style worm shaft and put in new main shaft with diving mechanisms all new. It is slipping in first and second, works fine in third so I know it's not the worm gears. Help, any ideas?

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.

When you say lag and catch up. This may not be a issue. I have seen this with dough and a spiral hooks on all sizes of Hobarts the hook and dough get in a position to push the hook forward and the drive gears catch back up the hook. in fist gear on the 20 quart this is common for sure. but its normal. if you have a real slip from a sheared key it will not take long to where you can hold the planetary shaft with your hand and stop it. another slip that might be possible is if your mixer has the first generation worm shaft gear Assembly. when it is worn out it will slip you. this is the shaft that drives directly off the motor. you can tell if it's first Gen by it has a large spring on it. the tow later versions are all keyed to the shaft no chance to slip unless a key shears.

SOURCE: hobart A200 transmission issues

Your A200 was manufactured in 1942. It may well be time for an overhaul. If it were only noisy, I would suggest re-greasing it, as that would quiet it down somewhat. With 60+ years on the unit, the odds suggest rebuild time. Before you commit to that, take the top cover off the unit, remove two dust covers, insert a hi-intensity flashlight into one hole and look inside the other, look for excessive wear on the gears. If you see excessive wear, and still want to re-build then call for a Hobart tech and warm up your checkbook, OR, pose the re-build question to bigg t (the Hobart tech on this website). He may be able to help you out. ricardok45

SOURCE: hobart A200 mixer motor worm gear

sometimes you read of other problems and solutions and it puts you at the edge of your seat. in this case of changing the worm gear on the A200F was cake. when you drop the lower end (3/4 acorn and jam nut), pull out yoke (speed select handle) the center transmision shaft and gears pull right out.worm gear easy to change at this point. if you can change a motor bearing, then you can do this job. Note: change seals and bearings as needed,check all gears,keys and spacers for wear and if you go the mile take gears off drive gears, these are the 2 smaller trans shafts put in lath if you have accsess to one if not roll shafts on flat surface to see that shafts have no bends in them. Also remember when you put the bottom back do not over tighten the jam nut,hold and lock acorn nut, should spin free and have about .016 to .030 movement up or down. Lay out all part on cardboard the way they came out. should go back together easy.

Hobart 20QT guessing old a200 motor runs fine removed top cover to see but gears not working and mixer does not spin Any diagnosis Help greatly appreciated


The first vertical shaft has a brass gear that runs off the rotor. The ancient models had a spring loaded slip clutch built onto the gear. Upgrade it with a worm shaft kit which gives you a complete new shaft and fixed gears. I think it includes the upper and lower bearings. Maybe replace the grease if it has not been done. Or look for a sheared key on the worm shaft.

Hobart a200 will run just fine without anything in the bowl, once I pour my ingredients into the bowl, it wouldn't even mix the ingredients. Try all 3 gears.


Short answer: something is worn/broken inside the mixer's transmission.

Longer answer:

Since none of the three gears operate, the problem is most likely on either the worm gear shaft (probably the brass worm gear itself) or the "transmission shaft" (ironic name as all three shafts could be called transmission shafts). If you're up to the task of disassembling the transmission, which is a very messy task, you'd probably find the problem on one of the two smaller shafts inside the transmission. You'll most likely find either a broken key or worn brass worm gear. Both of these items may have enough holding strength to operate under very light loads (such as an empty bowl) but slip once a load is presented.
Also check the planetary key. Remove the planetary by removing two nuts on the underside of the transmission, where the attachments attach (careful, as the whole thing will drop once the second, thin nut is removed). You will find a long key on the shaft (or in the planetary gear, whichever one it sticks to). Make sure it's not broken, and re-attach the planetary.

Hobart Mixer A200 buzzing. The motor not moving


Have you try to run the motor without engaing of worm gears? The worm gear 15T assembly need to remove in order for motor to run freely. check worm gear attach to motor shaft for any damaging.

Small screw and nut?


By turning the screw cw or ccw it adjusts the clearance on the worm shaft assembely,in other words if the mixer is noisy by adjusting this screw you can quiet it down.

Hobart A200 diagnosis


the first A-200's have a worm gear drive that will slip when old but also when mixing dough somtimes the dough will push the mixer aherad of its self and look like its slowing but its just catching up. if you have a old worm shaft it will have a spring on it is how to tell. it is replaced with a shaft that is all keyed and has no slip or give unless a key shears.
