Hobart A200T - agitator shaft replacement

Hi Bigg T, I read through your other solutions - Kudos to you for being so helpful and valuable!!

The little key on my agitator shaft broke off, so I am replacing the entire shaft. How do I go about doing this? I have the assembly pics/parts list and I am wondering if I need to get at it from the top by removing the transmission? Or can I get to it from the bottom? THANKS!!

    i found that a little key is holding it in place on the center shaft ... how do i remove this key?

  • leftychang Nov 27, 2008

    a little more digging and i found this thing is called a "gib key" or "tapered key" and they make special removers for them ... problem is searching google has me coming up empty ... any idea where i can get this tool?

    or any other ideas on how to get it out? i read that some car guys weld a bolt to the gib key then pull it out, but id like to avoid pulling the TIG welder out for this one (if i can)

    my shaft broke and i need to know how to take all those gears apart

    Hi, usually the key comes right out, do you have the planetary hub off already? and is the key split, meaning did it sheer in the shaft?

Lefty, It's called a tapered pin. It can be removed by using a punch which is a bit smaller than the pin. This tapered pin can only be driven out from one side. Put a bit of WD-40 or some other penetrating oil in the pin area then figure out which end of the pin is smallest. Gently tap it out with the punch and a hammer, only use as much force as necessary. Only replace the shaft if it's badly damaged. You may be able to get at it by removing the four screws on the attachment hub. Remove the hub and see if you can get at it from there. If you can't, you should be able to get at it from the top. If you do replace it, you might consider replacing the shaft bearing and the bearing on the planetary shaft. If you find this solution helpfull, please rate it. Good luck. ricardok45

Ae200 hobart mixer agitator beater shaft

Sep 02, 2015 | Hobart Food Mixers

Professional 600 575 watts 6 qt. beater stem is loose and lets beater drop onto bowl.

b68be83b-c0cb-45d6-8d74-337f1cf098bd.jpgThe part you see is called the planetary, it has two shafts, the long one is called the center shaft and if it is falling off you need a new planetary, the second shaft (shorter) is called the agitator shaft (the beater attaches to it, if this is the culprit then1 you are not attaching the beater correctly2 the locking pin that the beater attaches to to hold it in place is missing3 you have way too much "gunk" build up on the agitator shaft and the beater is not attaching correctly4 if the beater falls into the bowl with the agitator shaft still attached you have three additional problems a) the snap ring a top the agitator shaft has broken off or come off which in turn means that
b) the gear at the top of the shaft has come off and may very well been knocked around and possibly damaged beyond future use which means that you will need a new one and also
c) the shaft pin that holds the agitator gear in place has come out or been broken also
the fix is easy and your parts cost $ will be from $30.00 to $80.00 dollars depending on which parts you need. Now before you get palpitations, cost are listed as a possible need
1 new planetary $30.00, you may not need
2 new agitator shaft and gear assembly $27.00, pretty sure that you need but maybe not
3 new gasket $6.00
4 new gear grease $6.00 KA says 2 oz. (don't buy a 2lb (26.00 bucks) can when you only need 2 oz).

Without more clarity or a picture I can't help further. but before you start tearing you machine apart go to the KA website and get a parts list for your mixer

let us know how you fare on this or better yet get us a little more info and we can help more.

Drive it out with a punch and hammer. It's best to take the planetary off the machine so you can support the shaft. If not it puts a lot of unnecessary stress on the bearings and other parts.

There is a knob that the whisk attaches to from

Hi ALLENJ740, I believe the ‘knob’ that you’re referring to on the agitator shaft (rotating column) is called a ‘groove pin’, and you should be able to replace it yourself. Before you get started, it would be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at:
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 4 & 5, titled: “Case Gearing And Planetary Unit” which shows you an exploded view of all the mechanical parts and assemblies for your mixer. Locate Illus. No. 40, Agitator Shaft, Part No. 4176067. Unfortunately the ‘geniuses’ at KA didn’t identify agitator shaft ‘groove pin’ for this model series...duh?
Sooo download this Repair Parts manual file K45SSWH0.pdf (341.41 KB) for a K45SSW model. The K45SS model and your K5SS model share the same agitator shaft part number, and in this manual Illus. No. 21 identifies the ‘groove pin’ (Part No. 9704677), which is the ‘knob’ part you need to replace.
You will need a punch drive with a smaller diameter than the groove pin, a hammer, steady hands and plenty of patience. Rotate the planetary agitator shaft so that the flush end of the groove pin with the agitator shaft is facing you (the extended part (knob) of the pin – or where it used to be - is facing away from you). Align your punch drive on the end of the groove pin and give it a good whack; repeat until the pin starts to come out the other side of the agitator shaft. Continue tapping until the pin comes completely free. Note the groves on the pin as you will need to orient the replacement groove pin the same way when you place it back on the agitator shaft. Just reverse the process. You’ll want to tap the groove pin home to make sure it’s securely in place. You don’t want it to come loose while mixing.
Here are five potential online vendors in no particular order:;;;; and (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.
Also, for future reference here are links to three excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble, troubleshoot, determine appropriate repair parts and reassemble your mixer to get it working again. Good luck. I hope this helps. Howard, Burke, VA

A200-T Hobart Mixer 1st speed have no torque

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,

good luck.
