Hobart a200 mixer won't mix

I took mine apart completely and reassembled everything and greased everything and mine is doing the same thing. I'm thinking, also, that it is the tightening of the top lock nut.

The Hobart H600 is a 2 horse power, 60 quart mixer, it can be used for many things in the kitchen. It can be used to make about any kind of food that needs mixed, wiped or kneaded. It works well in a pizzeria for all facets of making pizza from the dough, to shredding the cheese with an attachment, to a restaurant that makes mashed potatoes and fresh bread, to a full service bakery.
However, the biggest thing that you need to know is the capacity of the machine. As overloading the machine can cause damage that may be costly and take a technician to fix. I do not know what attachments you currently have so I will go over a few of them.

The main attachments are a Wire whip, Flat beater, and Dough hook. There are three different types a "D" wire whip (has many wires and is evenly spaced) this is used to whip egg whites, whipping whip cream, etc. The "C Wing" (has six tines in it) is used for items that are heavy for the D wire whip, like whipping potatoes or icing. The last is the "I" whip is similar to the D wire whip just with less tines. The flat beater is used to mashing or mixing examples are mashed potatoes before they are whipped, cake mixes that do not require whipping, batters and icing. The Dough hook is used for kneading dough examples are pizza dough, bread dough, etc.

The biggest thing when using your mixer is to know its capacity for the material that you are mixing. All though this is one of the bigger machines it still has limits. You should refer to this the following link for the capacity of your machine: https://my.hobartcorp.com/resourcecenter/ProductDocumentation/F-7701.pdf

There are also a few attachments that can be put on to the No. 12 attachment hub. A few of these are a vegetable slicer-grater and meat grinder.

First of all, I want to say that it is common for people to overload the A200 mixer when mixing dough. The owner's manual gives an extensive chart for various substances typical of what people may mix. Depending on the consistency of the dough, the maximum batch size varies, but as an example: 9 lbs. max with 40% absorption ratio thin pizza dough, 1st gear only, 5 minutes maximum mix time. I remember this particular batch size/specification because as a technician who works on these mixers frequently, I had a customer attempting to mix 20+ lbs. of that 40% pizza dough for much more than 5 minutes and didn't understand why the mixer would stall and why his mixer was so hot he could nearly cook eggs on it's transmission case. So, a word of caution (9 lbs. at 40% A.R. is approx. 7 lbs. flour, plus the water) about overloading these. If used to mix reasonable batches, they are excellent mixers and will last a lifetime (I regularly service 40-50 year old A200 model mixers that run very well).

If you don't hear any grinding when it's stalled (which would indicated stripped gears, damaged keys, etc. in the transmission) I would say you are overloading it. Many people want to say the motor is weak when the mixer stalls, but unless the motor has been repeatedly and severely overheated to the point of shorting some of the motor's windings, that's not the case. I suggest finding the recommended capacity chart from Hobart and abiding by it and you'll love your new mixer for years.

I'd say you're most likely overloading the mixer. This mixer, and others similar in size, are frequently overloaded by people making pizza dough. If you are making dough, keep in mind the A-200's capacity is 9 lb. of 40% A.R. pizza dough, mixed for 5 minutes maximum. If you need to mix longer, the batch must be cut down even smaller, but I don't even know if you're mixing dough.

Try running the mixer unloaded (i.e. nothing in the bowl) for ten minutes or more and see if it gets hot. If it still gets hot, the motor's start circuit (varies depending upon age of the A-200; Hobart used numerous motors in the A-200 over the years, incorporating different starting circuits) most likely has problems. If it doesn't get hot when operating unloaded, then you're probably overheating the mixer by overloading it.

Sounds like a combination of two issues.

1. In all likelyhood, the viscosity of the lubricant in the main transmission of your mixer has broken down and is now oil rather than the grease it once was.

2. The seal on the main transmission shaft is worn and the "oil" is leaking past it, resulting in drops of oil forming on the bolt head at the bottom of your planetary and dripping into your bowl.

Draining and replacing the lube and seal is a rather involved repair. To do it properly, complete transmission disassembly is required.

If it was my pizza business and there's just a drop of oil here and there ( 1-3 drops in the bottom of bowl in the morning ) I'd let it ride, keep wiping the oil away prior to mixing a batch and budget (apprx $500-$600 ) for a proper repair as it becomes worse over time. Unfortunately, it won't get better.

I'll add.

It's been my experience that D300's and pizza dough don't play well together. Be certain to calculate the weight of all your ingredients and then consult the capacity chart found here. http://www.kroslakbakeryequipment.com/pdfz/HOBD300.pdf

Stay within the guidelines and you should be fine...however your batches will be rather small.

Hope this is of some use.

You have killed it by overloading the bowl. Hobart recomends no more than 65% bowl capacity on doughs & 75% on batters or icings. Replace the motor or the whole unit

What you replaced were the contacts on the overload,correct?These 'heaters' look like springs?If so you have other issues.I'm a hobart tech and repair these mixers often.Are you mixing pizza dough?

Hi. You should consider a few things. They type of hook you use, can greatly affect your end result. If you're making a yeasted dough with a high protein percentage 12-13%, you should be using an "ED" hook, this is a spiral hook that has a sharp turn at the tip. You can find them on eBay for a competitive price. I believe that Hobart also sells them, but for a higher price. They are very good for mixing pizza type doughs, they also do an excellent job kneading the dough.

Have you checked the flour for lumps before it goes into the mixer? Have you tried sifting the flour?
Are you adding all the liquid and flour at once? If so try adding flour in stages to all the liquid. If you find that this solution helps you, please rate it. Good luck! ricardok45

Check the planetary.this is the bottom part of the mixer where you attach the hook.
You will see two nuts; make sure their tight as the planetary may have moved down.
