Hobart A200T General Info / Back cover plate gasket
Just got a used A200T. From the back plate:
SN 11-370-758 ML 33425 1/2 Hp 60 Hz
And with the switch plate off, inside the case, Motor info:
60-115 1 ML 17273A SN B894232
1) I understand the Hp and Hz, and I'm guessing the 60 115 1 is 60Hz, 115 volts, single phase, but is there anything else encoded in the model/serial numbers? Is there someplace to look them up? I can't find a SN list for these machines anywhere. It would be nice at least to know what year this thing was made.
2) If I can locate a service manual, what years would apply to this mixer - have there been any big changes, so that a manual from, say, 1995, wouldn't cover my mixer, but some other range of years would?
3) I took the back cover plate off to replace the screws. One of the heads was sheared off, and the plate was bent. According to the parts manual, there should be a gasket. What I had was a thin piece of old paper. How thick is that gasket supposed to be? If I put the cover back on tight, it seems to hold the spacer/bearings/shaft too far forward, and the machine sounds rough. Not quite grinding, but rough. If I stand the cover plate off with a couple of thin washers, it sound smooth again. Is that normal?
That's all for now Thanks for your help, and thanks for the website.

I'm a service tech for hobart,I'll type your serial number into our database and see what it brings up.The changes that have been made---older units use a mechanical start switch on the motor,the new units use an electronic start switch.the old units center shaft and gears have changed.the older units dont have bowl guards and the new units do.(this is a cage that goes around the bowl).The gasket that your talking about is just that--a thin paper.The paper wears and you get that symptom you describe and its normal.I'll get back to you.
I have the info on your mixer sanjuro.The original owner was value foods in sioux city south dakota.The year of the mixer is 1986.I have the info on your mixer sanjuro.The original owner was value foods in sioux city south dakota.The year of the mixer is 1986.

That's a bargain if it works. Apparently the date is hidden in the last three digits of the serial number, so February 1998 seems likely. The only sure way is to contact Hobart themselves. They have a great service department. I have used many Hobart mixers in my catering career.
I found this;
As the previous poster mentions, you can't decipher Hobart serial or ML numbers. I have about 30 pieces of Hobart equipment ranging from mixers to slicers to reach-ins to dishwashers and I couldn't make heads or tails of the numbers. Finally, I got hold of someone at Hobart who I emailed all the model numbers, serial numbers and ML numbers to and they emailed me back the month and year of manufacture. Even after I got the information, I still couldn't figure out where in the serial and ML numbers the manufacture dates were buried.
Do you really mean a 60 qt. mixer? That is industrial size and would be about 4' tall. Maybe a 6 qt. mixer? In either case, oil coming out around the shaft cover indicates that someone either over-lubricated the mixer or used the wrong viscosity lubrication. Has it been serviced recently? You might need to take it back to wherever it was serviced.
You may be correct about a loose spring. Check this:
Carefully lay the mixer on its back side to access the bottom of the mixer. Remove the cover screen covering the opening in the bottom of the mixer. Using an extension and appropriate socket, be sure the nut of the bowl lift rod is snug, slightly compressing the spring of the bowl lift rod.
You would need to provide the correct power to match the maching, or replace the rotor, stator, controls to match the higher voltage, and worm gears to correct the speed, from 60 to 50 Hz. Unless you don't mind it running slower. Cheaper to find one that matches your local spec..
You can go to www.hobartservice.com. select parts and type the machine ML number from the data plate. here are 5 different ML options, otherwise I would have given you the part number.
It will open an exploded view of YOUR machine's build, complete with part numbers.
You can then call your nearest Hobart dealer for a cost and availability. They are still a current model, and for their size, an excellent mixer worth repairing.
Hobart doesn't release their service manuals to the general public,however i'm a hobart tech and repair these mixer's often.If you need any help let me know.
take top front cover off see if motor is spinning when turned on? hum can come when motor is running or transmision jammed or motor has issue like capsitor bad or start switch inside motor bad.
Hi, it is hard to determine exactly what the problem is without seeing it, however, that mixer usually uses a capacitor to help start the motor, and a switch, or relay, that are in the back of the unit. You probably will not find any troubleshooting guide, Hobart does not give up information easily. You can take it to an electric motor repair shop, and they will easily be able to tell which of those is the problem, and will be reasonable in price. Your other option is to contact Hobart locally for service assistance. Maybe one of the other Hobart techs here can help you out more.
