Hobart 450 chopper mixer

* Model? Check side plate or post picture so I can check.
* Usually leaks are at the bearing seal(s). Replace.
* Frequent seal changes (less than 1-3 months). Replace bearings and seals.
* Check shaft near bearing seals for pitting (rust) that will damage seal. Remove and have a machine shop refurbish part. If possible; replace whole part and bearings. (or rebuild gear box.)
* Call your Hobart service rep for a quote.
* Check and replace lost oil as needed until machine is rejected (inspector, quality control, maintenance, etc.) Be careful oil does not get into food product.

The oil seal is the resistance you feel. take a soft mallet or hammer with a soft drift and gently but firmly tap the stub shaft and it will drive out the oil seal in the hopper direction.The lower skirt of the tapered bearing is what contacts the seal so go slow.
Worked for me.

The oil leeking into your bowl is old grease that has broken down into oil and is getting past your oil seal you need to take out all of your old grease and oil replace it with hi-temp grease or a good grade lithium grease and replace your agitor shaft oil seal

Hobart mixers are NOT designed to change gears while operating. The Hobart planetary gears are like the transmission in your car but, without the clutch. Everytime you change gears while unit is running you are tearing up the brass spacers, gears & seals. Time to call a QUALIFIED service tech to come out & sell you another planetary or rebuild your old one, about $2K, Buy a Varimixer if you want to change gears while unit is running, they use belts. Another planetary premature failur cause, over loading the bowl. Batters & icings- 75% bowl capacity, Dough 65% bowl capacity.

can buy hobart bowls from lots of places, or use the correctly shaped kitchenaid ones, both fit.. i like the lip and thickness of the hobart bowls, bought mine from globe equip.. do u still have the service manual, if so i would be real intrested in it, please

bring mod#, and ml#, to any hobart office in your area and they will hook you up

Hi,I'm a hobart tech and repair these mixer's often.If you see oil in the drip cup then the center shaft seal in the transmission is worn.If there is oil near the transformer then the motor shaft seal is also bad.Hobart doesnt release their service manuals to the public but if you go to their site www.hobartcorp.com you can register for free and get a parts manual thats helpful.If you need help with the repair let me know,i can step you through it.

There is a website called onesharpstore.com, It carries parts for the hobart 30 quart mixer. I specifically saw the bowl and hook attachments as well as others like beaters and a cheese and vegetable grater. Hope this helps. And if you sign up I think you can even request a full catalog for your machine.

Yes A-200 are number 12 I would find a hobart grinder they will have a big H in the casting on the neck get one with a stainless pan and stomper to push product down the throat. If you wait on Ebay and put it on your watch list they do come along. look for no rust. Make sure it has the big H in the casting. the other after market ones seem to not last long like the metal wears on the worm and hub to fast. also you always know where to get a piece if you need it if its a Hobart. not so with the forign jobs.
