A good standard 90 wt oil is what is ok for the gearcase. This is an old email from a hobart service tech and they recomend a special oil ordered from them. So you can decide which you want to use. "EXXON SPARTAN EP-150 (6 oz)" in the M802 planetary. Hobart part #102973-13. This IS NOT a food grade oil. If you mixer is leaking you shouldhave it serviced. Service, parts , lubricants and information canbe obtained by contacting your local Hobartoffice in Pittsburgh@ (412) 788-5380. Steve Davis Field Engineer -
on a a200 there is no oil. this mixer requiers grease. if mixer is leaking oil it is because the grease is broken down .you have to pull tpo cover off mixer remove trans. parts clean out old grease clean all trans. parts reassemble put top cover back on .then make sure mixer runs in all 3-speeds before putting 1.5 cans of -47grease back in grease can be bought @any hobart office
You have a gear with broken teeth or one sliding out of place because the brass shims are eaten up. Hobarts have what is called a planetary, round head where the grease caps are, and there are no clutches for this planetary. These units are not made to change gears while unit is running (#1 problem of gear failure) (#2 is overloading the bowl) Hobarts need a really stiff GREASE, not oil. If you decide to take the planetary apart, get all the syrup out and replace with a stiff axel grease. It is a very difficult job replacing a gear & ALL the shims. The round head where the grease caps are can easily be removed to do this.
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.
Some of the N50's were packed with a white grease. It tends to seperate. So the oil portion finds it's way out. It sounds like it is getting into the motor case, and is running down the inside of the column. Hobart now uses a brown clay based grease --- Darina 2.
If the amounts are small, and the mixer is not excessively noisy, I wouldn't be concerned. If you wanted to fix it, the transmission would need to be removed, cleaned, and repacked. For a Hobart tech, 3 hours labor, $45 grease, plus parts.
man you got an oldie but goodie mixer!im a hobart service tech for 8 years and have only seen about two dozen,unfortuantly parts for these units are exhuasted.as for the sight glass they do become cloudy over time and you cant determine the oil level.use a heavy gear case oil.the only way of telling is to drain the oil or if the unit is loud you should probably cange the oil.
