What type of oil is used in hobart-h600

The transmission has to be disassembled for this repair. I believe your best option is to contact your local Hobart office and have them do it.

on the hobart h600 we use 120 oz of 140 weight gear oil.

H600 uses Mobilgear 634.

Mobilgear 634
128 FL OZ or fill it to the line in the sight glass.

For most applications once every two to three years should be fine.

the part# for the oil is102973-71, that can be bought @any hobart office in your area

take off top cover, where the front screw on top cover threaded into is the fill plug for the trans.drain oil replace drain plug , also ck. sight glass if dark or cloudy replace,@this time.trans. oil can be bought @ any hobartoffice the part# for the trans. oil is102973-66 that will come in a 128 oz bottle you will not need all of it. pour a little @ a time till oil hits line on sight glass. please vote thanks

there is an oil case drain pulg under the top by the clutch, you can drain the motor housing through there, \
i have used 5w30 in a pinch
but it would be better if you ordered hobart oil from the website
its cheap but very very good

Needed to know which part to open up to add or change oil on Hobart Mixer h-600

You can use a heavy weight gear oil or call the local hobart branch for it.To remove oil----Look under the mixer where the beater shaft is in the back and you will see a three quarter inch nut,remove this nut and drain the oil then put nut back in.To fill the unit remove the top cover screws and remove the top,you will see a long hexagon nut in length,remove this and grab a funnel then add the oil---be patient it takes time to fill as the oil is heavy.
