Default Worm Gear lube question.

I have a "Professional" Kitchenaid mixer.
The worm gear drive is toast.
The grease was used separated into a black mess
and light oil that oozed out everywhere at the
seams of the body. The chamber the gear runs in
is not sealed so I don't think I can use oil.
What kind of lube can I use that do not separate?

I would use Fluid Film. It is food safe and stays where you put it but won't get hard like that yak fat they put in there. spray it on and it forms a light grease. That hard grease is the same shit they put in angle grinder gearboxes.

I had the same problem I went to the local oil supplier and bought "food grade grease" and the mixer has been fine since. I think I still have the tube, I will look later.

The silica thickened grease from McMaster should last the longest.

Bubba, there is supposed to be a gasket in there, I rebuilt my 5quart pro model, and it had a gasket. I picked up a broken 6quart pro model last fall when I helped a friend clean out her aunts house to get it ready for the estate auction, it has a gasket also. It needs a good cleaning and a new gear train.
Just remember not to overfill the transmission housing with grease, too much is almost as bad as not enough.

2/3 of the volume should be filled with grease, 1/3 air.
