Angle Grinder Grease

[danbrennan]

My Makita 4" grinder, over 30 years old, started making some not good sounds today. So I took it apart to check the bevel gears. They actually look great, but the grease looked pretty dried out. It's the original grease, I never thought to put fresh grease in it. What kind of grease is good for an angle grinder? My first thought was Lithium wheel bearing grease, but I thought I'd ask, repacking the grease seems like something others would have done.

I suppose anything is better than none, but a lot of the little gearboxes these days use 00 grease. Sort of a semi fluid stuff that actually gets in the gears but doesn't leak out. Tractor Supply or Rural King has it in some stores, not everywhere. In a quart bottle like regular gear lube.

You're right, that 00 grease is hard to find, I may have to order it.

I put a little wheel bearing grease on the gears for now. I'll see how it does next time I use it. Just starting it up for a few seconds after I moved the old grease around and added the wheel bearing grease, it seems okay.
