Equivalent to Milwaukee type G grease

[Sanderguy777]

I just got an old Milwaukee 6020 sander/grinder.

They recommend type C grease in the manual, but then say that it was later updated to type G grease in their recent grease catalog.

I'm just curious if there is a cheaper option that would work (type g is hard to find, and then it's $25-30 for a pound!) Would basic moly grease work, or is that even cheaper?

Molybdenum black grease that not too thick and tacky be a good match to the type G I would expect .

So you're saying moly grease would work, but it can't be too tacky?

Or that none of it is tacky enough to be a problem?

 

[Mr_B]

Can't be too tacky or solid consistency, wants be a medium consistency (most grease will be classed number 2 for a medium consistency) very much like your average cv molybdenum grease .

Ok thanks!

What you're describing is John Deere Corn Head grease and it works in exactly the same manner. I've been using it for years on all types of grinders and polishers for exactly the reason you mentioned.

This may help.

9" Milwaukee 2-handle sander and whatever abrasive you favor, should make short work of things. Those sponge-looking abrasives do a good job, even on powdercoats.

Incidentally, I just am refilling my same tool 's grease vault, and I found out the G grade of grease as recommended by Milwaukee has been superseded in all applications calling for it, by type Y grease. 'The Word,' from Milwaukee's hot-line.

The type Y grease becomes liquid under load so it flows into the gearset, where a thick grease would just get flung-off by the rpm's, and not perform adequate lubrication. When the type Y grease cools it becomes more-viscous.

Thanks for the reply. According to the most recent Milwaukee documentation, all applications that require type G grease still do. There is no superseded number or recommendation for that.
For clarification, when you say "the word" from Milwaukee's hotline, does that mean that you spoke with a Milwaukee representative and received this information?
This would mean they moved from a moly grade 1 to a lithium grade 1. It's cheaper too.
Thanks

Yes, correct. Type G is superseded by Type Y

Type Y is what I bought 3 tubes of, Milwaukee brand, after the Milwaukee representative spoke with me on the phone.



This is what the fellow responding to me said:
Corn head grease-John Deere

Amazon.com

From the ebay website:

• Applications: Corn head gear cases, irrigation system, gear boxes and gear boxes requiring NLGI O grade grease

I suppose you can study the ratings and see for yourself if it's compatible.

Wonderful. Thank you for that clarification. The Milwaukee 6230 Deep Cut Band saw asks for NLGI 1 (one)
Both type G and type Y are NLGI 1 so I suppose it should work just fine. In fact, I bet any lithium or moly NLGI 1 would work fine. Many are quite a bit less expensive than the Milwaukee or Deer brands.
Thanks again.
