What about mixing grease(s)?(6 posts)

What about mixing grease(s)?bill

(Gawd I'm so new at this)
I just set up my first headset -- well, the dealer installed the head tube cups, but I put in the bearings, etc. The bearings (campy) came greased with a white, presumably campy, grease. Following directions to "grease copiously," I just squirted a bunch of grease around the bearings before sealing it up. I used Phil Woods grease, which is, btw, green. I did not attempt to remove any of the white grease from the bearings as they were packed originally. Other than the color mismatch, which I'm sure will concern my seven-year-old daughter, is there any potential problem with mismatching greases? Haven't used it yet; I could call do-over.

Bill- YES! Mixing greases can be a nasty proposition. Phil Wood grease is a great headset lube, and perfect for bottom brackets as well. However, breakdown problems arise when it is mixed with other greases, particularly white grease that often comes stock on stuff like headsets. I'm not talking about catastrophic disaster type stuff, but you should probably take it apart and use one grease or the other, not both.
Not much of an issue in the HSKerry Irons

Since you're not spinning the bearings, all you really want is corrosion protection and something that won't be pushed away from the bearings (leave them dry). I've never had much faith in Phil grease - too high viscosity for my taste. I like something that "oils" as it's used so it provides a low friction situation and stays on the bearings. I've seen Phil grease in BBs where it looks like the stuff was just pushed out of the way by the rotating balls. But in the HS, none of this is much of an issue. No worries.

But what do I know? Seriously, I think it's perhaps a small theoretical problem but not likely to be a real one. This winter when you need to do something, take it apart and regrease with one or the other (secretly I agree w/Kerry on the viscosity issue, too, but I'd never question Phil Wood...).
