Correct. And if one needs to shoot some kero or diesel through them to
clean em out..its not a big deal.

I those cases, I agree.


Or are you saying that you grease once..and once its filled..you
never grease again?

You can only get away with that on fully sealed systems - for a while.

Again..absolutely correct.

Ayup. FullySealed/MaintenanceFree = Replacement Soon Required.


Then we have things like automotive drive lines and U joints.
(Grin)..which catagory do those fall into? Hummm?

Theose which go "EEEE-URK, EEEE-URK, EEEE-URK" as they slowly drive
through the parking lot? Those are the old GreaseFree style, and you
pray you're not behind them on the freeway when one of them lets go,
especially the front one...
