The part numbers I listed above are for oil bath replacement parts only. You will need 1.980 size grease protector.
I am about to change from UFP Gold Series oil bath hubs to grease and have been reading as many threads on it as I can find. I found this in an old thread and would like to get clarification on this comment especially since it came from DABS.

The implication is that you don't need to pack the bearings with grease - just fill the hub with grease through the fitting on the bearing buddy. Is that correct?

Also, regarding the comment about the old oil mixing with the grease, it that accurate regardless of the type of grease used? I know that different types of grease are not compatible. Is that not true for oil and grease?
