Technical Leather Hub/Grease Seal?

Is treating them required before use? If yes, do you smear same bearing grease the day before install, an oil like that of Neatsfoot maybe…?

 

or squirt a little motor oil on them? and use immediately.

btw, you get big bonus points for using leather seals

 

Lol. I was surprised that they even come that way anymore considering where I purchased them.

 

I always soaked them with motor oil

 

Super Tech 5W-30 it is then.

 

I always just wiped some of the bearing grease on them and installed the drum.

I remember when most of the CR seals (Chicago Rawhide) where still leather up into the 80's.
