Converting to oil bath and Timkins in the next couple days because of issues like this.
3,000 miles on the bearings that came with my disc conversion kit and and one of the outer ones is disintegrating. Can't trust any of them, they all have to be replaced.
Lots of Pro's and Con's back and forth, many old wives tales and anecdotes energetically expressed, but for me it came down to this:
The only time you know your greased bearings and seals are good is when they are in your hands.
Having to re-pack every 6 months and worrying about if the seal blew out when I used the zerk is not fun for me.
