[TowerTalk] Need Help with AN Wireless Thrust Bearings

[Robert Harmon]

Doug,  

Jim nailed it.   That is how to set up a bearing with an eccentric ring.  I have the same 
bearing only it is made by SKF and has a four bolt mounting flange.  Don't forget to cinch 
down the set screw on the side when you are finished.
Here is a SKF tutorial on setting up the eccentric ring also.  You don't need to use a hook spanner wrench
as they show.  Just tap it around with hammer and drift pin.
