[TowerTalk] US Tower HDX-689 Sheave replacement

[mikflathead at aol.com]

 Be careful doing that. Sometimes the grease in the bearing will catch fire.

NO!

At worst, a local machine shop can press a new bearing into a sheave.  Depending 
on the diameter of the sheave, your own resourcefulness and tool collection, you 
can often do it yourself with a large bench vise and some sockets.

In fact, with an aluminum sheave, I'd bet that you could heat the sheave up in a 
oven; put the bearing in a freezer; and the two components would slide together 
without a press!

Does that mean that the tower has to go back to UST to have such things 
installed? Just curious, before I look at spending lots of $$$$ for a tower that 
might need to have the same thing done a few years down the road. That could be 
VERY expensive!
