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!
