[TowerTalk] US Tower HDX-689 Sheave replacement

[Bob K6UJ]

That is discouraging to hear. I am hoping to order some spare bearings for my HDX589.  
I suppose contacting US Tower wouldn't do any good, they probably wont let us know the supplier for the sheave bearings.............
On the other hand I think I will all them tomorrow and see.
