Just spoke with us towers and I have two 5 inch sheaves on the way. $135
each.....
The old pulley is fine...just the bearing is locked. Ray N6VR sent me a link
on replacement bearings on eBay...so ill check that out and see what a machine
shop can do for any future bearings I need replaced. Thanks..... Rich
