[TowerTalk] Pulley wheel (Sheave)replacements

[dan hearn]

JB are the sheave bodies shot or just the bearings? I replaced the
bearings in my TX472 with minimal trouble. The local bearing suppliers
found the bearings used by UST are obsolete but had sealed bearings with
the right OD. ID was too large but they had some bronze sleeve bushings
which were right OD for bearing ID and right ID for thru bolts. I
pressed out the old bearings with my bench vise and using a socket of
the right OD to pass thru the sheave hole. Put new cables on the tower
and everything back operating. 73, Dan, N5AR
