[TowerTalk] Pulley wheel (Sheave)replacements

[Eisinger]

JB-

I didn't see the original thread so am not sure of the overall condition of
your tower pulleys. I recently went through the same exercise and, after not
being able to find suitable replacements, took my sheaves (from an old US
Tower TX-472) to a machine shop and they were able to replace the bearings
for me.  For some reason, finding bearings that will fit the sheave is
easier than finding an entire replacement unit. I had the same experience
with US Tower with them not being willing to provide much info or even sell
me replacements.  After replacing the bearings, my sheaves were as good as
new.

Here is what I found out regarding replacement sheaves for the EZ Way
tower.
     First off,  Jim at Applied Mechanical Devices  was of little help,
He did fax me a sheet of their available sheaves but this was only a
copy out of the Mcmaster-Carr Catalog.
  Sava Industries of NJ who specialize in wire rope sheaves do not have
anything close to the size needed....I discovered that the sheaves are
all too thick for the application on an EZ Way Tower. US Tower was not
really even willing to help but did say the pulleys they use are all 5"
I checked with several other sources all with the same result...
  So I am stumped on this one.......unless someone out there has BTDT
and lets the rest of us in on where to find these sheaves it looks like
they would have to be custom
made
Anyone else out there with suggestions ????     I know from receiving
off list inquiries for info that  there are more than a handfull of hams
who are in need of these
I tried
