Whoops! Yes, the pulleys should be replace as well. That's per the
factory and other knowledgeable persons.

The cables and pulleys should be PM'ed every six months. You should do a
visual inspection and then apply a suitable lubricant to the cables and
pulleys. PreLube 6 is such a lubricant. It penetrates the cables as well as
lubricating the pulleys. That way you can use the same material on both.
TOWER TECH has PreLube 6 for $21.00 for 2 cans delivered to your QTH. I
have had an on-going series (7 parts!) on towers that includes crank-up
maintenance in my "Up The Tower" column in CQ Contest magazine. You might want
to check it out.
