I now have it tilted over. The cables look fine, but I am
going to apply Prelube 6 to them. The pulley's look fine,
but there is no way to really test the bearings since they
are under tension. From reading TT archives, it appears that
it would be a huge project to detension the cables just so
I could spin the pulleys. Can I lubricate them in place?
With Prelube 6 or "3 in 1" oil? Any suggestions?
If this is a modern US Tower, the pulleys have pressed-in sealed
bearings so there's nothing to lube anyway.
And it's hard to tell if many of them are not turning because most of
the pulleys are hidden.
And yes, replacing the pulleys is a daunting job, definitely not for
the faint hearted. Personally I wouldn't worry about it.
