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.
