need help - squeaky sheave!!

Good day, SN'ers!
I need some of the expert help I know only you can provide.

I've got a squeaky sheave on the main halyard of our C&C35-1.
I took the sheave box out last week, to try and figure out what might be the cause.
Here are my observations:
  1. 1. the sheave box itself is damaged, bent
  2. 2. the sheave itself is in good shape
  3. 3. the bronze/brass bushing is slightly wider than the width of the sheave, possibly causing friction betwen the bushing and the sheave box
  4. 4. there was no wear on the sides of the sheave, indicating no contact between the side of the sheave and the sheave box
  5. 5. the OD of the axle pin (.385) is quite a bit smaller than the ID of the axle bushing (.410)

What do you folks believe the most likely cause of ghastly squealing when this halyard is under load??

The bushings are actually made on oil impregnated bronze -- suspect replacement is in order. See Sheave Bushings & Spacers and order replacements. No more squeaks.

CLucas - thanks for your reply!

Everyone else...I have to say, I'm a bit disappointed in the response to this thread. Only 1 opinion??

Was hoping for a bit more input than that....

Don't let me down, folks!!
