They can be replaced - I did it last year. I bought the replacement sheaves from RigRight - Part # SS Jib Box Sheave Replacement Kit: K-10658SK http://rigrite.com/Spars/Kenyon_Spars/4060-MORC.html

It is a bit a pain in the ass - you have to punch out the old pins and replace them with clevis pins that fit as tight as possible. Then you have to grind a bit of the mast opening away so you can get the box back in. It took me about 4 hrs to do it but it was worth it.

FYI - After doing it myself - you might want to see if you can find some ball bearing or nylon sheaves vs the Alum ones that are the replacement kit.
