Y25 Masthead Rebuild

[Syntonos]

Hello All,
Does anyone know the main / jib halyard sheave size? I need the diameter and bore size. I'll be pulling the mast on Syntonos next week and would like to have the them in hand to reduce my down time.
Thanks,
Syntonos

the mast manufacturer name would be helpfull. Rigrite has most hunter mast and boom sections with all the mast heads and specs. Gota know the mast section and general construction of the mast head though.

Thanks Bill, unfortunately the Yamaha mast is unique unto its own. Many of the fitting are specific Yamaha casting. I've just completed the rebuild and will be posting the endeavor soon.
