Jib Sheet Car sheave replacement

I have a '83 Hobie 16. My sheeves in my jib sheet cars are breaking apart.

I have not been able to find a part number or any information on replacing. IE has anyone drilled out and measured existing ones, and what did they replace the metal piece through the middle with.

Any ideas?

This was answered a couple times already. Do a search of jib cars. West Marine sells a Delrin sheave and also a Harken bearing sheave. The Harken part number was indicated in the post. Drill out the old one and use a clevis pin and ring ding.

The Harken Sheeve is the 160. Seems that the clevis pin we use is the 1/4 x 7/8 (HC 8020381). Sometimes we use the cotter pin, sometimes we use the lock ring - depends on buyer preference.
