Replacing Mast Sheve

[Time2Go]

What would be the best way to replace the sheve seen in this picture
What's the best and least destructive way to remove?
What's the best way to install a new one
Boat is an O'Day Mariner 2+2
I'm thinking just drill out rivet and remove in the pieces
easy enough, replace the sheve, easy enough
but how would I then secure it in place
It appears to be some type of punched down rivet
(same on both sides)
What type of bearing would be proper?
This is my learning boat and all I have are hand tools and a cordless drill.
Thanx to All

You have it pretty much right. Drill out the rivet, insert new sheave from zephyr works, and bolt it in place.

if you cant find bolts long enough use some stainless rod with holes drilled in either end and split pins

Yes, and get some carbide tipped drills if you have to drill the rod yourself. Got a friend with a drill press?
