The sheaves are replaceable but the block was not designed or intended to allow the sheave to be replaced. I have replaced sheaves on identical blocks in the past (for friends on a budget) but it took a while to find just the right sheave. On top of that I had to manufacture the replacement rivets. If you have all the right tools it's no big deal but for the # of manhours you would consume it would be better (and depending on your motor skills and replacement materials) safer to purchase a replacement block.
West Marine has a good assortment of replacement sheaves in their catalog with all the dimensions and composition materials noted.

|souljour2000||Thanks for the good advice...I may "give it a go" with a carbide drill bit and see if I can get into those rivets without a struggle...afterall..they are worthless as they are so its not like I am out anything except some time and expensive drill bits...and then the cost of the sheaves and the new pins in their place...the blocks are in great condition .(other than the 25 cent pieces of plastic each of them has...also known as sheaves...lol...If drilling out the rivets doesn't work l will have to check a local surplus sailboat supply depot called "Nautical trader"..been looking for a reason to go back there anyways...well see.....Thanks so much guys...|

The blocks in the photos are riveted and while the rivets can be drilled out and replaced with a bolt, it probably wouldn't be worth it.
When you are talking about a larger more expensive block, then it would probably make more sense to replace the sheave.
Having said that, it really depends on how handy you are and how much your time is worth.

Nice lookin' boat there. You can replace those blocks for $40 or so. West Marine has some Ronstans (Series 30) that take up to 5/16" line that'd probably do the trick. If your line is a bit heavier you might get all the way up to $60 to replace-and that's at WM-there's better deals out there.
Good luck to you. And you posted just fine, you were asking a question that you probably thought had a single correct answer. I'm sure that SailingDog did not mean it when he implied idiocy and I'm surprised he has not aplogized yet. One of these days I may even read that new to sailnet forums post, or swallow a bullet, it's a toss-up.

|sailingdog||One other point... buying new Lewmar Synchros means the blocks are far less likely to fail than are re-built home-made cobbled blocks that you'd have after drilling out the rivets.|

|souljour2000||I agree...thanks for all the help Sailingdog!|

|sailingdog||Given the prices for the smaller Lewmar Syncro blocks, I think you'd be better off buying them, rather than trying to cobble something together. THink about the cost of the replacement sheaves, pins and such, and you're pretty much at what the Lewmar Synchro blocks are going to cost.|
