After I disassembly mine (7 original with the boat), I put the sheaves and rollers in my ultrasonic reloading cleaner at 160 degrees F and ran it for 30 minutes. All cleaned up good. Put them all back together with a good amount of winch grease. I expect they will be good for another 25 years. I found mine collection to be a mix of plain bearings and roller bearings plus the two new Garhauer Marine Torlon Ball Bearing snatch blocks.

So far, you've gotten good advice. They are Merriman blocks. I've had good luck taking snatch blocks apart, cleaning and lubing them. Do they have Allen head screws?

Soak them in suggested solutions, dissaemble, clean and lube. You may need to clean up the pin and hole with some ultra fine wet sanding.

As an alternative, look on eBay.  There's usually a bunch for sale.

    Greetings,

    INDIGO has a set of heavy-duty snatch blocks for the jib sheets.
    The bodies are solid black rummer and there is a trident stamp
    marking on the strap.

    One of the block's shieves is seized; looks like it'll need new
    pins and possibly a new sheive.

    Any ideas who may have made this block, are they still available,
    and where replacement parts may be obtained?

    Thank you,
    Richard
