So why replace them? If they may still be quite functional, what's
the point?


Shucks, I've bought old boats that were rigged with Harken
blocks... stripped off the rigging & thrown the rest of the
boat away.

You can replace the bearings in them, but that's only
desireable if they've been used hard for a long time & not
had the salt (and/or other gunk) rinsed out of them often
enough.

BTW it's not a good idea to use WD-40 as a lubricant for
these kinds of things. It only makes dirt cling to the
bearing surfaces.

They look a bit weathered from the picture which could be an issue for

acceptable level.
