His problem is not that he lives in Costa Rica, his problem is that he has been given a lot of good ideas and rejects them all. Costa Rica is served with delivery service and anything we can buy, he can buy, too. It may take longer to deliver, though. Additionally, the locals have been getting around these issues forever and there is probably a local guy who can fix it "good enough" for a reasonable charge. Or try bubble gum.
You didn't like the welding the nut on fix? Seems solid to me.
Only to add, if needed, take a 1/16" welding rod and gently tack weld the drive in zerk so it wont pop out.Me to. Drive in zerk would be second choice.
Hola Egon, yeah there was a big nut on it before for protection but I cut it off to be able to fix it. that square tube is dinky but better than nothing.
Thanks 2458n!
