This has to do with a lawnmower wheel but I'm posting here in case anybody has encountered and solved this very frustrating condition-
I replaced a 1/2" bolt on the wheel connection assembly and decided to be smart and use a nylon lock nut. The new nut went on the new bolt, nice and tight, about half way down the 3" bolt and then wouldn't "go no mo", neither back nor forth, lots of muscle, though not with a cheater bar, just an 8" crescent and socket, but the nut barely moves. It's as TIGHT AS [insert anal reference].
i'm thinking there is a reaction which makes the nylon turn into glue from the heat of friction but I can't find any data to confirm this. I'll try some penetrating oil and when that doesn't work I'll heat up the nut to soften the nylon (i think it was an ehow article that said +250 degrees).
I've used nylon lock nuts in the past, never had this problem before.
Thanks,
