how to remove a locktited crank nut?

[bikedudeomaha]

does anyone know of a way, besides heat, to remove a crank ring nut off of a crank that has locktite on it? i have 2 schwinn giant chainrings and cranks off of exersizer bikes that i have been trying to remove the chain rings so i can use the cranks. i have tried my vice with a big wrench but all i get is knuckle busters...ouch! anyone have a way of removing these?
thx for any ideas.

Heat is the only way I know to get past loctite, instead of a torch though maybe try a few drops of lighter fluid and light it.

worth a try...in a controlled setting of course.

One of those little propane torches comes in handy for bicycle repairing.

Definitely want to make sure you don't over do combustibles.

You should ask her what else she has hidden away.

I was going to say heat gun/hot air. You might also try one of those Weller Soldering Guns. You may be surprised how hot direct contact with the metal can get. Good with this.

correct direction ?

yes. had to check it out first.

Maybe putting the nut in the vice and turning the crank would work.
You could also cut the race/nut with a grinder. I've taken some seriously tight ones off with a 2' pipe wrench and a pipe to extend the handle. Good luck.

I throw them away and get new ones. You can make a new crank work in an old schwinn.
