cant get my nut off......

[elvis51]

wow so thats kinda a dirty title. anywho. im trying to take apart the ol ladies bike to rebuild for her, its a 73' murray monterey.

so heres the problem...
i got me a few cans of pb blaster and wd40 and sprayed the crap outta the nuts on the crank. got the first big nut off, whooo!!! got the washer seperated from the crank, whoo again! but heres the kicker. the last nut that has the bearing cone on it only has two flat spots on it and the rest of it is rounded. what can i use to get that d@mn thing off there? ive read that a big wrench would work, well the biggest wrench i have is about ( ) <---(thats my measurement) too small for the nut and i dont have a crescent wrench big enough. im borderline ready to just cut the freakin thing off but id rather save the a$$ chewin from the misses. any help would be sweet

can you drill into it a little...or cut a slot with a dremmel?? Then back it out with a tap...

pipe wrench or channel locks??

You could buy a bigger wrench. No such thing as having too many wrenches. I usually just use a big channel lock.

markm thats actually not a bad idea cuz the nut itself is pretty rusty and crappy so ill probably just buy her a whole new bearing set and nuts. thanks for all the assistance everyone. as for johnny nightwolf, your right you can never have too many tools!! EVER!

get a bigger wrench

 

[socal_jack]

The round ones usually have a slot that youcan use a punch to drift it off with. Had one like that on a Rollfast BB like below, yours might be obscured by rust

The chainring side is right hand threads btw.
