I can't get my cranks loose!

[GrantYoungPhoto]

I cannot for the life of me break these loose. I'd like to save them, but if I can't that is fine too. Any help is appreciated! I should mention I am in between houses so I don't have all my tools! I'm getting some pb blaster in the morning to see if that helps. Is there something I'm missing or should these slide off without any kind of puller?

Looks to me like that crank requires a puller for removal.

There are two types of those style cranks, ones with a pinch bolt and ones without, the ones with a pinch bolt you can most of the time get off without a puller, but those ones will require a crank tool...

Just in my limited experience...

If there's threads in that big round part a a puller is needed.
Pb should help tho

I ordered a puller, I was hoping I didn't have to. I'm between houses so I just don't have my stuff around me. Oh well, I'll have em off Wednesday!

A dirty fix would be to use the bottombracket screws as pullers. Unscrew them will force the arm off. If the crank arm is close enough.

That's not the dirty way...
The dirty way is to loosen the arm securing nuts/bolts and ride the bike.
The arms almost always come off and if you don't loosen those nuts/bolts too much so the arms can't slide too far when riding you won't ruin anything.

Do I recommend this? Not normally but it works in a pinch.

Well I guess we all have our standards

Lol the first time I did my dirty arm removal went very bad because I loosened the nuts too much & 1 came off and when the arm popped loose I got hurt because it flew off. Ruined the arm and bb axel

I did that and they wanted more than the park tool puller so I just bought the puller and didn't look back

Be fair- that rusted mess could easily require more than a quick pull!!

put pedals on and track stand on it . see if that helps

I have placed a rag over the hole on pedal side and tapped it with a hammer on both sides. I worked for me. May want to give it a cheap try. If it is real stuck tap it top and bottom and side to side.

i think he already got the cranks off!
