Today i tried to change the front sproket but the nut didn't want to turn ! It is really annoying.Is it possible that the owner before me could have had it glued , or something like this? I really tried hard to unscrew it.First with 150Nm of force, then 250 , finally with a very powerful pneumatic key.What can it be? If it's glued with somethink like Loctite or something, is it any way to unscrew it ?

 

I used a air gun at like 150psi to break mine loose

 

I used a 6' cheater bar on my 1/2' breaker and that nut had no chance.
They are tight as hell, make sure you torque it back on the same way.

 

but if i apply an enormus force , don't i risk to destory te axel ? For exapmle breaking it?Cose that why the mecanic at the workshop didn't applyed more force... He said that is my decision if i want to apply a really big force... risking to destroy the axel...[sm=boohoo.gif]

 

The Mechanic is an idiot. What do you think the mechanic is going to do?

Just make sure you have bent back the locking nut, if it has one, and give it some muscle.

 

yes thats very true....bend back the lil part

 

i bent that washer , but i am affraid not to break anything around there....[sm=smiley13.gif]
So i should go for maximum force , a? [sm=smiley25.gif]

 

Yes! I told you that I needed a 6 foot extension on my breaker bar to get enough leverage to loosen mine. That little puppy is on there and you need to hit it hard to get it off.

 

and how did you managed to keep the backwheel locked? By the way... in unscrews by turning left , right ?[&:]

 

turns left....and put her in gear
