Turbo Crank Arms Stuck

<< < (5/6) > >>

theRuler:
heat
tip a kettle of boiling water on the crank arm
the ali will expand quicker than the steel spindle
then see if you can tug it off, or knock it off with wood and hammer

failing that try a crank puller, but be careful it doesnt put gouges in the arm

ORB:
Derv is the best releasing agent there is.

To get the arms off, a crank puller is about the only decent and reliable way to do it.

Dont buy one of them 1.99 ones from the ebay, i snapped one in a matter of seconds on a set of Sugino crankage.

Go to a cycle shop and buy a half decent one.

Hot water will also help.

theRuler:
try the hot water first
then give some licks with a hammer and drift
once the seal breaks it will fly off

FuNMoNsTeR:
Cheers m8... I have ordered the plus gas off ebay. I am also looking for a crank puller. Its the square tapered spline one i want yes and not the osiris?(whatever that is).
 My polisher should be here Monday i will let you know what its like... i got it on Ebay from a guy in Wales its called a Lapidary set and comes in a case. Its ideal for polishing small areas etc.
