Rockman Posted June 19, 2011 Report Share Posted June 19, 2011 Maybe try heating the crank up, this should break any crap up and expand the metal. Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted June 21, 2011 Report Share Posted June 21, 2011 (edited) Spanner under the crank, so it supports it. Clamp this into a vice. Then use an appropriately sized socket / socket extension br that rests on / in the bottom bracket axle. Heat the outside of the crank with a heat gun and proceed to twat the socket/extension out and thus the bb. Edit: Or, cut the BB axle so only a small portion is left in the crank, and instead of the spanner, support the crank on a slightly open vice.

Matthew62 Posted June 21, 2011 Report Share Posted June 21, 2011 Thew threads are surely buggered on that crank now though so it's not like it's going back on another BB? Quote Link to comment Share on other sites More sharing options...
G_! Posted July 1, 2011 Author Report Share Posted July 1, 2011 (edited) thanks for the help but it's totally impossible , i have to buy a new bb and new cranks..i don't know with what money xd, also knowing how lucky i am, is very probable that the freewheel is blocked in the right crank Edited July 1, 2011 by G_!

JT! Posted July 3, 2011 Report Share Posted July 3, 2011 Like has been said, why keep trying, the threads on the crank are knacked so it's as good as useless anyway. Quote Link to comment Share on other sites More sharing options...
