tris Posted July 29, 2008 Report Share Posted July 29, 2008 you need to buy a crank extractor. it locks into the threads on the cranks and drives the crank off the BB. They can be bought for about £6.00. Quote Link to comment Share on other sites More sharing options...
James Shields Posted July 29, 2008 Report Share Posted July 29, 2008 i had this problem on my base, with my hussefelt cranks. easiest way = rubber mallet. once i had the left side off, the drive side just came off. next time try greasing everything up but not to much. james Quote Link to comment Share on other sites More sharing options...
Headley Posted July 29, 2008 Report Share Posted July 29, 2008 try using a rubber mallet first but if you havn't got one/can't get hold of one a block of wood and a normal hammer should do the trick. If that fales a crank extractor will deffinatly get them off, just make sure you get the right type for your cranks (taper/ISIS) because I snapped one when I tried using a taper extractor on ISIS cranks.

Ben John-Hynes Posted July 30, 2008 Report Share Posted July 30, 2008 But a square taper one,And if you ever decide to go isis, keep the square one and just use it normally, just stack some 5p coins into the crank.that works for me! Quote Link to comment Share on other sites More sharing options...
