YAJIB Posted June 16, 2006 Report Share Posted June 16, 2006 Hi i recommend that u get a cloth or something and put it round the inside of the crank and it with screwdriver or something softer if possible. Try hitting from the opposite side of which cranks got the cloth on and put the screwdriver through a gap in the fame and hit it and see if it comes off. It worked for me and didnt damage the crank so it should be fine. hope this helps Jay Quote Link to comment Share on other sites More sharing options...
ogre Posted June 16, 2006 Report Share Posted June 16, 2006 (edited) Wrap something round your crank(s), take the crank bolts out and hit the crank(s) with a hammer(or stand on them) while pulling up/away from whatever direction your pushing the cranks and they should come off.

pollocks Posted June 16, 2006 Report Share Posted June 16, 2006 for removing the crank when the crank extractor threads have been damaged i tend to find putting a block of wood behind the crank arm to stop you damaging it as a screw driver is gonna go straight through a piece of cloth when you hit it really and then tape it of gently hitting it and working your way round trying to hit more then just behind the crank arm and if you have some degreaser and wd40 or similar like easy free give it a squirt of easy free/wd40 and that should help to get the crank to slide off once the cranks off if you have used lube to aid this give it a wipe over with the degreaser so as the cranks will seat again nicely onces you refit them and not work loose again Quote Link to comment Share on other sites More sharing options...
