i need help ,

how do i take my cranks off without a crank tool

I'd just fork out the £5 and buy a crank puller unless the crank threads are damaged, in which case I've had good success using a screwdriver combined with a 450mm adjustable wrench on the hex section of the screwdriver shaft to lever cranks off - this was for a well greased ISIS crank though.

and

how do i take my headset out :S

please help

Take the fork out and then either hit the headset cups from inside with a hammer and chisel or (Less likely to wreck your headtube) hit the cups out with a block of wood from the outside. Keep alternating which side of the cup you hammer in order to remove it straight - if you only hammer one side it will try to turn sideways in the headtube.

There's a specific tool for this job too, but there's less benefit to buying it...

cranks ... block of wood and a hammer

hit the cranks from behind should just come off , might take a few hits ..

headset ... take forks out take all bearing out of top cup (top part of headset), take all bearing out of bottom cup ( bottom part of headset)

then get a flat headed screwdriver and tap the top and bottom cups out using a hammer make sure u tap them out straight

hope this helps

To get cracks off - Try and hammer a flat head screwdriver in between the crank arm and bb cup, then try and leaver the crank off. If this doesn't work you could try hammer the crank off, but this isn't recommended as it can bend your crank arm.

To get headset out - Providing it's not an internal headset, dismantle the headset so its just the cups left in, then get a long flat head screw driver and slot it down the head tube (make sure the screwdriver is pressed up against the side) and as you slide it down you should eventually hit an edge that goes right round the head tube (This is the headset cup) so hold the screwdriver in place and hammer all round that edge and the cup should come out eventually (Try not to be too rough as it could damage the headset cup or head tube, but if done correctly it won't.)

I hope you could understand what I meant :P

This is the tool for removing headset cups:

There are also specific tools for fitting headsets (Headset press), removing the crown bearing race (The ring that sits on the bottom of fork steerer - a lot of headsets use a split ring which is easy to remove, but some cheaper ones are still on a press fit) and fitting new crown races (Again easy with the split race, harder with the press fit.

None of the headset tools are strictly necessary though. I made a headset press from some M12 threaded bar and a couple of 60mm round plates with a hole through their centres for the threaded bar and it's a lot neater than trying to hammer headset cups in. To remove bearing crown races some careful tapping with a screwdriver and hammer is fine, to fit crown races I have a block of wood with a hole through it big enough to fit the steerer tube and I use the block of wood to hammer the new bearing race on or hit it down with a hammer if the bearing race is very stiff.

I'd get this crank puller: http://www.chainreactioncycles.com/Models.aspx?ModelID=4939

It's suitable for square taper cranks with the end cap off the centre rod and ISIS/Octalink BB's with the cap fitted.
