Once I removed the arms, I thought I needed one of these tools to remove shaft bit inside bottom bracket :-\.

Also how do you remove bearings, is it the same one as you remove one piece bearing cups.

The crank extractor is only for cranks that use a square taper (or similar) axle and have no pinch bolt. Bit of wood and mallet hammer also used to tap out bearing cups and the bearings themselves from the cups.
Post a picture up if you're unsure :daumenhoch:

Screw driver+rubber mallet is the only tools you need;)

Thanks for advice chaps I'll have to get frame out and have a look.
Yes I dont think the cranks were the pinch type, so would the tool below work?

I'll post some pics if I get stuck.

Heres a pic chaps.
1) I've removed the nut and washer off the crank arm.
2) How do I remove the crank arms (as you can see its not the bolt type on arms, like a spline inside)? :-\ Is it just a hammer, a block of wood against the arm and tap it off? :-\
3) Then how do I remove the bottom bracket? :-\
I know it may seem easy questions, but I've never dealt with 3 piece cranks before, as I only ever used 1 piece. :-[
HEYWOOD BMX:
Is there a thread inside the end of the arm for a puller tool? If not then one of these should work.
