Bottom bracket removal

[Chris S]

And make sure you are working from inside the BB using a socket and extension bar to reach in there. This way the nut/bolt is trying to tighten up as you turn out the cup.

Wouldn't that depend on whether the cup had a left or right hand thread?

 

[I like Skol]

I thought we were discussing the r/h fixed cup which I think is a r/h thread.

I always thought the r/h fixed cup had a left hand thread, so undone clockwise, ie, the wrong way. Italian threads are the opposite.

I think I am confused

Bicycles built to French or Italian standards have a normal right-hand threading for the fixed cup.
Bicycles built with British, Swiss or Raleigh threading use a left-hand thread for the fixed cup.

What is your homemade tool, Gunk? Picture, please.

It’s nothing fancy, just a cheap Chinese crank removal tool adapted with some washers, I use a breaker bar with a socket and slide a steel tube over the breaker bar for additional leverage, usually gets the slippery suckers out!

My bad

TBH I check the thread every time I do one and have an old set of cups in the spares box so I can be sure I turn the right way when trying to remove one from the frame.

I don't mess with 'foreign' bikes so I can remember which way to turn by following 'always turn towards the front of the bike'!

But is that to tighten them or take them out?

Well I bought a grade 8 bolt but they only had a regular nut. Also got 6 washers and used 3 inside and 2 outside. I had a ratchet wrench with an extension and 2 ft breaker bar for the nut. I started cranking and by golly after avwhile it worked. Having the breaker bar for leverage really helped. Thanks to all you guys for your help.

Gunk is your device 2 crank pullers or one?

I think it is to loosen and remove.

Yes, because that's what we were talking about! lol
