CRANK ARM REMOVAL HELP PLEASE?

[BADGER.BRAD]

Can anyone tell me if there is a proper way to remove crank arms from the bottom bracket, I wish to fit a two wheel chain set Which I already have to my Courier classic.
I have messed with loads of these in the passed but have always used the BIG HAMMER approach, as this bike cost more than a fiver I thought I ought to do the job right. Is there some sort of extractor?


Many thanks

Exact type required depends on the crank, but Park Tools do make a 'universal' crank extractor.

Same idea, same manufacturer, I have one of these and it takes off a Shimano crank OK

The hammer approach tends to bend things so they won't work properly afterwards - not good.

What was wrong with cotter pins anyway?

They wore and made your cranks go wobbly!

I just bought one of these.
Seems well made, and 1/3 the price of the Park.

I've got one of these, came from Wiggle and cost less than £6 - it works too!!

Edit - just seen the porkypete version, beats mine by 85p!

THere was me thinking this was some sort of right wing conspiracy to reduce the leftist nuumbers here

Well - yeah. But you got to use a big hammer to get them out! (And they cost next to nothing so you could put a new one in when you needed to).

I chucked out the remains of a packet of them that was at the bottom of my bike bits box a few weeks back. There were three left in it and it had 8d written on the side!

Amazing some of the rubbish in there, rusty ball bearings, screws, a bent crank, non-metric nuts, a couple of very rusty freewheel block cogs for a 5 speed .... made a lovely noise when tipped into the metal skip at the recycling centre.

But that's before you take into account SJS £2.50 p&p, as against Wiggle's free delivery. Ladeezangenlemen I think we have a winner!

I concede defeat.

But in my defence I had to put an order in to SJSC anyway for something that only they seem to stock.
