Help removing non drive crank on a 30mm axle (not suitable for using crank puller)

We've got 2 and 3 legged pullers -

you need something to sit on the axle end to push against, and something to prevent marks on the back of the arm.

Also a bearing splitter will do the job, but can make a real mess, so only if you want to replace the crank on a beater, like it's got a damaged extractor thread on a taper fit.



I'd assumed that tapping the back with a soft faced mallet isn't working before stepping up to heavier stuff

- As for the coin method, less than quarter of a turn ought to be enough. Don't go too far!

Thanks mate, the problem with tapping it from the back is there isn’t much room to get in there and tap (because the cranks are fitted to the frame)

I’ve not tried anything yet as I wanted to be really careful and get peoples steer before doing anything

After about 10-15 mins of patient tapping with a bit of wooden dowel and a mallet swapping sides I’ve got them off with no damage to the cranks, axle, BB etc

I was worried I might have damaged the inside of the crank arm where it goes onto the axle but all
Ok!

Thanks everyone for your help - I’m so relieved
