Thats what we did Tab - the puller we had to hand just shredded it as it was in so tight. Plus the metal is so thin I guess. We've scored chisel lines on the inside of the crank in the process but that isn't an issue as the new bearing is held in well and nothing is deformed.

Next time go prepared with more chisels if needs be I guess?

We did also try the grease idea Andy, but it din't budge one tiny bit.

Maybe we were just unlucky this time around. That Burton Power one looks worth getting Manoj - thanks for the tip
