Stuck 3 Piece Cranks
« on: March 14, 2013, 06:22 PM »
I'm wondering / hoping someone has a tip for getting crank arms off.

So I have a couple of sets of Sugino GT cranks that i want to swap out, i've removed the end caps and bolts but the arms just don't want to budge...

Is it just a case of whacking them with a mallet or is there some sort of witchcraft that i'm unaware of?  ???

Try soaking them overnight in petrol or wd40

So the thread size for the crank arm / dust cap is universal across all cranks?

I have a crank removal spanner you can borrow if you want mate.

Let me know your address and I will send it to you.

Thanks for the kind offer Sean but I thought it was probably best to order one.  :daumenhoch:
