Slug the offending side with a nylon hammer, its how the bike shops do it.

That's not out of a 1991 XR250R is it?

[crazyxr250rider]

No, 2 stroke KTM 250SX. Selling the XR because I currently have 5 (running) bikes plus two bikes worth of parts ,piles of new 18 inch tyres (offWRFs)plus all my equipment and all my step dads other stuff cramed in there as well (horse float, 4 wheeler,list goes on..........)I can hardly move in the shed right now and need the space/money for a 05 RM250 that I might be buying soon, if I get the money in time that is...................:calm:

+1... seems a bit agricultural, but that's what they do

Just realized I dont have a nylon hamer just one of the tiny soft face ones......

Use a block of timber & a regular hammer then.

You probably haven't got a lead hammer either but they work well for this sort of thing.
(If you know anyone who works in an oil refinery or fuel installation they will have one of these hammers, as they don't spark when hitting steel)

Will It be ok if I just Hold one side of the crank by the web in a vice and just whack it or could that damadge the web.......

wrap a leather belt around the crank web and hit that with an ordinary engineers hammer.
