Hi

the proper 52mm box spanner won't shift it, and neither will a chisel and heavy hammer blows.

Have drowned it in penetrating fluid.

Am I OK to apply heat?

Cheers
 
My dad has made a 52mm socket and braised a handle on to it, works a treat, if there is any rubber near it I wouldn't apply heat IMO
 
Weirdly enough i've had the same problem. Not fixed it yet, as I want to get replacement nuts before I destroy it, but my plan is to drill a few holes in it, until i've gone all the way through and then it should come off (or at least unscrew fairly easily...)
 
Be careful when slitting the nut against the lock tab flat, although there is no threads to get damaged at that point, the axle tube is quite thin and you can deform it, crushing it inwards, the drill method is best if it is really badly stuck, ive had to drill the odd one off in the past, as well as the outer bearing race in the case of a RMC 110! but the big 52mm impact socket and breaker bar or impact gun usually works best for me, :)

have you actually split a nut , there isnt a risk of crushing stub axle
