SBC Son of Strongarm

Hello everyone, I'm loving this site - I can't stay off it!

I am trying to remove the son of strongarm crankset from my 1997 Specialized Rockhopper. I have a crank puller which I have used to remove the Deore cranks from my 1988 Giant Escaper, but the bit which threads into the crank seems too big for the Specialized crank. Does anyone know if it needs a different size puller than the Shimano one?
 
Re:

Just removed a pair of these to sell and they are normal threads as per all other chainsets
 
Shouldn't be anything special. Any branded or non branded puller you can get nowadays should do the job. Had no issues on my Rockhopper. Would be more inclined to think your pre-90's bike might have been threaded differently? But I'd doubt that.

Ah ok thanks for your replies, I am maybe not being patient enough. I'm off to give it another go.

Are you sure the crank isn't stripped? Or maybe there's damage to your pullers threads?
 
Re:

Likely the crank threads are ropey.Its important to make sure that the extractor thread is going in perfectly and is square.If its fractionally off you will strip the threads.
 
On closer inspection the threads look to be deformed, I managed to get it off by tapping back and forth with a mallet.

They sold whilst I was sleeping. Can’t beat that. Was it to you?
