<VV> removing yokes from EM drive shafts

[Yelospdr64 at aol.com]

Someone told this would give me fits but I didn't think it would be this 
hard.
I have tried several different tools to no avail. Right now I have a gear 
puller on the yoke, with two bolts through the holes where the U bolts go, and 
have tried torquing the center bolt with an impact wrench and a breaker bar. The 
thing won't budge. I though about building a puller out of old yokes as 
described in the tech guide but I don't see how this would work better than what 
I'm using. Is heat the only answer. One friend suggested splitting the yoke as a 
last resort. Should I, could, I use a cut off wheel to do this? 
Thanks in advance
