[Vwdiesel] crazy cam gear removal

[Bart Wineland]

Thanks Sandy. I didn't describe my technique very clearly but I am doing it 
just as you suggest. Grabbing through the gear holes with the arms pointing 
into the center of the hub. I have rapped the head of the sprocket bolt 
harder than I know I should, or want to and I did not want to have to heat 
the gear but have done both, still with no success.  I center punched and 
drilled the center of the gear bolt to keep my puller stud from wandering 
off the bolt head and falling off, so I am getting good pressure now on the 
gear and that bugger still won't come off.  I tore my old junk engine apart 
a month or so ago just to practice and had no trouble getting that gear 
off? I'll keep trying and thanks for your response.
