Take a half slice of bread and put in the hole before you put the puller in. Keep adding just a little bread if it still won’t pop off

 

Jack it up as much as you can on the driver side get some water in there use pipe tape on the puller to seal it she will come off! I've also done the bread method work great.

 

Impact isn't the right tool, just shocks the threads, you need steady pressure when pulling apart a taper. Breaker bar adding a cheater bar as needed.

 

That is what I was thinking. What’s the best way to hold the primary? I know they make a tool but don’t have the time to order one. Wasn’t sure if putting a wooden hammer handle or something between the towers would mess up the primary. Especially since the torque would be applied to one sheeve and not the other.

 

Not to long ago I had a buddy with a Turbo "S" call because he had been trying to remove his Primary for a couple of days. Told him about the fill the hole with grease trick and it popped right off. No problem using the grease as long as you do a good cleaning once your done. Have not tried the water or bread trick, but its more or less based on the same principle of hydraulics, so I would guess it would work.
