Question What puller to use to remove March underdrive pulleys?

I've searched and came seem to find any info. Swapping out my opti and I need to remove the crank pulley. I have removed the stock dampener that was sandwiched to the UD pulley, but am unable to get the UD pulley off. A threaded puller won't work as it just threads into the hub and the March pulley has no threads. I don't think a claw type would work as it will bend the pulley. Anyone know?

Nevermind, got it. :)

I used the jaw puller and it worked just fine.

I think the March pulley just "sandwiches" between the stock damper and the hub. Have you tried a liberal application of PB Blaster, and letting it sit overnight. The stock hub rusts like crazy.

That's correct Fred. I was originally able to get the stock dampener off by hand. That left the March pulley still pressed on to the snout. I was able to use a 3-claw puller to remove it.
