My VT cam was supplied without a gear. I wanted to reuse mine anyway, the motor was so quiet and smooth (for a Harley) that I didn't want to change anything unless I had to.

IMO putting a camshaft in liquid nitrogen is a really bad idea...you just performed cryogenic hardening...not a good idea on a camshaft...the cheapest press made would install it in 30 seconds.

They cryogenically treat camshafts, as well as other internal engine parts, to increase strength and wear resistance.

Yeah but not something you could do on your kitchen table...lol. Place where I worked send out mill parts to be treated all the time...that's why I know about it. Not just any steel would work...we had to get it from Germany. What you did will be fine...didn't know you didn't directly expose it.
