Do I Need To Resurface The Back Of My Chuck

Second question when you take the jaws off of your three jaw chuck how do you get them on so that they all are equal you think you put them on at the same time and make sure they all grab at the same time but every time I've done it it's not equal what am I doing wrong I do see there is a one two and three on the jaws and I made sure that they're going into the correct slots

OK never mind I saw the second question with the jaws I lined them up with the grooves what a pain back to the first question to the gentleman that told me about razor blades thank you so so so much it worked now to my next task

You have three threaded holes in the back plate. Try screwing the bolts into those, I am assuming they are tapped through for jack screws. It should come right off. Work your way around them, and don't try to do it all with one bolt.

That's also sounds like a good idea but the razor blades work perfectly
I just wanted to give an update to everyone that was helping me decide if I needed to resurface my adapter plate and or my chuck. It turns out after I remeasured the proper way I found everything still off so I then started to take everything apart without knowing how to put it back together. UGH! One and a half hours later. I realized my only problem was that I was not seating the chuck properly to the lathe and once I seated it correctly my run out was minimum under 2 thousandth on the adapter plate and shy of 2.5 on the test bar. YEAH
