Yes of course, if you're cooling one part seperately. But you're 
going to have to remove a lot of energy to shift that thermal mass 
after heating it. Not worth the hassle for parts this large although 
I've certainly used the method for precision bearings and such. My 
point was that heating will result in a larger space between the 
parts than when cold. I have a ready supply of LN2 so I can cheat, 
using a can of component freeze seems like pissin in the wind. Just 
heat it red and wind it out.
