Compressor wheel stuck on shaft

[ziggo0]

Bought a used 14b in alright condition. Minimal shaft play, no in-out, turbine side is in great condition, compressor was chipped up. Picked up a compressor wheel in superb condition for cheap and I wanted to swap them...once I got the nut off and went to slide the old wheel off, it is very stuck. Any advice towards removing the compressor wheel without damaging the rest of the assembly?

Ive heard of carefully heating up the shaft and wheel then trying to spin it off with a rag, i had the same problem with my hx35, hope that helps you.

^I was about to try the torch but I couldn't find it. I tried this however, I put the nut on the end and put a piece of electrical tape over it and tapped it with my rubber mallet. I felt a 'pop' which I'm guessing was the sealing ring popping out and light taps afterwords got it loose enough for me to pull off. Upon inspecting the shaft/compressor, it seems like rust almost? Or oxidization? The shaft cleaned right up, turbo was rebuilt recently (within a year, it's a 14b afterall) and everything else seems in good shape!
