Can the flywheel flange be removed from the crankshaft itself using a harmonic balancer puller tool, and if yes then wats the process to install the flywheel flange back.

In one of your links, I see that you have the flange #6434 by itself.

Yes, that is a newer crankshaft with a one-piece main seal, yours has a two-piece rear main seal like the one in this video.

It is a one-piece rear main seal even if it is a newer crankshaft how are you to replace the seal?

I see what you are talking about, I have never used one of these, so I was a little shocked. It looks like a spacer for what I do not know. Check out the images (below). Please let us know what happens.
