I tried to gut mine but when I put it back together it would not turn if I tightened everything down snugg. If I left the screws/bolts backed off it would wobble. And mine looked like yours when I cracked her open so I was pretty sure it was dead in the water. JimC pulley has been flawless though.
I can't really advise you any better than others on whether to rebuild or roll the dice with an off-brand unit, but... replacing it without pulling everything apart is definitely do-able, just tedious. I loosened my PS pump enough to push it out of the way and was able to get the old smog pump out and a NAPA/Cardone unit in. Lots of wiggling, and turning, and twisting, and cursing. There's not a lot to unbolting the pump - all the pain is in the logistics of getting it out, and then reattaching the inlet and outlet hoses.
Having a copy of the emissions manual/diagram handy is helpful if you decide to disconnect anything along the way to improve access. But like I said, only thing I moved was the PS pump and that was just a few inches over.
Good luck - and remember that replacements don't usually come with a pulley, so save yours.

Beno, do you find that air- cooling your valve springs gives an appreciable horsepower gain?

Absolutely, especially with the ZDDP Zinc additive. At least a 24hp gain at WOT.
if mine were organized it would look almost as good-i need me some shelving, wife would then know how much i have invested in parts
