That's really rusty??? Yes it just slides off after bolt removal. I use oil filter pliers to hold while loosening.
I just went to salvage yard this week and pulled 4 of them off.
There are several common ones, shared among many manufacturers of vehicles.
I was getting the 3 round rubber vibration thingy ones but other style like the one you show fit too.
I found that there are two different common spline sizes. One ever so slightly smaller.
The 8mm bolt is the smaller splined shaft and the 10mm is the larger. Too easy..right?
Some were stuck pretty good. You can spray penetrating oil in center hole but I don't think it helps. I used two screwdrivers and worked them off. Of course I prefer the ones that slide off. You can bend it too much and create a problem, but getting old off it doesn't matter as you are tossing that one.
Hopefully you will be ok with new but often the compressor is locking up or giving to much resistance and that is what makes the clutch slip and smokes it.
I don't think you can buy just the front piece without the whole clutch (magnet coil and all) and they are pricey just to test and maybe burn it up too. Been there, done that.
I was replacing one on an aftermarket comp but it fits volvo semis. The EXACT clutch front was on many Nissans. I think I pulled one off a Murano.
Super cheap at self-pull lots.
