Ca: A/c question

So i took my car back to an a/c place and they said again my compresors cracked but i dunno. It looks strange to me. It definitly has no belt. but there are 2 wires that look like they’ve been pulled into the wheel. and there are extra wheels also on my compressor. does anyone have a pic of a/c compressor installed so i can see what this thing is supposed to look like in my car. I think im bein lied to.
