I'm curious if it's possible to remove the belts from the steering pump and the AC without removing any of their respective bolts? We're talking a 1983 300SD.

I just completed changing the crankshaft seal and I believe I tightened the belts too tight. When I start the car, I hear a weird knocking noise that I believe is coming from the AC. I want to remove the bolts entirely to see if I can eliminate the source of the noise. I know I can loosen the belts without removing any of the mounting bolts, but worst case scenario, I'm looking for the easiest/quickest way to remove/attach the belts entirely.

On the power steering pump, there is the adjusting bolt on the top, to loosen the belt (after the 3 crossways bolts are loosened). However, it doesn't look like the pump slides far enough to remove the belt unless some of the cross bolts are removed. Or is there a way to remove the belt without removing any of the long bolts?

On the AC compressor, there are 3 bolts in the rear (top, left, bottom/right). The top bolt is stationary, where as the left bolt slides up/down and the bottom bolt slides left/right. I noticed there is a TINY adjusting nut on TOP, connected to the left most bolt, that takes a 10mm long shaft ratchet socket.

Unfortunately, the AC lines that route to the radiator are in the way of the adjusting nut, and the only way I can think of getting it out of the way is to disconnect the AC lines, which means removing the 15mm bolt at the bottom of the compressor as well as removing the 10mm bolt on the side (close to the chassis) that attaches the hard lines to a mounting bracket. There is very little clearance to do this, and it's a royal pain to get done.

I was wondering if there's a way to adjust/remove the AC belt without removing the large mounting bolts?

From what it seems like, it requires loosening all 3 mounting bolts, (and possibly removing the top stationary bolt as I'm not sure if the left bolt rotates or just moves down), detaching the hard lines from the rear as well as the mounting bracket, and then getting (via the top) to the adjusting nut for the compressor. There is enough exposed threading on the adjusting nut to lead me to believe it can slide all the way down to allow the belt to be removed.
