Isc 330 AC belt

So before I break something I figured I would ask you experienced folks. Trying to replace belts but can’t get any of the nuts to budge on ac compressor bracket, also noticed the ac compressor is resting on the bracket so even if I loosen the adjustment bolt I don’t see how the compressor can swing down to remove belt. Any advice on how to proceed?

P.s. How do I rotate photos? They are right side up on my phone but appear sideways on this post.
Thx

AC compressor swings up to loosen the belt. Loosen the lock-nut, and thread the adjuster in?

Looks like the pulley has some of the edge broken off.

Looks to me like it swings down. Loosen lock nut counter clockwise and turn the adjustment rod by turning counter clockwise looking at the end of the rod.

Hard to tell for sure. Perhaps the adjusting nut is tight as the pulley is tight. Start by cutting the belt off with a pair of loppers.

Yeah it wonít come down because the compressor is already resting on the bracket. Also photos are tilted left, top of engine is left side of photos.

Loosen the pivot bolts on right side of compressor, slightly. Next, loosen jam nut and the turn the adjusting bolt at the small hex on the end of it to make the adjusting bolt shorter. The compressor will pivot down to where you can take the belt off. Your coach has same setup as my coach.

Spray the threaded block next to jam nut, as there are threads in there. Also, if you can, spray the left end of bolt. It turns inside that sleeve on the end.

Hi Harry, thatís how I thought it would work but the right side of the compressor canít pivot down as it is already resting on the compressor bracket. Iím wondering if I have to take compressor out. I did wd 40 the threads and nut but it started bending the adjustment bolt so I stopped before I broke it.

Is there any way you can get you camera in there to take a picture? Iíll have to pull mine forward to take another look at mine. Maybe I can take some pictures, too. Give me time.

Yeah the second photo on my first post shows the compressor body (right side)already resting on the bracket. Anyone know how I can move the photos to right side up?
