Belt alignment appears to be off on the A/C compressor ‘90 GT. All washers on the crank pulley are on correct. When running there is a noticeable wobble in the belt. Is the belt pulley on the crank bent? What I can tell the compressor could be moved to the front farther but there is no way to adjust. Any thoughts?

How's the mount to the block, cracked or re-welded?

It looks to be in good shape. I loosened some of the mounting bolts and wiggled it around a little. Nothing came apart in my face or was broken. Is tight.

Bump?

how about a picture of the other end of the belt where it goes around the crank.
Has the compressor ever been changed
what was the last thing that you fixed before you noticed the misalignment

The misalignment has been there since I got it 2 years ago. Always noticed black powdery residue on the oil pan. So it’s a pre-existing condition. Not terribly eating the belt but it’s not normal. I have 2 videos but doesn’t want to upload to Rennlist.

Any my suggestions to upload video?

2 videos. Of course the belt closest to the engine block.

It looks like someone used a pry bar to remove the AC pulley from the crank shaft and that is causing the wobble you see. It could be causing the tracking issue. Most times I've seen that mis-alignment is due to the mounting bracket/block points and have had to replace a few of the mounts. Next time you are in there for a TB job I'd replace the pulley.

I think the place to start may be the Pulley. Not a major concern, but I may order a new pulley. Thanks everyone.
