I was trying to remove the AC pulley:
I removed the bolt holding the clutch plate, the clutch plate itself; there was no shim.
Then I removed the snap ring.
Then I made a boo-boo and removed another snap ring and then a vapor and yellow oil blew in my in face. I jumped out of the way, scraping my elbow and leg on the pavement and rushed into the bathroom to wash my self and my eyes.
I return to the car, the spraying had stopped by now and I see the results, please see the photos.
It looks like I depressurized the AC by removing some kind of seal. I have to stop doing all but the most simple tasks while it's hot, I can't think straight or concentrate in such discomfort.

Please help me fix this!
Mean while, if I put the seal back in place, and bypass the AC, will I damage the AC system if driving the car?

 

Some members install a shorter belt. It bypasses the ac. Then you could drive as usual.

 

I forgot to add the car is a 97. Please see photo for compressor model.
I reinstalled the seal and snap ring, then installed the clutch plate back so that seal part stays clean, unplugged the compressor electrical connector and installed a 36" serpentine belt to bypass the A/C. This way I drove to work today.
I do want to fix the A/C though. Any pointers?
The bearing seems to be a NSK 928 40bd219duk.
