I was trying to remove the AC pulley from the 97 Maxima, hoping to replace the pulley bearing.
I removed the bolt holding the clutch plate and the clutch plate itself.
Then I removed the first 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:
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.
After about 20 minutes, I got my head together and I reinstalled the seal and the snap ring, then installed the clutch plate back so that seal part stays clean.
Please see photo for compressor model.
I unplugged the compressor electrical connector and installed a 36" serpentine belt to bypass the A/C. I have been driving the car like this for 2 days.
I do want to fix the A/C though. Any pointers?
The bearing seems to be a NSK 928 40bd219duk.
