Having trouble finding ANY help on the internet concerning this type of ac clutch found on my Blazer.. I guess there are a few different types of clutches found on these late s10's. My compressor has NO bolt holding the clutch in place.. How does it separate??

It seems there is a clip around the shaft, but I am uncertain how to remove it or if it needs to be removed..

Thanks

 

What brand of compressor is it? Can you find any help by chasing down the compressor online?
