Question Cover on A/C Compressor Clutch?

Hello MBWorld Members,

I recently decided to replace my A/C Compressor so I ordered a new one and it came with this metal cover over the clutch, should I leave it on or take it off (if I should take it off, how do I take it off, it seems very solid)?

How the one in my car currently looks (and how it looked in the picture where I bought it from): https://imgur.com/a/SALcbvb
How the one I ordered looks: https://imgur.com/a/MJGRH5O

Thanks for your time MBWorld

This is how the one that shipped to me looks, with a cover over the clutch.

This is how the one in my car looks and how the one I ordered looked like online.

Photo of the label, model information?

It seems you remove the center bolt and it comes out as a single part.

yeah but I see the paint marking on the bolt and cover thingy which means it was a QC check the bolt was installed and torqued properly.

No, I ordered one from ebay, it arrived and looked very similar to the one that was OE.

I ended up installing it and charging the system. Works well, AC blows nice and cold.

For anyone wondering, I torqued the mounting bolts to 18 foot pounds (I just eyeballed one because it was hard to reach) and I just snugged up the connectors for the low and high sides.

I'll be checking up on it in the coming days and weeks to make sure its all still study n whatnot.
