Good afternoon.

Yes, you can but you will see a big reduction in engine performance.

What is the issue with the unit?

Do you mean on the drive belt on the engine or the pulley on the supercharger?

Any hints for me to help access it? It looks like I will have to remove water pump to access the bolt.

If it is in the supercharger, you will have to remove it to disassemble it.

Anything in this picture?

You will need to drop the power steering pump. There are two 13mm bolts holding the pump to the block. You can access them through the holes in the pulley.
