If I loosen the four bolts that hold the pulley on the shaft would the entire pulley and clutch come off as one or does the screw in front of the clutch thread into the same piece that the pulley is attached to?

Note: This job is becoming bigger. I have been noticing a very small coolant leak that only seems to occur after the engine is shut off. While dismantling for the tensioner I noticed that the water pump shaft has a wet stop. Looks like I found my leak; at leas I hope so. Going to have quite a parts list when it is done, but with this tear down for the tensioner it would probably be a good time to take care of the water pump. This car is quickly trying to make up for all of my years of low maintenance cost W123 driving. I would be able to get rid of this car now. I will have too much money in it. But at least it isn't like my 1999 Jetta TDI that at 120K miles had a turbo failure that tossed a vane piece into the intake and take out a valve. Looking at BIG money on that POS.
