Stupid question what is this called
 

What is the thing that is holding the pulley called is it for the ac?

AC compressor clutch

The clutch doesn't actually hold the pulley on, but I'm guessing that's what you were trying to find the name for...the thing in front of the pulley.

What did you do roll your Heep? The pic looks like it.

Just turn pc to right 90 degrees it straightens right up...lol...

Priceless :lol:

Where's the fan shroud?

Turn the pic and shake it, probably just fell down somewhere.

:stuart: That's good.

I'm guessing he is wondering why the center plate is not spinning too.
That center plate with the 3 big rivet heads is the face of the compressor clutch. If the compressor was actually running the clutch would be engaged and the plate would be spinning with the pulley.
I agree, where is the fan shroud??? It is not there just for protection, the shroud helps the fan pull more air thru the radiator. You'll be more likely to overheat without it.
