1981 240D with A/C. This is the type of A/C compressor that is below the powersteering pump.

I've been trying to get the belt onto the pulleys, but I can't get the A/C compressor to move to the end of its adjustment. I loosened three main bolts, and loosened the adjuster.

I can pry the compressor over about 1/4 inch but there is still atleast a 1/2in of travel left. Am I missing something? It seems as though the A/C lines could be holding it back.
