Folks,

On my 87 SDL I was replacing the A/C compressor a month ago. The new compressor pulley was slightly larger than the one in the car. I tried to strech on the old belt... no luck. Not fully understanding the adjustment process for the belt tensioner, I bought a slightly longer belt.

I was able to remove the old belt and insert the new belt by taking them off all the pulleys then very carefully routing it around between the fan and shroud. Then the normal belt on pulley install and alignment. To reach the last pulley it required moving the tensioner via a large screw driver in the tensioner pry hole.
