Need help on belt replacment!!!
 

I have a 1981 300d and I need to replace the alternator, water pump belt. I have already just cut the old belt off because I put in the larger AL129x alternator because of the stereo that i have, and needed to take it back out which lead to me cutting the belt because it was so tight. All I need to know is how to loosen the belt on the power steering pump. and how to re-tighten it after putting it back together. I have seen it done before but it was about 2 years ago and forgot. I went ahead and bought a larger belt 41.5 inches hopefully this will do the trick. Pictures would be greatly appreciated.

The power steering pump has three bolts on it. loosen them and then adjust the tension with the nut that protrudes from the bracket. Here are some pics to help...

*I usually forget one of the bolts...

I have also put in an AL129X but I did not need a longer belt. You just have to play with it until it fits in the same space as the old alternator. If you loosen all three alternator belts and back out the tensioning bolt all the way, you can get the normal belts on it.
