just changed out the water pump in my e320. added water to the radiator....started it up.... water pump pullley wasn't turning..

shut engine off...loosened the belt...

When i turn the pully it turns about 180 degrees and hits a spot where it won't turn, unless i really try..

in other words, it won't turn freely 360 degrees or a full circle.

What did I do wrong... I have done several of these and this one is killing me....
