I tried to put this back together but it wouldn't fit. The new seal had a larger O.D. than original. First I thought I ordered the wrong part, but after some research this wasn't the case. I ordered the parts from Ronnie at http://http://www.tractorsmart.com/enter.htm so I gave him a call. He remembered a service bulletin about this install so he emailed me this.
