Here goes, I have been meaning to do this for a while now sorry it took so long guys.
After a long exhausting rebuild of my 79 wr something was just not right. So I started investigating and I found that some clown put a different crank and rod in my motor and put it back together with the original crank seals . The crank (clutch side) had a smaller diameter and I never caught on to it when I rebuilt it before . Well , major leak because my crank is 28mm and my seal was a 30mm so split the cases again and put in a 28mm seal and put back together and then it would not start. Found out the motor had no compression because of a rod that was to short and it had a tight crank seal , so no start any more that it was all sealed up. Split cases again and have some pics for you all to ride thru.

Here is the old crank on the left and the correct crank on the right.

Here is the new seal that I finally got to install. Thank you for the info on the viton seals Darty.

Case split again...

found a perfect fit with this socket too. 1 and 1/2 in. taps it in real nice.
