The answer to the problem when you build up the HP and ride hard the inner race on the stock inner primary which is pressed on the trans output shaft tends to walk, either outward and takeout the inner primary seal or walk in and take out the trans seal. Mine was the trans seal which makes it really difficult to then remove the old inner race as you can no longer get a puller behind it, with this I was back on the road the next day.
