Just an update. I replaced bearing #21 in the below referenced diagram. To get the new one in easily, I heated up the clutch housing and had previously put the bearing in the freezer. It dropped into place. No hammering or pressing. I quickly cooled the housing off, not to damage the bearing. I heated it to about 300 degrees with a torch. I used a laser temp gauge to ensure it was hot but not too hot. After I cooled it off the bearing would not come out by hand.

Nice job!
