Thanks for watching! The kit did include a new shaft seal, but after looking at the condition of the one in the pump housing, I opted to keep the one I got as a backup. To maybe answer your question, its a metal bearing which has a rubber seal grafted to it with a small circular spring that seats around the inside opening to ensure the rubber doesn't contract differently from the shape of the shaft and leak prematurely.
At the time of this upload,
Merry Christmas and Happy Holidays from my family to yours!
Is the front seal a O-ring? cool video,
