Jimmy -
Its a shame that you had all that trouble with the pumps. The 3-port pump is useful only in machines made from 1976 forward, which have either a waterfall manual filter or a non-recirculating filter under the basket (late production models after 1982 or so).
The three port with the boxy chamber as shown on the left in your picture is not capable of recirculating water directionally through the pump as the old 2-port is. Water flows through the inlet in only one direction and the recirculation is accomblished from the tiny third port, whereas in the two port water flow reverses direction based on the position of the shift lever and is always flowing in one side and out the other. All the shift lever does in the three port is open or close the back port for draining.
The three port you show pumps massive amounts of water per time as compared to the older pumps. Whoever advised you to use it on your beautiful machine was mistaken - that pump design wasn't "born" until your machine was 17 years old.
If in the future you have any issues with NOS pumps leaking, I have had some success with putting hot water through them - a load or two to make the parts warm up and expand has usually made a new pump seal itself again.
What fantastic shape the outer tub is in. That is GREAT. I think your decision not to pull it was smart - those rusty centerposts can often cause the tub lip to crack when pulling the tub, then it is much harder to seal.
I hope you enjoy the machine for many years. Great job!
