Hi Oren,
Sorry for not updating the team on the unrelated pump leak; that's
a separate issue which has nothing directly to do with the motors.

That old pump leak was fixed with a US Seals seal, just as you had
correctly surmised. Guess which seal I bought?

Note: This is a classic "you don't get what you pay for" example:

Source by Pentair Part Number = $75 (x four pumps = $300)
Source by US Seals Part Number = $10 (x four pumps = $40)

That old leak isn't the problem here.

The new issue is that I am rebuilding the four old pumps that I
have lying around (& thinking about rebuilding the two well pumps
plus the one pressure pump in the pump house); so I have seven
~2 HP motors running most of the time (not counting the generator).

For rebuilding the seven motors, the key thing is to source the
right bearings. Size isn't enough. Quality also matters.

Hence this quest for figuring out how to source quality bearings
on the net for the pool and fountain pumps that I already took
apart.

Sourcing bearings is something only someone who has done it will
know as there are assumptions you're forced to makethat have nothing
to do with the actual trade number of 6203-2RS (such as quality).
