IMHO, I would have cleaned up the outside and given them a nice new coat of enamel.

Chay, while these were apart, did you see any signs of thrust surface scaring, and were the impeller cams OK?

Correct me if I'm wrong here, but the oil seal was put in backwards, the lips of the oil seal were faceing out from that washer, on the tear down, and the flat side was facing up on install

look at 3:36 and compare to 15:12
It looks to me like he did it correctly...... but perhaps I'm not seeing it.
And by the way...... that is a water seal.
The other seals would be grease seals on the two sealed bearings themselves (total of 4 grease seals per pump).

might want to take a second look, there is definitely a grove facing up as he is tearing it down, then at 15:12 he shows the seal in his hand the grove is facing the camera, and then he flips it over and puts it on top of the washer, and as far as a water seal, its a rubber coated metal case seal, same as a oil oil seal rubber doesn't stay bent when you take it out with a screw driver, just didn't want him to get it put together just to do it over, not trying to be critical

OK..... I took a second look and I now see that you are correct..... this seal has been installed incorrectly.
A single lip seal (like this one) functions hydraulically in that when pressure is against the lip side (the side with the lip tension spring exposed), any pressure aids in the sealing ability. With this seal being reversed, pressure will actually cause the seal to allow water to escape past it.
The seal that was shown being installed needs to be turned around! [/color]
and as far as a water seal, its a rubber coated metal case seal, same as a oil oil seal

These are small and are likely all composite.... (no metal casing)
No offense to you...... I was simply pointing out eariler that these are not being used as oil seals. [/color]

FWIW and FYI
I'm all for re-furbishing parts when needed. However, these are sometimes on sale at a very good price.
Here is a new F6B-9 (large volume) for $140. New housing, new bearings, new shaft, new thrust surfaces, new cam, new impeller, etc.
