[C320-list] Seawater Cooling Pump Johnson Part Numbers and some Yanmar Numbers

[Albrecht, Alan]

1.	Impeller = Johnson Number 09810B or Yanmar 128990-42200
2.	O-Ring = Included with Johnson Impeller kit above or Yanmar X0506523-01 (The O ring was out of stock but any automotive right size O ring should work)
3.	Cam Johnson 01-452888
4.	Cam screw Johnson 01-46794-03
5.	Shaft  Johnson 01-45313
6.	Bearing Johnson 01-45207-3 (This is actually a bushing similar to what you have on an automotive water pump. You will need a universal bearing press to change this out.)
7.	Yanmar cooling water pipe 128690-49010 (This is the formed hose between pump outlet and the heat exchanger you might as well change it while you are at it)
8.	Glycerin, Vaseline or lube to lubricate the inside of the pump until it refills with water. You may want to consider installing an automotive radiator flush and fill kit on the pump inlet hose to help prime the pump at start up.

Items 3 and 4 are optional for a pump rebuild if the originals are at all usable. If you have other problems e-mail Johnson Pump directly they were very responsive and helpful.

Other useful numbers:

9. End Cover Johnson 01-42388-2
10. End Cover Screws 0.0141.500
11. Replacement F4B-903 Pump Johnson Number 10-24165-2 (it is around $400 USD)
