Me again with a new question – The water-pump has a threaded fitting that ties to the shaft to the generator. This is leaking- I loosened it and added some plumbers tape – I have determined it is leaking where the generator shaft is spinning. Can i buy a new gasket or make one – Thank you for all the help –
Asbestos packing in roll form compressed by the threaded fitting does the job. I’ve found modern seals to be unreliable even with a new shaft and reverted to packing. An occasional drip while running is not a problem given the huge capacity of the P-A cooling systems.
You can buy the water pump packing material at Restoration Supply Company.
They show the product on page 21.

While the above suggestions will provide good results, I have found that the boating folks have produced a far superior product for shaft sealing. A braided packing of high quality flax rovings impregnated with TEFLON is available (West Marine, for example) that seals with much less friction. The Western Pacific Trading Company PTFE FLAX shaft packing is to be installed with their SYNTEF packing lubricant. I have used this combination for over twenty years, with no problems — no leakage and no scored or galled shafts.
