These are the photos of the problem. I have replace the rubber metal reinforced linkage between my generator and water pump. The shaft itself is not completely straight. This is the result after running in for a about 10min. Any sugguestions?

    Not clear what problem is - could I machine a new shaft for you - possibly stainless steel ? Gert (retired machinist in SLC, UT. - do you have dimensions? If this is possible I will give you my email address.)

    It needs to made in the style of a rag joint.

    The problem is the tearing of the reinforce rubber connector. One person said maybe the generator is shot and needs too much power to rotate? I will check on that. I did notice that there is a slight offset to the generator and the shaft that may be the issue. Making a new metal shaft does not seem to be the solution or the problem. However, the shaft is worn but on this 1923 Hudson we would have to remove the radiator, oil pump and water pump to add a new shaft. I think I will let the next caretaker of this car do that.

    Sounds good Robert - if I can help let me know. Gert

    The gen can be shimmed in its cradle.

    The mounting plate needs adjusting to align the two shafts. The three bolts are a loose fit in the holes, allowing the plate to move sideways, and the threaded plugs can be screwed up or down as necessary to align the generator and water pump shaft.

    Thanks Geoff,

    You always have the answer. I did notice the shafts were not lined up when I replaced the flexible joint.

    I need to do a better job of lining everything up!

    Does anyone know where I can find the steel reinforced tube that connects the generator to the water pump shaft! Was this a special part or will any reinforced tubing work?

    I have never seen steel re-inforced. The usual ones I have come across have a canvas type re-inforcement layer, similar to insertion rubber.

    Like Jeff says - could radiator hose work? Gert

    McMaster Carr sells steel wire reinforced rubber hose.

    What about using a shaft coupler?

    A shaft coupler would be too inflexible. Heavy duty re-inforced rubber hose is the best. Steel re-inforced maybe too stiff as well, best stick to the original.
