24V generator out

24V GeneratorSo that's my troublesome 24V generator, which runs off the main engine, out.

I would have taken a picture of the actual generator, but forgot. So all you see is where it came out of.

The reason for taking it out is that the bearings have gone, so when I last ran the engine it was making a huge noise, and was running hot.

As it turns out, the company I would have taken it to for refurbishment seems to no loner exist, so now I guess I'll have to make another plan.

  1. Is it just the bearings that have gone? if so take out the old ones out,take off the numbers ( susally on the side) and buy new or maybe use the local car
    repair shop to do it for you. "Dowding and Mills" springs to mind thats where I used to have all my motors and alternators repaired (sometimes over night "expensive) Hope Im not teaching you to suck eggs? sorry if I am :o((

  2. Hmm - the local car repair shop is certainly a good idea.

    I'm thinking they might have the right tools to extract the bearings from the casing.

    Thanks for that.

    Cheers

  3. Usually you can undo the long screws on the alternator (that hold the two end caps togeather) take the end caps off and press the bearings outfrom the insie using the appropriate sized socket a couple of blocks of wood and a gentle tap with a hammer or two sockets a large one on the outside (bigger than the bearing, a smaller one on the inside (THE SAME SIZE AS THE BEARING) and a long bolt through the two with a couple of washers on each end, tighten the bolt and the bearing is drawn out of its housing ? Possibly, I guess youll get my sockets explanation? it all depends if you are able to the end caps off

    If fixing the old generator causes much hassle, I might suggest replacing it with a modern 24-volt alternator. You should be able to get a serviceable used/rebuilt 24 volt alternator designed for a diesel lorry and fab up the necessary bracketry for it.

    FWIW, I think in your photo from Friday, February 09, 2007 there is a think visible at Robin's knee, which I take to be the now gone generator.

  6. Hi Rob

    Thanks for that.

    I suspect the main issue is going to be those very old, seized bolts which hold the thing together.

    I'll give it a go next, as my local car repair shop don't want to know.

    Cheers

  7. Hi Anonymous (1)

    In a way I'm secretly hoping the 24V generator is destined for ballast, as it would give me the opportunity to install a 24V alternator instead.

    With the boat's current setup, 240V is much more practical for me than 24V - I can always run the 24V charger from 240V.

    Regards

    Tim

    Wow - sometimes the comments and observations of my readers completely amaze me!

    We knew the generator bearings were iffy at that stage, but opted to replace it, so everything was all up and running for the journey round.

    Thanks for that.

    Or alternatively grind the nuts off the long bolts with an angle-grinder and tap them out or drill the heads off and replace the whole bolt!with say threaded rod of the same size
