    The conversion process to an electronic governor would be interesting to see.
  • @frankbiz
    Love to see you convert it to an electronic governor and see that monster run. Great video. 👍🏻

    As a retired Onan Tech, it warms my heart to see a younger person who actually understands how generators work. There's a whole generation of 'technicians' who are parts changers with laptops.
  • @stevezwemer1262
    Interesting and obvious design flaw resulting in inadequate lubrication. It would be great to see if you can fab up an electronic governor and get it running. Thx for the video!
  • @marcdebow4055
    I would be interested in seeing the conversion. I am amazed at your knowledge of these systems.
  • @473mec
    I'd love to see you make the conversion to an electronic governor.
  • You are a great teacher in the way you devote so much effort into explaining theory, rather than simple diagnostics. I subscribed.
  • @Darryl603
    This set should be saved by any means possible! What a gem. Thank you for sharing Mike

    I've just discovered this channel. Sir, you have a gift for leading people through the topic, I really enjoyed your description; to do that unscripted, is a real talent
  • @thomasconci3930
    Absolutely get it operational, additionally what would the repair cost compare to replacement. Execellent detail.

    It's soo refreshing to watch a youtube channel that hasn't gotten a 'big head" like soo many others. This just seems like good entertaining and informative content, not a bunch of fluff and filler/ads. Thank you for a genuine channel.

    Cool video. I enjoy the failure analysis. It is an excellent way to learn. I think an electronic fix would be a great bookend for old school and new technologies.
  • @mcallahan9060
    Great video Mike. I'd love to see the conversion on that unit.
  • @jameslamb7300
    Awesome Video! You explained how a Governor works very well. Thanks for the tour.
  • Came to this channel for running generators. Stayed for the education. Bravo!
  • I think the governor's thrust bearing failed a long time ago, and the weights have been rubbing for a long time, increasing the governor drive load, wearing the gears excessively. I'm thinking the thrust bearing failed first, because nothing looks like it really got excruciatingly hot, which would be a sign of lack of oil. Nothing really looks very dry either. There are many engines that utilize "timed" oil supply for various things without issue. For example, the Toyota F-series engines only have one tiny hole drilled into the camshaft that supplies oil to the top-end once a revolution. I also believe the vacuum booster might also help reduce governor droop under load? It'd definitely be cool to see an electronic governor conversion. I've seen people do it with old aftermarket cruise-control modules before.
  • @AutomotiveZar
    Love the Vid man!.. I like how you analyze the problem before you start you work..
  • @chuckboyle8456
    Outstanding videography & fault diagnostics...excellent troubleshooting. Somewhere in an old Onan warehouse is a supply department shelf filled with 60 year old new governors waiting to be requisitioned. Sounds like a field trip to Onan in Part II.
