Perkins overheated

[Tamar]

My Perkins Genny overheated and stopped before I could get to it, a faulty jubilee clip on the heat exchanger was the culprit. Anyway after letting it cool down I replaced the clip and coolant and it started and runs ok. I ran it for an hour today and it seems fine, I also changed the oil to be on the safe side. Is there any lasting damage to this engine or was I lucky this time?

If it does not have one I would install some sort of overheat alarm / shutdown

I would also check the impeller.

+1, unless it stopped DUE TO an overheat alarm mine does have one, doesn't really have a temp sender and gauge, but a temp switch, if over a set value it dies protecting the engine.
Have a look around the thermostat housing for any sender.
Should also do the same on low oil pressure. Check the geny docs!

PS. I assume you don't have to go down there and pull any cable or whatnot to stop it and you can do it with a key or button

There is no sensor or auto stop on this Genny, to stop it I have to go down the engine room and pull the stop lever. Having said that, it ran for 12 hours today without a problem. I managed to get all new coolant pipes from 'parts for engines' the old pipes look original circa 1997.

well, an overheat alarm would be something I'd fit, but it would only work as a warning bulb or buzzer since you have to physically go down to stop it...
better than nothing!
but would be good to do the same for oil pressure.

I think ( but not sure ) onan have a pressure switch. No flow after x seconds of start and it triggers.

Making one would be simple. Pressure switches are cheap and it would just have a timer that enabled it say 10 secs post start.

You choice then is Either an alarm or shutting the gen down. If the Feb does not have a cut off you could fit a fuel line Solonoid.

Someone may well sell a kit to do it.

My gen has shut down several times due to cooling issues so In my view it’s worth sorting.

Apart from having a high temperature shut down is there anything other than seezing that would have stopped it?

I've no idea, but with no electronics/black box with relays and sensors I very much doubt

There is no electronics on this apart from the starting and chargeing systems. It's run a total of 36 hours since it siezed without issue, so I guess I was really lucky. It seems to start better since the seize, weirdly.
