h4nd Posted February 19, 2023 Share Posted February 19, 2023 Some motors have 600-800% start current. It all depends a bit on various overload characteristics. A little VSD after the genny would probably help tune the load to the supply, reduce the startup current to ~250% Quote Link to comment Share on other sites More sharing options...
Nominal Posted February 19, 2023 Share Posted February 19, 2023 Yeah, it's always starting against load / water pressure. I reckon a 5kw should be ok.. . Quote Link to comment Share on other sites More sharing options...
fletch Posted February 19, 2023 Share Posted February 19, 2023 Luck of the draw I would say. Some 2kw generators would do it. It depends how good the generator protection is. You could try it on 2x 30m leads joined together. It will lessen the voltage drop at the generator, but not really practical as a long term solution. Single phase can be a bit of a prick. 1 Quote Link to comment Share on other sites More sharing options...

h4nd Posted February 19, 2023 Share Posted February 19, 2023 Downside is that it's better to run a small genny under load? Big ones coke up at long runs on low load? (I've heard, 2nd hand) Quote Link to comment Share on other sites More sharing options...

(I've heard, 2nd hand) Well, there's more that could be plugged in. The water pump can just be run once in a while to fill the header tanks in the house. We only have tank water, and while there is usually plenty in the tanks, getting it into the house needs the pump. That way the wetback would heat the water if needed too. Cheap option, J5 spec without the fancy changeover wiring. https://www.trademe.co.nz/a/marketplace/business-farming-industry/industrial/generators/diesel/listing/3998497842 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted February 19, 2023 Share Posted February 19, 2023 Not sure what the situation is, but could you "tee in" a petrol water pump? Might be cheaper, might also be useless for your situation. 1 Quote Link to comment Share on other sites More sharing options...

Yes they do coke up if they are not loaded. Can take a while to happen but does happen. Example was a camp generator. Nice 4cyl perkins turbo. Ran for a couple of years 50% of the time it had no load really. Ate itself and nearly ran away. Was a bit exciting. Mechanic pulled it apart to have a look and it was curtains. Then he left and the container door got shut.... Starter motor and alternator fitted my tractor tho 3 1 Quote Link to comment Share on other sites More sharing options...
Nominal Posted February 20, 2023 Share Posted February 20, 2023 Picked this up yesterday, probably won't have much generator protection. No idea if it goes though. 4 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted February 25, 2023 Share Posted February 25, 2023 What do people do with engines that will sit for a while. I'll have a mostly stripped engine that I plan to leave in the shed. Do you add more cheap oil? Oil in the cylinders? Blow out all the coolant lines? I could google, but you lot will have engines under your benches, so what do you do with them. 1 Quote Link to comment Share on other sites More sharing options...
HighLUX Posted February 25, 2023 Share Posted February 25, 2023 Keep it full of the oil already in it so its a nice oilyboi. Plugs out and a squirt of oil down each cylinder then turn over a few times by hand then put plugs back in, remove plugs once every 6 months or so and repeat 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted February 25, 2023 Share Posted February 25, 2023 Cheers, sounds like a plan. Something to use up the part bottles of oil with. 1 Quote Link to comment Share on other sites More sharing options...
tortron Posted February 25, 2023 Share Posted February 25, 2023 Morrie I drained the coolant, ran the carb dry, filled all the cylinders with moreys and parked for 2 years. Started right up, little. Smokey for the first 100m 1 1 Quote Link to comment Share on other sites More sharing options...
datlow Posted February 26, 2023 Share Posted February 26, 2023 Wd40 on the alloy maybe? My 2 motors that have been sitting for 30yrs don't seem to have enjoyed the alloy corroding on the coolant outlet... But they may have been chooched 30yrs ago?? 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted February 26, 2023 Share Posted February 26, 2023 Will see what I have to coat it with, good idea. Was going to put it in shed, but zinc change and hook on my engine crane are starting to corrode... so I think the shed is a bad idea.

ajg193 Posted February 26, 2023 Share Posted February 26, 2023 Are all die grinders crazy air hungry? I got a Ryobi one and it is rated for something like 4 cfm at 90psi. My compressor, tested at 9.3cfm at 90psi, can't keep up with the bastard at all 2 Quote Link to comment Share on other sites More sharing options...

datlow Posted February 26, 2023 Share Posted February 26, 2023 From previous exp yes Also have an electric one, don't see how they can be so much more energy efficient but also alot bigger and heavier Quote Link to comment Share on other sites More sharing options...
