How to adjust air cooled diesel generator for perfect frequency

- I go through the process for setting an air cooled generator for 60Hz frequency using my AA Diesel Generator, rated to 5000 watts while using about 4500 watts as a load. This allows the pieces of electrical equipment to operate at there peak efficiency. Generators can drift in there speed over time so it is necessary to readjust sometimes. this process cane be applied for 50Hz if you live a different country.

Thank you, I had an over frequency error and shut down on a nearly identical machine. Its 50hz in EU. The previous owner replaced the "throttle" assembly and it makes sense to be tightened at a random spot.
Glad I could help you fix your machine.
its not the best video but the first one that dit make my understand how to do it. thank you for making this video.
really helpful.
no problem, glad it helped, why is it not the best video? anything I need to explain or clear up?
@@JoshKilen Forget this guy, the video was fine. People are weird. He states it's the first video that helped him actually understand this yet somehow it's still not good enough?
true.
Thank you
no problem.
What can cause over heat on this engine
overloading of the engine, blocked cooling air, both on the intake under the shroud or on the exit path of the cooling air, or missing cooling fins on the flywheel.
What temperature does the engine reach on the cylinder head during normal operation? Is mine reaching 120 degrees normal? What temperature does yours reach?
I can't really measure it since its buried in the generator housing. is that 120 degrees F or C?

Good vid I'll try this with mine once done is there any reason to adjust the avr to iits a 16 hp 10kva open frame diesel generator seames to be lagging at about 6500 load
glad it helped.
Any reason to adjust the avr on it ?
to get perfect voltage. I should of put a disclaimer in it for people with 50Hz machines.
i think your question have not much to do with this video, AVR is for voltage and this video is about speed or Hz.
No there is no need to do that, only when the voltage is a little outside the range you can consider adjusting your AVR, but can be a different defect as wel you need to check that furst. @@alanshiels4868
Hi, so what is more important, voltage or hertz? I have a 1300 watt geny and I set the voltage while under 750 watt load to 120 volts. Is that good enough or should I really get a Hz tester? Is it even possible for the Volts and Hz to be that far from one another? Cheers!
it really depends, but Hz would be more important for loads. the reason why I say that is motors and electronics are designed to work at 60hz or as close to it. if they get to high or low of Hz it can cause motors to not run at there correct rpms, plus overheat and for electronic loads it can cause them to be come grumpy. my generator has it voltage controlled by a capacitor, so the voltage is set to what it is with rpms. in that case set the Hz, and the voltage will be good enough. If the voltage is not within 110-120v then the capacitor needs to be changed. but some generators come with whats called an AVR or automatic voltage regulator, which does a much better job getting the voltage where it needs to be. with those set the Hz and if the voltage is not within 110-120 then you can adjust the AVR to make it right. As for getting a Hz reading, you can buy the P3 international "Kill-A-Watt" meter and it will be just fine. May I ask what are you running that is 750 watts and what type of generator?
@@JoshKilen Hey thanks for the reply! It's just a back up generator that I paid 60$ for. (United Power GG1300). It had a blown capacitor which I recently replaced. But it seemed like the previous owner had messed around with the idle and governor before giving up on it so they needed to be reset. I went 120v at idle then 120v under load and was using a space heater on low setting.
ok, got love other people's problems, lol. nice job sorting it out. do you plan on just using that space heater when you use it or electronic loads like tv's or laptops?
@@JoshKilen I plan on trying to sell it to a neighbor so they can power their furnace in the event of a winter outage. Not looking to make a profit just recover costs. But I want to make sure I'm not handing off something that could damage whatever they choose to run with it either. I've already got two invertor generators but if it doesn't sell (for 70$) then I'll keep it as a back up and also be sad that my neighbors are dumb. lol
it wouldn't hurt to check the Hz.
these chinese generators are very sensitive.not to exceed 60% of its power.
I sorry to say but a diesel generator needs to run between 60% and 75% of its rated load to run most efficiently and prevent wetstacking.
