Thumbs up Re: Generator Questions and Answers, by R&J Control Inc

Excellant idea-- I'm sure many racers have questions regarding "situations" with their Onan as well as maybe troubleshooting other makes as well.
Those situations might range from how to winterize a generator to heavy repairs like replacing engines or rotors/armatures etc., routine maintainence questions and the like...

Matt: Since you are probley enjoying the nice weather at Maple Grove I have a quick question to break up all the excitement. Recently bought a very clean used Vintage trailer with a Honda EV6010 gen-set. (600 hours) Seems to have be well maintained and runs perfect. Question is; seems when I check reviews people either love them or hate them?? What do you think? We run our gens alot and always had excellent luck with our previous old green onan. Should I consider something else. We have a normal LQ trailer with 2 13500 roof air's The Negitive reviews seem always be reliablity and cost issues in the generator repair or the engine cooling system repairs. Thanks Bill

Thanks for your question.

We don't have a tremendous amount of experience with the Honda rv units. I've worked on a few and like all hondas, the quality is exceptional. This unit is liquid cooled and runs at 3600 rpm. It's a twin cylinder so I would expect this unit to have a 4,000 plus hour life expectancy before major work is required. Like all machinery, preventive maintenance is so important to it's lifespan.

If you have doubts about the machines ability to serve your needs I would recommend you carry a small spare generator. Something big enough to keep your batteries charged and lights on, say 2000 watts.

If you'd like to talk more about your generator options email me at matts@rjcontrol.com

Question Re: Generator Questions and Answers, by R&J Control Inc

Matt, I have an Onan/Cummins Quiet 4000 generator in my MH. What is the realistic oil change interval (no oil filter) and is synthetic oil OK? Thanks in advance. Jim

Thanks for your question Jim!

I get many questions about oil change intervals and also the type of oil recommended.

On your particular model, the MicroQuiet 4000, the factory says, change the oil at 150 hours, more or less depending on the conditions of use.
Hot ambient conditions and heavy loads, all will require more frequent changes. An RV that is not used much, would only see maybe 30 hours per year, so the factory says, change it annually in that case.

Realistically, in my opinion, 100 hours is a good interval mark. After all, that unit runs at 3600 RPM, is a single cylinder machine, and if we made a comparison between this machine's 100 hours of operation and mileage, we would probably arrive around 4000 miles. So, given that it's just one and a half quarts, I say....do it, do it frequently....

On the subject of what type of oil to use, the factory recommends 15-40 weight oil between 10 and 100 degrees of ambient temperature. In my opinion, Shell Rotella T 15/40 is an excellent choice, reasonably priced and will provide heavy duty protection. That being said, all synthetic oils of good quality names I'm sure will provide excellent protection however I will caution you to observe the weight ratings and don't use anything light such as 5/30 unless you are operating the machine in frigid conditions (below 40 degrees).

Hope that helps you, you can always reach me directly at Matts@RJControl.com

I have the chance to purchase a Onan Emerald 1 Genset 4Kw rv generator and was wondering your thoughts on this model? This would go into our race trailer.

They were good units.....but that would be a pretty old unit. They have not made that design for over 10 years. Did it have an hour meter attached to it ? It's always helpful to know the amount of usage on a machine of that vintage. An hour meter is the closest thing to an odometer.

I would not buy one unless it looked to be well cared for and could be tested. It is very easy to run one even if it is not installed in anything.

Add a battery and a gas can and run it and check the output voltage. I run every unit I work on....on a bench and it gets load tested with a resistive load bank to full rated load.....It's a lot of work to install one in a trailer or M-H so it should be confirmed as good before doing an install....

The hour meter has 232 hrs on it and the unit does look to be in good condition. What is the noise decibel on one of these units? There are asking $500 for the unit.
Thanks

Buy it.....They are very quiet. They made about 3 different styles of mufflers and you would need a below the floor mount for a trailer.

They run at 1800 rpm and that helps keep the sound down and is also why they lasted a very long time usually. They can go for thousands of hours with proper service. Sounds like you found a good one but it should be run tested....
