Default Re: Onan emerald 1 genset manual

Hi, just got a motor home with 4000 Emerald Plus
4BGEFA26100P Spec P

Seems to run OK could be a little smoother and make quite a bit of noise. My old EF2500 Yamaha seems quieter. No hour meter on this one. I'd like to start by doing a complete service on it. I was steered to this site and glad I found it. I someone could send a manual it would be greatly appreciated. hjunderwood@comcast.net
Thanks

Two types of noise exhaust and engine noise. If it's engine noise can try adjusting the valves if they sound noisy.

I use a wood broom stick to probe around the engine to search for area that's making the noise. I cup end to my ear and listen. Use a hardwood broom stick if you want to hear the high frequencies better. With soft wood you hear less of the high freqencies.

Thanks for the link and advice. I do want to check the valve clearances. What I hear is more mechanical noise than the exhaust. It has a new muffler. I also think some sound deadening would help greatly. The way the manufacturer installed it leaves a lot of room for improvement.

Lightbulb Re: Onan emerald 1 genset manual

I have purchased a Ford Tioga 1986 motor home. It has a GenSet 4.0
I quote:

"Do you have a link for the "C" spec ? I also have the Emerald 1, but I think I have the C spec. My model is 4.0BGE-1R/26100C.
I couldn't negotiate the above site to find the manual."

I too would ask for a service manual. Onan emerald 1 genset manual.
Thanks for the site.

Eric
