How I tested a Onan 423D diesel engine (with videos)

Posted by Ignoramus31708 on October 21, 2006, 7:21 pm

Bought if from the military for not too much.

Note that you will hear sound "cutting out" in the videos, that's
something wrong with my camera (or how I use it), the engine keeps
running. The last video meant to show how to stop it by cutting out
12V power to the fuel shutoff valve.

Do not click on the high quality videos link please, they are too huge
to download.

A lot of people are trying to download videos. They are hosted on my
home computer, so download will be slow. Please do not hit RELOAD in
the middle of a download. It is slow because there are so many
downloads. All the videos are there. My internet access slowed down to
a crawl, but, I think, all my pages should work for you if you are
patient enough. Sorry about it. It should become better in maybe 1
hour or, likely, much less.

I have no idea. Good question. Why would you want to fit a turbo to
it, if it runs fine already?

The best use fot it would be to set the speed to 1,800 RPM with the
governor, fit a generating head to it via a splined shaft and U-Joint,
that would give you a near perfect generator. The minus here is that
it will be relatively bulky, but it could put out 20 kW 24 hours a
day, 7 days a week. These engines were fitted to Onan generators.

I found info on those generators in Google
