Thanks for that. I will take more pictures next time I see it.
I am looking to buy the unit. It is an Onan 12.5kw.

Just thought that the Model # and Serial # might be of help to identify.

Thanks, Iver.

I looked up the 3A1 number. It shows to be a 15KW unit. But it doesn't tell me the Onan/Cummins code. I will see what I can find.

Thank you....
I was told the genset is a marine model.
It was removed because the heat exchanger failed so they replaced the complete generator with a new unit. My plan would be to convert it to land-based and install a radiator.
Thanks, Iver.

Going to check out this compressor tomorrow.

What should I look out for or what should I be aware of when looking at the unit?
Thanks, Iver.

Make sure it turns over. Should be a little hard from the compression.
Look it over for damage has it been hit or dropped.
Check the oil for water.
How rusty is it. Will have some but not to the point. Where parts are falling off.
Check the controls for burns or damage. If the wiring is burned you will smell it.
Check for damage from mice or bugs.
Is it what you want.

Does it start easy , does it make power, does it smoke. A corroded heat exchanger is not a very good reason to replace a working generator . If it is the same one that has been for sale for a couple of months . If the hours are high it may need some engine work.Cheers Dan

I was thinking that also. Why change the whole unit over one part. I would look it over very well.

Salt or fresh water? Check for corrosion!
