Default Another Onan DJC

Ran across another 12.0DJC with a 4R code a few days ago that I can have for shipping, (or pickup). Been underwater so probably stuck good. It is an older set with "Magneciter". The tag is gone but from writings in a note pad I'm told it was a DJC-4R series. I have the balance of the numbers but the pad is at the shop.

What is the "4R" meaning? Is it not reconnectable, or is it not 120/240 available? I know a "C" means reconnectable and "R" means remote and neither is in this unit.

Thanks,

That is 120/208 4 wire. "4" is the voltage code.

4r is usually 120 208 3 phase only.. can have 3 120 lines or 208 single phase with 1 120 line just have to balance the loads..

If it's been under water consider it parts especially if it was salt water

It powered a boathouse in Missouri. It's never been in salt water, (that is known) but the area floods a lot and it's not been used in years. Belongs to a 2nd cousin's dad whom is going to demolish the structure.

I don't know about the tin on it yet but supposed to get a couple photos today.

Thanks,

Probably worth a trip to pick up. There is some chance it is useable. 4R is not the worst voltage code to have. Obviously they managed to use it for their building. Cheers Dan

I remember the place in the late 1960's and early 70's which is one of two times I was there. I'm told most of the boathouse has been torn down where they used to hold river parties, but the winch house and dock still stand now having commercial power. This generator has not been used in many years and has been submerged several times. It was not replaced.

I didn't get the photos I was looking for today.

Forgot I'd had this. Pulled it out of an e/g replacement project where engine was blown and replaced with a Kohler set. Found it in back of shop as I was cleaning. I'd kept it to install in the basement of my house when planning to install my "EF" set permanently. I'm finding stuff I've not seen in over 10 years and am absolutely fascinated at how much "crap" I've stuffed into that building since tiring of, and closing the business 11 years ago.

That DJC is a mess. It was a vacuflow type and the housings are all rusted off of it. The generator section in the back would need to be forced apart as rusted solid between the rotor and stator. Mice have certainly taken favor to it in the past also. The set has actually fallen through the floor partially as the joists below have rotted away over the years. I was told there was only water in the pan, no oil, so I'm going to let this one go.

That's too bad about the DJC, but sometimes you just have to walk away.

Seeing that ATS brought back old memories. I installed a bunch of them. At one time, Onan/Cummins was trying to standardize on enclosures. For a while, 150-400 amp OT switches were in enclosures that looked like that. A standard 150-225 amp ATS that size is ridiculous. Unless it sat on the floor, we had to gut the switch and remove the door to install the enclosure on a wall.
