Default Re: Unknown Barn Find Ecotrans? Help!

More detail to be added to my original posting: If yo are considering purchasing one of these APU's - there are several different configurations. Some had belt driven large circulating water pump instead of driven of the end of the injection pump area. The exhaust, intake filter, control box, and other small stuff is mounted in several diff. ways. I mention this mostly to evaluate a unit of interest. They were built to be mounted inside the sheltered body of the locomotive - it is an open top frame. If they were stored outside in a surplus yard there are opportunities for weather damage from rain getting into critical places - like intake, exhaust, control box, etc. Some of the units have missing components - probably robbed from down units to fix others.

Of the five I've looked at, all were low hours - under 2002 hrs. - This leads me to the theory that the railroad maint. workers had trouble keeping them working for minor stuff that I mentioned earlier. They were in service less than 5 years. Mine had 1700 hours, a new battery, and no signs of real wear.

I know this is an old thread but I own one of these APU's as a house generator. I used to install and set these up in CSX Locomotives back in early 2000. I have the manual that came with these units. PM me if you want a PDF copy emailed. It's too big to attach to the forum. I also have part numbers for parts. Snyder Equipment will sell you spare parts but they are not cheap. Like some others have said, there were several MOD's done to these that didn't work out to well. Let me know if you have any questions or need help. I have mine working great using all the onboard locomotive inputs.

Brief specs to know:
16 KW max output at 66 amps (240 vac). CSX under breakered them at 50 amps due to the high temps in the locomotive car body
Pump off the back of the injection pump accessory drive is an oil pump for locomotive oil. It can be removed if you don't have the Snyder upgraded automatic oil injection system. DO NOT run that pump dry or it will lock up and break your injection pump gear set. And that is costly to fix.
Engine is cooled by a heat exchanger that uses the locomotive cooling water to cool the Kubota. To use as a generator for home you will need to install a radiator. Snyder modded these unit to have a radiator because the heat exchanger's were notiorus for plugging up and overheating the Kubota.

Of course if any of you have parts you don't want or will not use, let me know. I am always looking for spare parts.

Hope this helps.
