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.
