Last Monday we were back at it with the "B".  Lots of piping that was removed by the copper thieves was replaced. This piping is used for everything including rain water drainage, control air, oil ( hydraulic  and lube ) and braking.  This pic shows an impromptu twister session that started while some of the copper lines were replaced that run up to the brake stand.

   

The big thing that we took care of was checking  all the interlocks in the electrical system that allow you to start and shutdown the prime mover.  After going over miles of wire and checking the action of about a half dozen relays and the emergency shut down circuit.  We hooked up some jumper wires from 664 so we could make our first attempt at rolling over the engine. With the engine pre-lubed, we opened all the cylinder cocks so there would be no compression, and kept the fuel pump off. Then for the moment of truth, we hit the start switch.
----------The engine rolled over nice and smooth, no clanking or hesitation. Just nice, even, constant motion,,,, exactly what we wanted. We have one more thing to address before we attempt our first start. It's a holding circuit that keeps the fuel pump turning while the engine is  running. We just didn't have enough time in the day to get that together.

Another bit of goings on is that the Nickel Plate geep 9 #514 is back in service.
