An outfit that i worked for around 1970 named Van Buskirk of Sioux City ,Iowa had about six-660.We were working on I-29 south of Omaha,Neb. Iowa side of the MO. river.
The barrow pits was right on the river bottom and they had 3 -8 inch pumps running day and night.There was over thirty scraper hauling out of the pits.The pumps couldn't keep up with the scraper and as the day went by ,more water was coming in then out.
Before the day was over there would be over two feet of water that we were trying to lot the sand out of.You would have to keep looked over toward the barrow pits banks to tell if you was moving when the 9's was pushing you.You would have as many as 4 to 5 9's pushing at once.Usually 2 D9G's and the others we old torquer 9's (19 series)??
The sand was hard to load with out speed.You just had to keep try pumping it in(raising and lowering the pan).When the water got real bad it was harder.You would at times have about as much water in the scraper as sand.
They had a hole over to the one end of the pit that they dug with a dragline to set the pumps in.We would start working in the moring next to the hole,cutting it lower there and work our way out from it trying to keep the bottom graded back to the hole for the water to drain back there and not out where we were working.Worked for a while ,but water was coming up to fast for the pumps to keep up.
As for the 660 turbo and heads and so fore i know about that.I was coming out of the pit and the turbo came apart was first thought.Pieces throw.I told the mechanic
ointhead that there was some good sized piece.
They replaced just the turbo, smoking terrible and no power.Long story! They tore it apart again thinking it was the head.Replaced one head.Instead of taking off both.Wrong head.Still smoking no power.They said run it.So i did.
Finally the valve in the bad head went down through the piston.Needless to say it sat there for a long time after that.Memory lane !!!!!:drinkup :usa
