400D Hydraulics

At idle, maybe 1000 with a new pump. At load speed, 1400. Used less. Though they look alike, the Diesel pumps turn opposite of the gas pumps. Good luck finding a good one. Jim
 
This seller on ebay rebuilds these pumps. I talked to him in person and he seemed to know what he was talking about. It comes with a 1 year warranty. If you open the "Full item description", it talks about the diesel pumps.

If you go this route, I'd love to hear your results. This is what I was planning on doing if needed someday.

Another possibility is a pump off a gas or diesel -9 series, they are also counterclockwise pumps.
