Hello all:

Did not want you to think that this was an ask and run. Long story short, I bought a complete rebuild kit for the fuel injector pump, carefully disassembled the pump, installed the replacement parts and reinstalled the pump. No joy. Removed, repeated the disassembly, inspection and reassembly. Again no joy. Tried a third time and gave up.

I sent the pump off to BK Diesel in Iowa, they did not laugh when I told them of my woes, gave me shipping instructions, promptly fixed the pump and returned it to me. Good communication and nice people.

Today I installed the fuel injection pump, connected the lines and the machine roared to life. Ran a little rough for a few minutes then smoothed out.
I put her to work, light duty at first then moving dirt at 3/4 throttle. Machine runs like a top.

Thank you to all that offered assistance, suggestions and ideas. They are greatly appreciated and I hope I some day will be knowledgeable enough to return the kindness.

Rick

By chance did BK Diesel tell you what was wrong or different when they rebuilt your pump? Just wondering what they did that you missed.

There were several things. The cam for the HP side was in backwards (one way for clockwise rotation flip it for ccw) There was something else that they explained that I did not fully understand.
