Does anyone have a Transfer pump in good working order?
Have a D2 3J3006SP it will not make any fuel pressure while cranking, have checked spring and bypass valve.
Will not fire on diesel.
I don't have a spare, Anthony, but does the pump turn? You could whip the cover off and bump the engine over to confirm that it's turning.
Dose anyone have a part number for the transfer pump assembly
It doesn't take a lot of primary pressure for your D2 to start and run well, air is the more likely problem. You could try pressuring your tank like the guy above. If you get it running you may see pressure on the gauge. Chasing that transfer pump may be a long lonely road to nowhere BTDT.
Nice HG you have there. I just bought one to replace the one I sold in 1966 to buy my first D2.
My 5U doesn't show any transfer pump pressure when the engine's idling, and barely shows some at full power. I've not measured the actual pressure so I don't know if it's low or the gauge is faulty, but the pump itself wasn't the greatest so it wouldn't surprise me if it's low, so like 8C said, they'll run so long as fuel actual gets pumped airless
I have bleed all the air out but it apears the injectiom pumps are bypassing internally,
as they are not squirting any diesel into the pot.
Rack is free and moving.
If i hook up d2 injector onto our D4 fuel pump it squirts straight away.
Looks like in need to find 4 injector pumps
Just for grins, try turning the rack quadrants further than the rack would allow. You might have quadrants that have moved on the plunger. They're aligned at the factory but it is possible to mess with them and misalign them. As far as I know, there is no published info on how to correctly align the quadrants, however I'd wager that a good injection shop could do it by trial and error - figuring out where low and high cutoff are, and what the quadrant range is, and then setting them a) into the correct range and then b) fine tuning each pump so that they pump the same volume at the same quadrant angle

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
