Dr, in the 210 sn thread you had inj pump info on the 210 and 220. Do you have pump info for D21 s1 and s2? Have a couple pumps and thought they may be D21 stuff.

Thanks

While I'm not the Dr, I can answer a little. 
The series 1 D21 pump would be DCGFC629-2AG 84-88cc @ 2200, 88-93cc @ 1200
The series 1 D21 converted  DCGFC629-47AG 99-104cc @2200, 102-107 @ 1200
The factory series 2 D21 is DCGFC629-25AG. 102-104cc @ rated 2200, 105-114@1200
As stated, all very similar, non advance pumps with electric shut off solenoid.
The 25AG is the hottest set one of the 3. Not sure which one was on the neb test tractor. The 25AG has the strongest torque rise, though the hp @ rated speed would be nearly identical to the 47AG

I've got some old info that the 128 HP D21 had 468 ft lbs peak torque, while a 131 HP 5020 John Deere (531 cubes no turbo) only had 371 ft lbs peak torque. Which one would you rather pull a 7 bottom plow with ??????? !!!!
