I'm looking for a parts number list for these pumps. I can order the parts from usdiesel but I dont have the parts numbers from stanadyne to give them. The pumps are off a JD 3010,2030,4040 that I own. Problems are governor ring in 3010 and leaking pumps on the other 2. Thanks for any help.
 
The seal kits are all pretty much the same for all the DB and JDB pumps as far as seals go. Some are just packaged with more extra parts then others. The plastic dampener ring that holds the flyweight cage together comes in the kits.
I don't use them. For an extra $50 you can eliminate the plastic ring forever.

I don't have a parts list for the DM pump.

JDB seal kit - Stanadyne # 24371 - Spaco U24371
JDB pilot tube - Stanadyne # 16320 - Spaco U16320
JDB pump vanes - kit 20803 - Spaco 09528

New style solid weight retainer #29111
 
Thanks for the info. Would you know the numbers for the metering valve,cam rollers and shoes and the part number to eliminate the plastic gov ring?
 
DM kit is 24372. Rollers 11141, shoes 20116, M valve 20849. 29111 retainer is used on weights with the sharp heel. Very late JDB pumps on 3020 and 4020 have the rounded heel and need retainer 27984.
 
Forgot, the 3010 needs the shorter brass tube, 16323. The drive shaft has an O ring to keep it in place and the shorter tube is needed, the O ring will catch the end so it won't fall out.
 
FYI, got JDB inj pump kit for 3010,replaced gov ring and seals, 3hr and $30 worth of parts and tractor runs great. Saved a bunch of money and down time not sending it off to pump shop. Thanks again for the part #'s.
