| From picture, I can tell nothing. If it is leaking between adjusting nuts, there is a oring inside. If it is leaking at nut on drip tube, there is a rubber bushing in nut. If it is leaking where injector goes into head, replace the valve cover gasket. MACK |

Inj has to come apart to replace the oring inside. That isn't an original 210 injector. It will need reset once the adjusting nut it removed, and oring is replaced. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

| Thanks Ed, I pulled the injector and took it to the neighbor who has a injector tester. He took it apart replaced the oring and set it at 3100 psi. I put it back in and no leaks. He seems to think those injectors are out of a 7000 series tractor. Why would someone have changed them from the originals? Any thoughts of why they would have changed them out? |

Being there not original I would pull the other five cuz you have no idea what they're set to now you got one correct and 5 maybe something else ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |
