D600 govenor screw
 

In my ignorance one day I messed with my 1572 govenor screw thinking it was the fuel screw and thought I put it back where it was from factory but not sure. Now it leaks oil there a little. How do you know where it should be? thanks Bluford IL

Since there are several screws on the governor, all of which are exposed to oil on the backside, please post a picture so that we can help you with the right solution.

Sorry my computer isn't working right to send pix. It's the screw in front of the injection pump that should have a no tamper screw on it. I messed with it now I am not sure exactly where it should be. Thanks Bluford IL
