Injection Pumps 101

[Jim Sutton]

I am in the process of rebuilding my 84 300SD engine and wanted to get a better understanding of the dos and donts of my IP pump. There does not seem to be a lot of detailed information avalable on it and I understand that there are settings on the pump that can only be made be a tech with the proper test equipment.

I was hoping this thread will give a better idea on how it works and what things can be inspected and adjusted.

So I am going to point out what I know and ask a lot of questions.

I took several pics of the pump out of my new engine. The pic below is the end of the pump next to the oil filter.




I have some more pics to come.

Thanks, Jim
