Stanadyne DB2 diesel injection pump repair Part 3 of 5

In this video series I show how to disassemble, clean, and re-assemble the famous Stanadyne aka Roosa master pump. This one is off my 1993 Chevrolet 6.5 Turbo diesel that after sitting several years, had the diesel fuel turn to a gooey mess.

Hello, I wanted to ask you how you test the transfer pressure of the Stanadyne db24. Greetings from Argentina

Could you tell me why my pump head got stuck? Is it because of some impurity?

[@jackdaicole7595]

Are there any manuals on these pumps? I own the 6.9idi and 7.3 idi

[@stevewatr]

I had trouble finding true service manuals for specific models. I think most of that info is kept under wraps by the manufacturers who only supply it to injection pump rebuilders. Luckily, the Stanadyne DB series has been around so long, that you can find plenty of older manuals just by searching "stanadyne DB2 pump manual" or DB4 etcetera. If you find a manual close enough to the model you have, you will at least be able to see how it comes apart, and maybe even some data on settings. I even found a manual that is a US Army technical manual that had good info. Like I tell people all the time, I'm not an expert, but I get lucky a lot.

@@stevewatr same here. Hey I got a question I have a 6.9 idi it started skipping loosing power leaking fuel everywhere. What I thought was a loose injection line turned out to be broke clean through. I shut it down and ordering new lines. Could this hurt the pump running like this?

@@jackdaicole7595 again, im not expert, but I think a long as fuel was moving through the pump it should not have caused damage. The fuel lubricates the pump. And the injectors do not pop off if the pressure is low due to leaks.
