Stanadyne DB2 diesel injection pump repair Part 4 of 5

[@wufpakfan88]

I live in Jacksonville NC and worked at the Stanadyne plant in town from 2004 -2011. I helped assemble thousands of these DB2 pumps and watching this video brings back some great memories of my time there. I never got to see the end result of my work there but watching you disassemble and clean this pump is wonderful and fascinating.

Several years ago, I did a Roosa master pump, out of an early 70's Oliver tractor. Same design, just a fantastic example of a properly engineered device. Thanks for watching.

small detail noticed... the gasket and seal kit you used is for industrial/agricultural applications. there is another gasket kit for Ford/GM automotive kits. that would explain the differences you noted (only 2 umbrella seals, etc.). The Stanadyne automotive kit is PN: 24370

I grabbed up a space kit number 08793 For bd 2 pumps as well ym this has the 3 umbrella shaft seals. I'm not going that far , this has been rebuilt it landed in a bucket of water. Um I'm impressed not bad.

Thanks for the part number. Hope it helps anyone else doing one of these.

Didn't seem too bad to reassemble it. I was watching Salvage Workshop a few weeks ago or so rebuilding a pump from piece of heavy machinery, and he had to remove the replaced umbrella seals, and reinstall them while reassembly of the pump body unto the machine took place because of space. It was something, but it worked.

Maybe if a guy needed a seal install for that main shaft, 3D printing might be an option. You'd probably have to sand it and file down the seam.

Good iinstruction overall. Unfortunately, the advice you gave concerning the cam is just passed along false info, even though you got that info from a seemingly expert source. I heard them say it, too. The pump is designed to operate either clockwise or counter-clockwise, correct? The way you change that is to flop the cam over. It has arrows on both sides. This is the design, so it can run both ways. If the line over the hole always has to be at the top, then the pump can only run one way. So you are saying it can be put together to run only one direction, but that is not what it was designed to do. The correct question should be: which way should this pump run for this application? Then set the cam for that direction. Best case scenario, you marked it when you took it apart! Otherwise, you are in a guessing game. And that hardened steel is difficult to mark. Need a paint stick or something.

I talked to a technician who rebuilds them. He said he doesn't pay any attention to the inspection hole theory. There is a "hole" in that theory. Look at the arrow. You need to know which direction it should go for your application. Mine is for a Ford 7.3 idi, and it goes clockwise, looking from the drive end. End of story.
