I was able to obtain the actual International 7.3l shop manual. In the last section of the book, it gives complete disassembly, inspection, and assembly instructions of the Stanadyne DB2. I decided to rebuild my original pump after my remanufactured injection pump gave me hard hot start problems. My original problem was a miss at over 1800 RPM. Turns out it was the advance piston that was scored up and worn into the aluminium housing after disassembly and inspection. So I tore my pump right down, cleaning each part one by one and putting the parts into a clean tub of fuel additive until ready to be put back together. I took my questionable parts to the local injection shop and they were able to fix me up. I bought a new oversize advance piston $30, had them hone my housing to accept the new piston ($10 labor) bought a complete seal kit $54, installed a new delivery valve $5, a new metering valve $25, a new cam for the external advance mechanism $35, I was going to buy a new governor flyweight thrust washer, but they told me just to flip it around to give a new surface for the flyweights to run on. Oh and for the $10 they charged me to hone the housing, they also installed my seals on the pump drive shaft because you need a special tool to do so. Once I had everything back together i took the pump assembly to the injection shop for calibration. They charged me .5 hr labour ($40) to calibrate. When i went to pick it up they asked if i wanted a job. The pump has been going strong for 10,000 kms now ! Best of all, it's the original pump to the truck! One heck of a learning experience.
