Just an update on this problem. I was able to get a new hydraulic head from a guy in Olympia, WA. (He deals in Buda diesel parts so some of them must use the same pump). Anyhow, got home last night and went to work on the M35A2 this afternoon. The hydraulic head gears did have a tooth that was scribed, but not painted red. I used a paint pen and marked that tooth. I reused the thrust button and keeper from the old unit, as well as the fuel pipe fittings front and back. I used two new O-rings on the hydraulic head and got it set down in the body, with the red tooth timed to the arrow on the case. I installed the shut down shaft, being careful to line up the slot in the shutdown collar with the small rotating lever in the end of the shut down shaft. I used a new O-ring on that shaft. I lock wired the appropriate screws in the shut down box, put the keeper on the shut down push pull rod and reinstalled the cover. Then I reconnected the shut down cable to the control. After that it was just a matter of putting the lines back on and checking everything. I ran the electric fuel pump and cranked the engine for a few seconds. Then I finished tightening the high pressure fuel lines at the injectors. When I again cranked the engine, it fired up after maybe 5 seconds of cranking. It ran great, idled nicely and showed about 65 psi on the fuel gauge I had installed at the vent on top of the secondary fuel filters! Now to recheck that all is tight and no leaks, then put the left fender back on again.
Thanks to all the great folks who helped with posts here and to Brad in Mckenna, WA for his phone help. Now I can finish getting the truck serviced, outfitted and ready for the AC12 convoy to Alaska this summer. I am hoping to make the Arlington, WA display in July, prior to the Aug AC12.
