Gentlemen:
Good morning! My bride joined me at the Generator (date night) last nite and she directed us through Jerry's thought process:
*she ran the primer, lit up the glow plugs for 60 seconds,cranked it while I observed, solenoid works fine, free movement, no drop, stays open with and without the screwdriver, cranks/no smoke, 3 tries
*so I cracked open the fuel line at the #1 injector, she cranked the starter, and I saw fuel/no air, tightened
*same procedure for other 3 injectors, encountered air at injectors 2,3,4, bubbling out in spurts with the IP pulse, when it seemed to run clear, I buttoned up each one, cranked it 2 more times (15 seconds each) no smoke could be there is still more air in the system?
* a little background check: the day before, after I installed the injectors and buttoned up the system, I pulled the IP spring and primed the system, cracking each fuel line @ the injectors, in sequence (1 -> 4), no air visible, re-installed the spring, torqued both nuts, primed, lit up the glow plugs for 60 sec. and attempted cranking 15 secs each time, resting a couple minutes between each attempt, good cranking/no smoke
I was a CAT trained mechanic at the proving grounds in Peoria, worked mainly on the big dozers D8's-D11's, we would tear them down to the frame and put the experimental components in, put 'em back together and send back out for another 5000 hours, if the engine had a problem we just yanked it and put another in its place and let the engine guys work on it. If I am missing something or doing it wrong, I am certainly open to suggestions. After all Jerry's hard work and attention to the injectors, it is hard to imagine that the injectors are the issue, and the IP seems to be pumping along, and the solenoid appears to be functioning correctly.
Just want to get it right and hear this thing purring again. Thanks again. ZeusDiesel
