After getting help from someone contacted on another forum we finally got it running again. After double checking we on the right TDC cycle, and finding our fuel pump timing was close we kept cranking with fuel lines at injectors cracked open for much longer than we had done before - apparently this time was the charm - it started - YEAH!!!. And it restarted the next couple days. In hindsight, perhaps we didn't have to replace the cylinders but who knows now. Before putting backhoe back on and fixing couple remaining hydraulic cylinders we decided to see if can fix differential brakes that prior owner never remembers working. Still struggling to get Carrier Assy plate off so can replace the seals that clearly failing. Have brake parts cleaned and ordering replacement parts.Ken, any news on this rebuild? Just read the thread and have interest in how this turns out. I am currently working on a "deal" for a 580 CK myself and was looking into these forum threads to get a peek as to what I might be getting into with the CK. I apologise that I don't have any advice for you as I have never owned a diesel whether car, truck or tractor in my life so no help there. I am following this thread however, as I like a good "eureka" story and I'm hoping you find the issue to be one of the crazy simple things since it doesn't look like any of the major issues. You seemed to pretty much cover everything. Good luck. Keep us posted please.
This project clearly the worst "free" project ever tackled. Ready to call it quits after about $5,000 of parts but my son kept thinking one more thing will get us there - now passing $9,000 but "think" we are very close to having a working backhoe (that might be worth $5000?). Hindsight: should have put same $ down on newer machine/mini-excavator. Despite $, big plus was having our son come home frequently to spend day working the problem - greater bonding/appreciation. Thanks also to this forum and another one.
