[QUOTE="Jyuma, post: 43319, member: 4393"] Success!!! Today the engine came to life for the first time in at least 3 years but not before a final round of problems. The high pressure fuel lines were corroded at the connectors and I had to take a wire wheel to them. The fuel line from the fuel pump to the injector pump was clogged with a combination of rust and brown muck, so I replaced all the fuel lines from the tank to the injector pump. Once I was getting fuel to the injector pump it wasn't pumping fuel to # 4 cylinder... stuck valve in the injector pump... so I disassembled the injector pump and gave it a thorough cleaning. Of course I learned the hard way that the only sure fire method to bleed the high pressure fuel lines is to loosen the nuts on the top of the injectors and crank the engine (decompression lever engaged) until you see fuel welling up from around the nut. Be sure to re-tighten them all. When the engine first fired the entire area became filled with dense smoke as the residual oil and extra fuel was burned off but within minutes she was purring like a kitten with no smoke at all. There are leaks galore with hydraulic fluid oozing from seals and fittings but nothing serious enough to stop the controls from working. Thanks for all your help... I couldn't have done it without you. [IMG]https://www.skidsteerforum.com/DesktopModules/AdverForums/ImageGallery/emotion-1.gif[/IMG] Ed [/QUOTE]
