My 4x4 diesel 1710 (acquired with the house I bought, history unknown, but definately not well maintained) is having a fuel injection pump problem.
I've got fuel to the pump and over to the pump bleeder screww but that is it...nothing up to the injectors and further trouble shooting shows nothing at the output nipples to the fuel lines to hte injectors.
Under an inspection plate are three small springs that look very similar to valve psrings. Under each spring is a lifter which appears to be cam driven....the cam is spinning (it's integrity is however unknown) and the lifters are pumping, but they do not seem to be compressing the springs above them????
THe lifters appears to be bolt heads (actually two of them) and they seem to spin up or down. I can adjust them to get movement on the springs, but now a strange sound is originating from the pump. I'm at wits end.
Are these lifters adjustable? Any one know specs or what is actually required to effectively adjust them? Does the fact that they need adjusting something bigger in and of itself (worn cam shaft lobes????) I assume that removing the pump to replace a cam would require reaquiring injection timing....Is this something beyond the shade tree farmer without a shop manual?
Any help would be appreciated.
Thanks,
J Bear.
