Sooo, who's a lombardini diesel expert?

Recommended Posts

I am working on my diesel. I am only getting fuel to one cylinder... I cracked the line at the injector and at the base of the pump and nothing on one cylinder. I also opened the bleeder on the pump and it was presurized. Opinions? Obviously its in the pump...

Not an expert but I have taken the pump apart. With shop manual and parts breakdown it's not too bad. May see what's up. Might be disintegrated O-ring plugging up a passage. SmilinSam's son is a diesel mech and knows much more about this. Otherwise take it to a diesel shop.

I would also suggest removing the pump and see if the metering valve slide or piston plunger are stuck. Low sulfer fuel and low lubricants in the fuel, something could be binding up.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
