Hey all: I have a 1987 Case 580K with Case/Cummins 4-390 non-turbo diesel engine. This machine sits at my cabin most of the time, and I occasionally dig and plow snow with it. Yesterday, after filling the fuel tank and running the machine for 1 hour, I was driving up the road and felt something funny (intermittent lowering of cruise RPM with constant gas pedal position). I turned up my [steep] snowy driveway, and about 1/2 way up the engine cut out and died. Restarting failed. I quickly got the "fuel system" section of the service manual on my phone, grabbed my tools, and proceeded to:
I did some work with the backhoe for a while after all of this, and the engine seemed to run perfect. Perhaps the water was purged in the process of bleeding/draining. What I'm wondering now is what to do next. I've decided to have a spare lift pump on hand, and to get new fuel filters (primary and secondary, plus the inline fuel line filter). I also thought it would be good to add some diesel water dispersant, like Diesel911 to break up any remaining water droplets so they can mix with the diesel fuel. Perhaps treat diesel regularly with Diesel911 when these weather conditions exist.
Does all of this sound reasonable? Now that I know how to work with the fuel system it's not intimidating at all, very simple. I just don't want to have the machine die again in a bad spot if there's something I can do to prevent it.
Thanks,
Gavin
- Drain some fuel from the fuel filter
- Bleed the fuel filter housing bleeder
- Bleed the injection pump bleeder
