So I was all ready to move this machine yesterday. I had used it the day prior for about 10 minutes leveling off some ground, it ran fine. The morning of the move it ran fine, throttled up ok. Hour later when I went to drive it on a lowboy, no matter how high I put the throttle, the engine would not gain RPM's. it was just stuck at idle, until finally it died and would not start again. All the linkage moved freely, decelerators were not stuck etc.
I checked:
1) No clog at fuel tank, the small strainer there is clean.
2) The fuel filter looks decent, nothing majorly wrong with it as I can tell.
3) The fuel canister only had about 1 inch of fuel in the bottom of it. The canister is not being gravity fed by the tank for some reason...
I notice the hose from the tank does not go directly to the fuel filter canister, it goes to some sort of manifold, or is it a PTO driven fuel pump? I'm getting fuel up to that point. I can't get my hands in there or even see where the output hose is connected.
The Fuel canister is definitely lower than the tank, so to me seems like it should just be gravity fed?
I guess my question is, to get this thing loaded can I just rig up a temporary fuel bypass hose from the tank to fuel filter canister to get this machine moved? Or does the fuel filter canister actually need to be pressurized?
I will say, I had to steal most of the fuel from this machine to get the
Hitachi UH122 moved (after the loader "ran fine"). There is about 5 inches of fuel left in the bottom of the Komatsu tank. To me that seems like enough to gravity feed the fuel canister? However, I think the first thing I will do is steal about 30 gallons of fuel back from the Hitachi and add it back to this Komatsu to see if that makes any difference.
Hard to believe it's as simple as the fuel level? The dipstick shows about 110 Liters (30 gallons).
