Hey everyone, I'm trying to help out my elderly neighbor with his L2350 and so far I am failing! I have a lot of experience with gas engines/automotive but quickly getting a crash course in diesel...
The tractor will start and run great when it's cold. It will run well for about 30 minutes, then suddenly start to lose power, eventually stalling the engine. If it sits and cools back down, we're back to running well.
I've replaced the fuel feed hoses from tank->filter and filter->injector pump. The fuel filter is new. I bled the whole thing from filter to injectors; the bleed at the filter is clean, no air.
However, I get a continuous stream of tiny bubbles (sometimes big) from the bleed at the injector pump. I also get continuous bubbles at each injector on the engine (cracking them open ever so slightly while the engine is running.)
After it does stall, I can restart the engine and it will run for a few seconds and then die again.
I should mention that the tractor only has 570 hours on it, so not a lot of use.
It acts like a brake bleeder that is pulling air in from the threads, but I'm making sure that I only crack it open just enough to start the bleed process, so I don't think it's that.
It seems as if it is pulling a small amount of air in from somewhere else, so I'm polling the crowd to see if anyone has ideas on where to start. Bad injection pump gasket? A deteriorated o-ring somewhere? Thanks!
