    Loss of Power after Coupler Replacement

    OK, today’s troubleshooting. I figured I would go back to the beginning on the not running thing. I started by removing and dumping both fuel filters, blowing everything out good. I reinstalled both fuel filters after having everything nice and clean. Switched the key on, the small inline...

    Loss of Power after Coupler Replacement

    I went back out and with @ little help I bled the injectors. A couple of them seemed to have a lot of air, a couple not too much. That did not make a difference either.

    Loss of Power after Coupler Replacement

    Nige, not doubting you, you obviously know a bunch more than I do on this stuff. It seems if that is the only test, you’re indicating the fan itself will never fail?

    Loss of Power after Coupler Replacement

    OK, today’s troubleshooting. I disconnected the inlet fuel line to the inline fuel filter and used my compressor to blow out the fuel line to the fuel tank, at this time I did not drain anything from the fuel tank. I started the unit, it ran very rough for approximately two seconds before...

    Loss of Power after Coupler Replacement

    This will be today’s project. The comment on testing hydraulic pressures was referring to the very beginning of this mess. Everything I read and everyone’s thoughts and suggestions was the coupler. But I could not find anything, anywhere on how to actually test it. It was all remove the engine...

    Loss of Power after Coupler Replacement

    Since the beginning of the problem, I’ve tried to figure out how to test the hydraulic pump. I’ve thought it would be simple during building to put a couple of connectors on the output side of the hydraulic pump and motor to connect a pressure gauge and check pressures, but they don’t. Until...

    Loss of Power after Coupler Replacement

    Recap of everything and update. Serial Number DX200203, ECM HW PN 3693556-03, ECM SW PN 5836260-00. Long story short, the engine to hydraulic pump spun. I pulled the engine and changed the coupler. Got everything back together, wouldn’t start due to “E459-2 Machine Engine Rated Horsepower...

    I was mulching in small brush thicket when I lost all power.

    Loss of Power after Coupler Replacement

    UPDATE: I changed the inline fuel filter today and it is better but continues to drag down when using any power. Sitting still, at full throttle it runs about ~2500 rpm. If I engage the mulcher, it bogs the system down (if I’m just idling, it will kill the engine). It even bogs down if I’m...

    Loss of Power after Coupler Replacement

    Good day everyone, yawl recently assisted me troubleshooting some codes after I pulled the engine and replaced the coupler on my 2015 299D2 XHP (S/N: DX200203). Today I decided I would run out to woods where I left my John Deere MH60 mulcher when the coupler went out. I noticed a few things as I...

    Error Codes & No Start After Replacing Engine/Hydraulic Pump Coupler

    Nige, thank you! Following your procedures the gauge faulted and the E459-2 code was the connector to the ECM. After I disconnected and reconnected and wiggling it ensuring I had a good tight connection. The 1704-5 code was a plug on the hydraulic pump/motor. Everything is back to normal. I...

    Error Codes & No Start After Replacing Engine/Hydraulic Pump Coupler

    I pulled the engine to replace the engine to hydraulic pump coupler on my 299D2 XHP (S/N: DX200203), changed the coupler, got the engine back in. But now I have a couple of other issues. It powered up normally but I have a couple fault codes and one gauge isn’t working says FAULTED. The codes...

    299D2XHP Not Cranking

    Cliffs, best advice ever and I should have known this, the “KISS” concept (Keep It Simple Stupid). You’ll never believe this… I was messing with the machine again today after taking a little break. A friend of mine has a mini excavator, we were talking about my problem. He mentioned he had a...

    299D2XHP Not Cranking

    No sir. Had to take a break to get the yard mowed and a few other things done. I hope to get back on it today.
