    Cat D5G HYDROSTATIC ECM light Illuminated, NO START

    I got it sorted out, it was the starter relay that was bad. But I guess the machine didn’t like the generic ignition switch so I put the old one back in so now it starts fine with no ECM issue. The 12.21 Volts was my battery strength with the key ON, not the voltage while cranking. Funny you...

    Cat D5G HYDROSTATIC ECM light Illuminated, NO START

    Hello, 2005, Cat D5G (RKG01078) I have been having delayed start issues, i.e., move the key to start and nothing happens for several seconds. Sometimes, more recently, i have to return the key switch to OFF, then try again. Only once have I seen the red exclamation light illuminate during...

    Isuzu 4BG1T vibration: Eating Hyd pump coupler and speed sensor

    Miller, Check the rubber dampener on the front pulley at the water pump/fan. As Simon says above, they may look fine but can have just a little play, as in my case, to cause a vibration at low RPM. That was my issue too. My oil was clean so I ruled that the lower part of the crank eating...

    Isuzu 4BG1T vibration: Eating Hyd pump coupler and speed sensor

    Engine off. I took my big pry bar to them but it didn’t move. Maybe I should take another look at the front mounts.

    Isuzu 4BG1T vibration: Eating Hyd pump coupler and speed sensor

    Doesn’t the thrust bearing sit on a concave washer/sleeve? I’m guessing as someone told me it’s a possibility. I believe the vibration has been with the machine since I’ve had it and graduated a little. In the cab I don’t feel anything abnormal.

    Isuzu 4BG1T vibration: Eating Hyd pump coupler and speed sensor

    It has 5800 hours and by variant I was referring to the different models. Mine is a DD-4BG1T and it’s the original motor. Good idea, I should probably pull my front pulley and check that too. Thanks for the insight

    Isuzu 4BG1T vibration: Eating Hyd pump coupler and speed sensor

    My 2005 LBX 160LX, SN K2J4 8450 (160Q3-1351) has an Isuzu 4.3L (4BG1T variant) engine that has a sharp vibration that I suspect is causing the flywheel to rub the housing and hit the engine speed sensor. It seems more pronounced at lower rpms. The engine runs fine. I removed and replaced...

    D5G Idler lateral and vertical play

    D5G, RKG01078. Hello group, I'm learning my machine and need some advice on the track system, in particular the Idlers. Both of my idlers have lateral and one with vertical play so my questions are: 1. What are the tolerances for movement both vertically and laterally? Obviously mine are...

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    Here is the #7, 1.5k ohm resistor that was missing from my fuel gov, regulator. It cleared up my E0025 code. And I may have solved my Electrical Prob as I replaced the Engine Speed Sensor (E0042) and have run it a little with no errors or further codes.

    333D face seal repair

    I have dealt with CR Components several times and can attest that they provide incredible support and are highly knowledgeable on the Fairfield, Torque Hub final drives. Not having any prior experience rebuilding mine (331G), they guided me through the process with great patience.

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    Where did you find a new harness for the fuel gov? Were you able to get just the harness or did you have to buy the entire fuel gov? Yeah, that's my plan, just add a new resistor.

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    I'm closer to solving at least one issue, E0025. The Fuel Flow Regulating Resistor is actually external to the engine and fuel injection, Electronic Gov. Off of the main harness for the Electronic Fuel Governor are these two wires that should have a resistor attached. As you can see, mine is...

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    Hi Uffex, I've looked everywhere for that engine, fuel flow resistor but I can't locate it. I've studied the pic you send me but I'm just not seeing it. Do you know where I should be looking? Is it near the starter side? On an unrelated issue, my local LBX dealer told me that I need to...

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    D do you recall the name of the part? I see one harness on top of the fuel injection pump with two wires on top of the fuel rail…not sure what that does.

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    Tha Thank you for that diagram. I started with the lowest echelon level with filter changes and cleaning the little screen in the supply feed pump. The dealer recommended I replace the Return to Idle sensor. I’ll try that next week when the part arrives

    Linkbelt 160LX, ELECTRICAL PROB, Code E0025

    My 2004, Linkbelt 160LX, S/N K2J48450 gives me an intermittent, ELECTRICAL PROB but then goes away when I shut it down with an immediate restart. I troubleshot with the service manual and the only Error code that I have is an E0025, "Fuel Flow Regulating Resistor." The diagram shows this...

    Cat D5G, Joystick Control Module Repair; S/N RKG01078

    I have the parts manual and I'm about to purchase the service manual on a USB drive - just need to verify they send me the correct one for my s/n. Good advice Nige, I'll incorporate that into my next service interval.
