    JD 35G excavator thump only works in one direction

    Moosehead101: This is the diagnostic procedure that came up from Green Tractor Talk for your model excavator. I have no idea if this is exactly correct. If you don't have one it might be worth purchasing a JD service manual for this machine before getting deeper into the issue. There are also...

    JD 35G excavator thump only works in one direction

    Hey Moosehead 101: I did a quick AI search on this machine for you. The sources were: Green Tractor Talk, Contractor Talk, Boom & Bucket and unknown generic sources on the web. The troubleshooting described here may help your discovery process. It appears to be a common issue and thus a lot of...

    Tb125 overheating issue

    Very cool diagnostics. Maybe you could run that infrared on the intake hose on the top and lower hose on the bottom and see if there is a drastic heat difference--which then might point to a water pump issue. These sensors, I believe, are thermistors (meaning the ohms resistance drops as the...

    Maintenance: Tricks of the trade

    It looks like you could do surgery with those clean tools. A very good reminder for me to get my act together and do a better job organizing and keeping tools in good condition. Your post reminds me of a project I was on back in the late 1970's. I was with a trouble shooting group trying to...

    Maintenance: Tricks of the trade

    I recently had a 50 hour service on my new Kubota LX3310. The mobile mechanic came to my property to change engine oil, engine oil filter, transmission oil filters, and the hydraulic oil filter (this was part of the purchase agreement). I asked how to he would change the hydraulic oil filter (on...

    Kx040-4 code 065

    Congratulations! I guess that Kubota mechanic's instincts were right. Likely a broken wire. I'm constantly fighting mice encroachment in my excavator (parked outside). I've tried just about everything to keep them out of the machine (and same with our cars parked outside). Sooner or later I know...

    Tb125 overheating issue

    Have you checked fan belt tension when the machine is hot? It could also be a worn/faulty water pump (assuming you're using a good quality coolant). The oil cooler could be clogged too or providing restricted flow. Have you changed the oil cooler filter? I believe there is a a way to test oil...

    Kx040-4 code 065

    Hey davisgravel: One last thought. When I spoke with my Kubota mechanic he said, "Buy a diagnostic tool. You don't need one with all of the bells and whistles that I have (several thousands of dollars) because you're only going to use it on one specific machine." I did a search and found an...

    Kx040-4 code 065

    Since your not the OP and you've inserted yourself here I suggest you read the thread carefully. Yes, I did an AI search. I did check it against the WSM for Kubota excavators that I possess. The manual is not real helpful. The AI input scans anything available online (in this case WSM material...

    Kx040-4 code 065

    I just talked with my mechanic. Here are his general comments: He has never had to replace a MAF sensor. More than likely mice have chewed through a wire somewhere so the ECM isn't getting the correct signal. Kubota connectors are generally very good--so it's unlikely that it's a connector not...

    Kx040-4 code 065

    I have a conversation scheduled tomorrow afternoon (Monday) with a 25 year Kubota mechanic regarding installing a case drain on my U55-4. I've already given him a heads up that I'd like to pick his brain on your situation. I'll pass the notes from that conversation on to you tomorrow. Maybe he...

    Kx040-4 code 065

    So, I personally would: 1) look for corroded wiring or broken wires in that circuit, 2) test to see if the sensor is working correctly, 3) check for any air leaks between the turbocharger and the intake manifold which would lead to a low boost pressure... and 4) do a hard reset of the ECM and...

    Kx040-4 code 065

    Yes. No one had responded to your thread. I thought this quick AI search might help your effort. The limp mode is ECM triggered to protect the engine/hydraulic systems when a sensor error pops up. I haven't gone through the WSM (Kubota mechanic's workshop manual as of yet. Which I have for...

    Kx040-4 code 065

    The Kubota KX040-4 error code 065 generally indicates a hydraulic pressure sensor malfunction or a related wiring issue. It is often accompanied by engine system errors (Limp Mode) caused by issues in the aftertreatment system, specifically related to DPF (Diesel Particulate Filter) pressure or...

    Cat 310 Case Drain Issue?

    I think it's good practice to relieve all pressure on lines each time you quit operating. That may solve your leakage issue if you're not already doing it. On my machine (Kubota) here is the general procedure. I don't have a grapple, just buckets and a brush mower...
