    L3430 Run With No Oil

    I have some experience with blown d1703s Owned a l3430 that ran out of oil similar to you but it was through the oil filter after a puncture. The surprise was the rod bearing were not that bad, what died was the cam bearings to the point the camshaft gear broke off. What I strongly recommend...

    D1703 no compression in 2 out of 3 cylinders.

    I have a genset here with no compression on #2 and #3 cylinders. #1 shows a excellent 580PSI (Not a very accurate gauge either, so I am sure its slightly lower) I do not know the history of the genset, but it did come from a scheduled maintenance environment so it was not heavily neglected...

    L5030 injector pump leak

    The sealant should be between the jetcock assembly and the banjo bolt leading into the injection pump.

    Compression Testing

    It's no worries. Kubota E-TVCS actually stands for Three Vortex Combustion System, which references the pre combustion chamber. No idea where they would list Direct injection. Many of the IDI engines are offered as DI alternatives (V2403, V2203, V2003, etc.) and they always have a DI in the...

    Compression Testing

    Uhm.. That is not possible. What engine do you own that uses standard injectors on a direct injected engine? Even Tier 2+ V2203 use a pencil style injector (a bit fatter pencil), and that is clamp down, not screw in. They require the length as a DI engine injector injects in the middle of the...

    Compression Testing

    This is specific to Kubota's. All IDI Kubota's have screw in injectors and a short glow plug that meets in a pre combustion chamber. Direct Injection Kubota use a long pencil style injector that is bolted down with a bracket, and have a long glow plug as they both meet in the combustion chamber...

    Compression Testing

    Anything that is Direct Injection uses pencil injectors, Anything that is IDI uses standard Kubota injectors.

    L5030 injector pump leak

    Let's just ignore the pump guys suggestions for 5 minutes, because all he sees is a failed o-ring and it was really nice of him to find you the part numbers for those, but I have seen many low hour and high hour kubota's and I have never seen those fail. All they ever see is mechanical pump...

    L5030 injector pump leak

    From overheating. Where is it leaking externally? Can you take a photo? If it is leaking at one of the 4 injector outlets, it would be pulsed. So when idling you would see it squirt and that cylinder would not run correctly. Odds are you leaking from the banjo fuel inlet which has two...

    L5030 injector pump leak

    What makes you think it is leaking diesel? Is it leaking externally or do you have milky oil? If its milky oil I would confirm if the tractor does not have a cracked head, they usually crack on the #4 piston to coolant passage.

    L3700SU won't turn over. Please help!!

    You most definitely have a bad ground or positive cable heading to the starter. You may also have a bad safety switch. The click you are hearing from your start attempt is most likely a relay or the stop solenoid pulling. It is unlikely it the starter solenoid, because typically these will...

    First tractor purchase advice

    Tier 4 is a death trap. I have no problem with emissions control equipment on vehicles that are constantly in use. Such as trucks, construction equipment, etc. But if you take into consideration the time that a average compact tractor owner uses their machines for annually (hour wise), this is...

    First tractor purchase advice

    I might get torched for offering this educated piece of advice. If you can, purchase a 40 series tractor. Something along the lines of a L5040. You get the benefits of the new HST transmission with stall guard, etc. and the new style cab and tractor, but you do away with DPF filters, common...

    2002 3710 GST (600hrs) Fair Price?

    I think you should be in the neighbourhood of $10-12,000 without a loader and without the additional implements. You can ask for more, but its unrealistic you will get it This is assuming its a 4x4 tractor.

    Tractor dies after a few minutes of running

    This is a good idea as well. It does have dedicated breather lines, and it is a return system, but very possible especially with a electric fuel pump

    Tractor dies after a few minutes of running

    I think many of your have never actually experienced fuel jelling, and I really think its a BAD idea to encourage the original poster to just randomly pour things in his gas tanks such as Algaecide or Power Service. This is NEVER recommended unless you are filling a Known size tank that you can...

    Glow plug wires/removal question

    Some of the smaller Kubota Tractors I would almost always recommend removing the intake manifold if you are going to be removing glow plugs as the clearances are typically tight. Yes, absolutely run the engine to temperature before removal.

    Disappearing - Reapppearing Hydraulic Fluid

    This is very normal as there are many gears and bearings the fluid lubricates and sticks to, its exact purpose. This is the exact same reason why you are always told to check oil level or fluid levels after the tractor or any vehicle for that matter has cooled. Some vehicles actually have...

    Weird... S2200 injection pump on M4500DT S2600 engine?

    Typically there is not a physical difference. Because the fuelling is also your throttle the position on the rack and injection timing are the only difference. Most likely on a S2600 there will be less shims under the pump allowing for a longer/larger stroke on the fuel camshaft. Typically...
