    you will require the following new replacement parts.
    the ARM 2 spool supercedes, including a new lower spool cap and detent plug.
    also the 2 unloading valves supercede part numbers and should also be replaced.
    part numbers as follows along with the recommended ordering status.
    1 -> LC30V00034R220, ARM 2 SPOOL, must order on a unit down
    1 -> LC30V00034S979, SPOOL CAP, LWR, must order on a unit down
    1 -> LC30V00034S981, SPOOL CAP, LWR, DETENT PLUG, must order on a unit down
    2 -> YN30V00120F2, VALVE, UNLOADING, order on an air
    1 -> ZD12P00800, o-ring, likely stocked
    1 -> ZD12G04000, o-ring, likely stocked
    1 -> ZD12G05000, o-ring, likely stocked

    also, i recommend you check the cpu version in your machine computer.
    the latest greatest version is 6.00
    depress the buzzer stop switch on your monitor display and while holding turn the ignition switch to " ON " position. do NOT start the engine.
    screen no. 1 should display and read the version.
    depending on your version, if older you will require a kobelco dealer to download the newer version. if not, ship the computer to me and i can bench load the version.
    afterwards, the machine will require setting up and this can be done over the phone.
    ensuring that all the hyd sensors readouts are as they should, the engine rpm's within specs, as well as all the hyd pressures too.
    this may involve un-tweaking some screen settings to do so.
    then re-tweaking after.

    if your machine has only the one HINO fuel filter,
    there is an optional dual fuel filter assembly field install kit that is available for ordering.
    an improved filtration system. i do highly recommend that you consider purchasing it. it will better your filtration of the fuel system and prevent possible problems down the road.
    the price of this kit compared to the high costs involved if you were to run into problems in the fuel system is in my mind cheap insurance!
    kit part# LC32T00017F1, can be ordered on a stock order
    new replacement fuel filters used in the kit
    - VH23390E0020, 2 um fuel filter
    - LS21P01013R100, 7 um fuel filter
    be sure to also have spares brought in on a stock order as well.
    Thank you sir, ill run it by the dealer here and see what they say. The tech line never mentioned anything like this. Was this the reason for the changup in the spool?

    been looking at some new buckets for my '98 sk130lc. are they the same as the buckets for the 120s? there are quite a few around, but they all say 120 or 150 on them, i assume one of these should work on my 130??

    (the track question from the 120 to a 130 made me think )

    thanks

    hi eianewb,
    the sk120 buckets differ from the sk130 buckets.
    i do believe they will pin on but the spread or distance between the centre to centre of the pins are not the same.
    if you have a hyd pin grabber or such...it may not work for you.
    you will also lose out on some bucket breakout forces.

    I have a sk75ur that is having fuel problems. It seems as if the machine unprimes itself every time I shut it down. No visible fuel leaks. the fuel all seems to bleed back to the tank. I hope I am using this forum properly. This is my first time.

    hi picklehead,
    it sounds as though you will need to replace your fuel lift pump and it would not hurt to also replace the fuel overflow (fuel control) valve.
    also, be aware of those inline fuel screens.
    if your engine is a Mitsubishi the input fuel hose attached by a fuel banjo bolt to the fuel lift pump will consist of a nylon mesh fuel screen screws into the bolt.
    pinch line, remove bolt, unscrew screen and clean.
    if damaged replace.
    also, if the engine is an Isuzu there will be a second inline fuel screen located inside the bolt (same deal) affixing the fuel hose that leads from the fuel tank to the inlet port of the fuel water seperator filter head.
    cheers!

    Not sure if there's any problem or not, but SK290LC Dyn Ac. seems to take quite a while to warm up on 45 degree mornings. Scared to think how bad it might be in really cold weather!

    sk75ur

    THANKS!!!
    It is a Isuzu. Where is a good place to buy a lift pump? I am going to fill the tank completely up with fuel, and I suspect gravity will push the fuel to the filter. That should confirm the lift pump failure. I will clean the screens first.


    Thanks again Mr. Kobelco

    there are a few things that may contribute to this.
    the auto-warmup is dependent upon certain conditions to function properly.

    please have your serial number at that time.

    hi picklehead,
    you can purchase the fuel lift pump from us.
    i will need all your fuel injection pump numbers record off the tag.
    even numbers on the lift pump itself.
    you might even be able to get from an authorised fuel inj pump overhaul shop.
    i do stock these and will likely have it on our shelf.
    e-mail numbers and your contact info to hf_hydraulics@hotmail.com

    hi picklehead,
    yes we can get all your parts needs. the body panels might be expensive new but there are other shopping avenues. such as H&R Construction parts.
    i would suggest quoting on price and avail on new and H&R to explore all your options.
    lights, no problem we stock them on our shelf.
