    For that age of engine .. probably just as quick to go main dealer. Does it have a Kubota number on it ?

    Kubota have sorted their shit out regards parts pricing, so I was thinking they might be better than HM, but you would need to know the engine type. The usual problem is that the Maker (hitachi) usually force other major parts suppliers to remove any branding or numbers that make any sense for after market bits, so you usually have to go through the main dealer unless you do a lot of detective work.. I had a lot of this with Mitsubishi engines in early Volvo minis

    What actually is the problem with your injectors? They are actually quite easy to clean on these engines, as long as the nozzles and valves are not to damaged they work fine.

    That's part of problem, couldn't find any info on engine Muz

    Mick, its a bit of a strange one. Occasionaly the machine runs very smokey, started all of a sudden last week. Smoke is blue/grey which made me think it was burning oil. An engineer pal reckoned it did smell like unburned diesel despite the colour. I cleaned a lot of scum out fuel filters and though it was sorted but then started smoking again after 2 days.

    We checked injectors and two weren't atomising atall, pressures were ok though. Compression test was fine so no problems there.

    Have you taken the fuel pipe off to see a good flow going into the injection pump ? diesel should be jumping out of the pipe

    Not the first time I've had an obstruction like a flake of paint from a diesel drum blocking a banjo connector

    *edit* after checking all the other filters and primer pump

    used to have a Cummins 290, in a 45t Grove that'd smoke like a bitch ..... if the fuel filter got any water in it - passed fuel ok, but if the filter got 'soggy' .... same sort of symptom - try a new filter and check any water traps for H2O.

    Had a 240 in a 30 tonner, at the same time, that didn't do it ....... Go figure?
    If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!
