    Parts arrived, tool fabricated, everything assembled and the beast has been working hard in very hot weather. We have finished in The Pilbara for this year as it is now too bloody hot and the wet part of the year is here. We moved back to the Northern Goldfields where it only gets to 42 celcius...

    We have had our JD running well for a couple of years now after my last posting here but all good things must come to an end. Two days ago I was moving it to another area on the access track and got a sniff of what seemed to be an electrics cooking. I went around the back of the machine and...

    Clearing history

    Not hiding anything, just that where I live and work internet is often difficult and anything that uses up space will slow it down even more. Oftentimes I have to climb up a hill and hope to get enough phone signal to make the world come to my laptop. Also if I am looking for something I don't...

    Clearing history

    If you are using chrome there is an addon called "click and clean" that allows you to clear all the history etc when you use it to close chrome. Otherwise just use Firefox and configure it to clear history and cookies when you exit firefox

    DB2, I used to work on a lot of japanese imports in New Zealand. Nissan diesels like the TD27, TD28 and TD42 often had a tiny filter inside the injector pump. You had to remove the fuel inlet banjo and fish around for them. It was amazing how much crud had made it through the prefilter and...

    SCV was replaced and all appears to be well, apart from the bank balance. $630 plus tax, plus freight. All up almost $800 ozzie dollars. The beast sounds different when it starts and is better able to handle loading up the blade. Greatly appreciate all the help.

    Update. Changed pump and primary filter while I was at it. We found the box of bits that came with the machine and there were a dozen primary filters in it. Perhaps this is an ongoing problem. So I got my son to blow the line back to the tank when he changed the filter. The machine worked ok...

    OK I am back on the case. Was sent to another site for a while and borrowed a guage while there. 0-100 psi which is too big but it was available. Barely moved the needle so I think the initial diagnosis of pump pressure has some serious merit. I rang the Hitachi parts people (agents or JD here...

    I got back to the grader or a few minutes today. Cleaned and rechecked all the connectors, checked the wiring or cracks and did all the basics again. Pressure sensor connection had the tiniest bit of corrosion so cleaned and resealed. vigorously wobbled all connectors and rebled the system up...

    I have had to go to another site or a few days so I will check all those when i get back. I really appreciate the efort you have put into this as it makes my job so much easier. When I return I will get an assistant and do the wire wiggle and all the other things as well. The 418 code hasn't...

    SCV is about 3 inches all up so I guess it is the newer one. Appears to be fully functional with no sticking apparent. It engages for a few seconds when first powered up and then disengages. I activated it several times and it appears to be a smooth operation with no notching felt. Re assemble...

    I changed the filters. Primary was dirty with gunge, secondary was clean. I tapped them both out onto clean rags after draining on other rags. Primary had some dirt in it and definitely needed changing. Secondary showed no visible sign of any contamination. Checked fuel output at the pressure...
