    komatsu Dozer Main Control valve

    Welder Dave, we checked with several machine shops and was told it would be impossible to machine one of these. These spool valves also has a hole inside of them. I guess they are molded in the factory. And I was told this is a 1998 year model machine. Good news is I have a used control...

    komatsu Dozer Main Control valve

    Mr. Ellis if you click on this link you can go to my other post. I ended up taking mine off to rebuild it and in hindsight I should have left well enough along. I ended up breaking a spool valve and they no longer sell them. You will not find a used one. Nor will you find a used entire...

    komatsu Dozer Main Control valve

    Thanks Dave. Thats good news. Its going to be a happy new year after all. I dont use it that much, so it sits a bit, so maybe thats why its stiff, but do i need to pull it out to replace what ever (orings or seals) that are under those allen wrench screw caps? its got a pretty good leak on...
