    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...
