CASE S SC D DC LA 400 500 600 700 730 800 830 900 930 1030 Tractor Dual Valve Kit. This kit seals the vertical levers that go into the dual valve to work the spools. Will also work on the single valve unit, but you will have parts left over. This is a real nice kit, really complete, & I’m surprised CASE still offers this kit. Please contact us for current pricing.
