I made my own by sacrificing the old screw to tilt brace. I don't think Cat ever had a tilt option on the 8u&9u blades.Welded the top few inches with the ball part of old brace to the shaft from the ram. I used a ram that was lying around. But if you need to buy one check Surplus Center in Neb.
Size of ram will depend on GPM and pressure of the hydraulics used to power it.
This is a pic of the tilt cylinder from the D4 40A I have listed for sale on this forum, it does not leak. I sprayed weed killer before taking pic. If I can't sell the dozer as a whole. I will scrap the dozer out.![]()
