CAT D10 Dozer Cylinder Rebuild | Part 3 | Making the New Rod

This video is part 3 of rebuilding a Caterpillar D10R dozer blade tilt hydraulic cylinder. In this episode we are replacing the damaged cylinder rod. The rod has scratching and the chrome is damaged so needs to be replaced. We start with pressing out the old bushing to check if the eye is damaged or not. Then the rod is setup in the lathe and we machine and part the eye off the cylinder rod. We machine up the new cylinder rod using 4" inch diameter induction hardened chrome bar. We need to machine both ends of the cylinder rod, the first end we are machining for the piston and cutting the external thread for the nut. The other end of the rod we also machine to fit the original rod eye, which is then MIG welded with metal cored wire before machining down the welds to complete.
