Replacing Damaged Hydraulic Cylinder Rod for Caterpillar D10 Bulldozer - Part 2

Watch the machining process for replacing a damaged hydraulic cylinder rod on a Caterpillar D10 Bulldozer ripper lift cylinder in this 28-minute video. Follow along as a 3 1/4" diameter induction hardened chrome bar is transformed into a new cylinder rod using a TM-26120G lathe. Observe the precise steps of machining one end for the piston and nut, including turning down the OD and cutting external threads. See the other end prepared for welding the rod eye, with a bevel machined and hole drilled for the eye spigot. Witness the final step of attaching and metal core welding the rod eye onto the new rod. Learn about various machining techniques, tool changes, and specific processes like relief groove cutting, chamfering, and drilling. Gain insights into real-life machining work for heavy machinery in the earthmoving, mining, and civil construction industries.
