Repair DAMAGED Hydraulic Cylinder for CAT 16H Motor Grader | Machining & Welding

This video is a job we did to repair a damaged hydraulic cylinder for a Caterpillar 16H Motor Grader articulating cylinder. The piston, bolt and nut are stuck inside the cylinder barrel and caused a bit of damage to the cylinder barrel and rod, so we need to replace the barrel and repair the threads on the rod. First we cut off the oil port on the cylinder barrel, then set up in our lathe and machine off the weld to remove the barrel end. We then make the new barrel which includes drilling the oil port, machining for weld prep, cutting an internal thread and welding the oil port and end cap on to the barrel. We finish off the repair by hand tapping the internal thread on the cylinder rod. In this video we are using: - BM-63VE Milling machine - TM-26120G Centre Lathe - WIA 500i Weldmatic welder Join our channel: We upload new videos every Friday at 5pm AEST!
