This CAT 140 M Grader NEEDS Repair, Part 1, Blade Skin Trunnion Balls

This 140M Grader is 14 years old and needs a lot of work and repairs done to it. This is a Caterpillar 140M Motor Grader and its used for grading and trimming flat surfaces to prep for roads and infrastructure. In this Part 1 video we start with fitting and installing a new blade skin because the original blade is badly worn away and needs to be protected. We then move on to replacing the trunnion ball mounts that attach the blade lift cylinders to the Aframe because those are also worn out. We remove the old mounts by using air arc gouging before fitting and welding on the new mounts. We complete the job by making everything look nice with some grinding and paint. Watch Part 2 here: and see how we disassemble and install new seal kits on a lot of the hydraulic cylinders In this video we are using: UniMig Razorcut 45 Plasma Cutter Lincoln Electric DC400 Welder Lincoln LN25 Pro Wire Feeder WIA 500i Weldmatic welder Join our chann
