Repair TWO Damaged CAT 777 Dump Truck suspension parts | Line boring & Welding

This video is a job we had to repair two damaged Caterpillar 777 Dump Truck Suspension parts. These are the rear strut suspension cylinder barrels on the dump truck and the truck has been scrapped for parts. On these parts the internal bores are worn out and the outside of the eyes have been damaged after being gouged or oxy cut off the truck. To get the job done we are using our Sir Meccanica WS2 portable line boring & bore welding machine. First we need to repair the outside of the barrel eyes by grinding out the damaged material, welding up and using our 9” inch angle grinder to grind back to shape. The internal bores also need repairing as they are worn out so we get on to setting up and tack welding on the bearing mounts for positioning the line boring machine. We need to line bore out the eye material before bore welding to build up new material and then boring out to spec. The eye is then ready for facing, cutting the chamfers and snap ring grooves. The repair is completed by drilling in the holes for the grease port and cleaning up the surfaces.

In this video we are using:
- Makita 2400W 9” inch Angle Grinder
- WIA Weldmatic 500i Welder
- Sir Meccanica WS2 Portable line boring machine
