Line boring and Bore welding Caterpillar 775 Truck rear strut rod | Sir Meccanica WS2

In this video we are line boring and bore welding to repair a Caterpillar 775 truck rear strut rod that had a bearing fail and damage the rod eye. We are using our Sir Meccanica WS2 portable in-line boring and bore welding machine. First is setting up and tack welding on the bearing mounts for positioning the line boring machine. We need to line bore out the damaged eye material before bore welding to build up new material before boring out to spec. We also cut the internal snap ring grooves using a boring and facing head from a milling machine that was adapted for cutting snap ring grooves. The repair is completed for our customer by drilling in the grease port and cleaning up the strut rod eye surfaces.
