This video is a job we did to repair & replace a broken trunnion bearing end on a Push Arm for a Caterpillar D8T Bulldozer. The trunnion end has a crack all the way through it and we need to replace it. This shows the step by step process to remove the cracked trunnion end using air arc gouging and prep the side arm before fitting and mig welding on the new trunnion end.

In this video we are using:
Lincoln Electric DC-400 Welder
WIA 500i Weldmatic welder
