Repair DAMAGED Mining Truck Cylinder Barrel | Part 1 | Machining & Welding

You won’t believe what damaged the inside of this barrel! This video is part 1 of a job to repair a damaged hydraulic cylinder barrel from a mining truck. This is the hoist cylinder barrel off a Caterpillar 785 Haul Truck, the cylinder helps to lift and lower the body when dumping out the payload. Something has failed and caused big scratches and gouging on inside of the barrel, so we need to replace the main part of the barrel! In this Part 1 we show step by step to disassemble the damaged barrel by machining off the barrel end and the head flange. We also fit and weld the head flange to the new barrel using spray transfer MIG welding.
