Repair DAMAGED Mining Truck Cylinder Barrel | Part 2 | Machining & Honing

Now the welding has cooled let’s get this job finished! This video is part 2 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. In this Part 2 we show step by step to complete the replacement of this cylinder barrel. We counter bore the weld on the ID of the barrel before machining the entire OD of the barrel down to size. We also use our 1960s Delapena vertical honing machine to hone the ID of the barrel before fitting and welding the barrel end on to complete the job.
