We’re going to tackle this complex part and show you the step-by-step repair of a broken double acting telescopic cylinder for a Cat 657 Scraper Ejector cylinder. Join us as we take you through the entire process, from removing the damaged end to machining a brand new inner tube. We'll start by cutting and removing the broken section. Next, we'll head over to the lathe to machine out the weld joint and use some heat to help us separate the rod eye and inner tube from the outer cylinder. The old inner tube won't be salvageable, so we'll machine a brand new one to fit perfectly. But that's not all! We'll also show you how to press the new tube into shape and align everything before welding it securely to the rod eye. Once the new inner tube is in place, we'll prepare the outer tube for welding and carefully reassemble the entire part. Finally, we'll machine down the welds for a clean finish, getting this component ready for re-chroming. Double-acting hydraulic cylinders do have a complexity that can lead to a few issues, even a minor leak can compromise the precision of how it works, so join us we bring this broken one back to life!
