Watch a comprehensive 47-minute workshop tutorial demonstrating the complete restoration of a damaged CAT 657 Scraper cylinder rod with a completely destroyed eye assembly. Learn the step-by-step process of removing the damaged eye using an oxy torch, then follow along as the rod is set up in a lathe to machine a new spigot while navigating the challenges of interrupted cuts that require careful tool adjustments and controlled passes. Observe the fabrication of a replacement eye from 90mm Bisalloy 80 high tensile plate using a milling machine to drill the spigot hole, create spot drilling for live centre positioning, and machine the grease port with proper drilling and tapping techniques. Discover the critical weld preparation procedures before the eye is tacked and fully welded using rotators with CIG Verticor wire, followed by precision machining of the eye bore to final specifications. Master the techniques for cutting snap ring grooves, machining reliefs and chamfers, and applying the final paint finish to restore the component to original specifications with correct geometry and clean bores ready for heavy earthmoving applications.
