How I Restored a Caterpillar Hub’s Damaged Collar with Lathe-Machined Threads






In this video, I show the step-by-step process of restoring a damaged collar on a Caterpillar hub using a lathe. The collar was worn and stripped, but with precise lathe machining, I was able to cut new threads and bring it back to working condition. This detailed repair involves measuring, turning, threading, and refitting—all captured clearly to help anyone interested in mechanical repairs or lathe work. Whether you’re a machinist, mechanic, or DIY enthusiast, you’ll find valuable techniques and insights in this restoration project.
