Making a New CAT D11R Dozer Cylinder Rod - Machining & Welding

Explore the step-by-step process of manufacturing a new hydraulic cylinder rod for a Caterpillar D11R Dozer blade lift cylinder in this comprehensive 48-minute video. Learn how to machine and weld a replacement rod, starting with removing the damaged eye and bearing. Follow along as a 4-inch diameter induction hardened chrome bar is transformed into a new cylinder rod, including machining both ends, cutting external threads, and preparing for welding. Observe the welding process using metal cored wire and the subsequent machining to maintain a standard appearance. Witness the cryo freezing and shrink fitting of a new bushing using liquid nitrogen. Gain insights into the use of various equipment, including a TM-26120G Centre Lathe, WIA 500i Weldmatic welder, and HMP-150T Hydraulic press. Discover the intricacies of manual machining, hydraulic repairs, and heavy fabrication for earth moving, mining, and civil construction industries.
