Overview
Pete walks through a complete hydraulic cylinder rebuild on a Kubota B21 unit, covering leak diagnosis (wear, rod scratches, bent rod), disassembly with common tools like a pipe wrench, bore inspection, and step-by-step seal replacement with clear guidance on seal orientation. It's a practical, hands-on how-to that goes deeper than most walkarounds; owners comfortable with basic mechanical work will get the most from it.
