Session 7 focuses on the parts of a hydraulic system that don’t always get much attention—until something leaks, fails, or doesn’t fit. BJ Wagner walks through hoses, tubing, fittings, and reservoirs, showing how these “in-between” components play a major role in system reliability. From proper sizing and identification to installation and selection, the session highlights how small details in fluid conveyance can make a big difference in performance (and headaches avoided).

Session 6 is where hydraulics finally gets to do what it was built for—move things. Cylinders push, motors spin, and suddenly all that pressure and flow starts turning into real work (instead of just numbers on a schematic). BJ Wagner walks through how actuators behave, why speed and force are always negotiating with each other, and how changing one setting can quietly affect everything else. From telescopic cylinders doing their staged “one thing at a time” routine to accumulators storing energy like a loaded spring, this session highlights how motion actually happens—and what can go wrong if it’s not controlled.

Session 5 is where everything starts coming together—valves stop being individual components and start acting like a full team (for better or worse). BJ walks through how different valve types interact in real circuits, how flow, pressure, and direction all influence each other, and why small setup details can have a big impact on performance. From synchronized actuators to load sense systems and accumulator circuits, this session highlights what actually happens when a system is running—not just how it’s supposed to work on paper.

Session 4 shifts into valves—the components that control pressure, direction, and flow (basically, the ones that decide if your system works… or just sits there). BJ breaks down the different types, how they function, and why small details like pressure settings and flow control can make a big difference in performance.

Session 3 is all about hydraulic pumps—the heart of the system and occasionally the reason your day gets complicated. BJ walks through pump types, how they actually move fluid, and why some are overachievers while others are just along for the ride. We also cover cavitation and aeration (aka the “your pump sounds terrible” phase), take a look inside gear, vane, and piston pumps, and talk about efficiency, pressure limits, and how not to accidentally shorten your pump’s lifespan. It’s part theory, part real-world reality—because in hydraulics, things always sound fine… until they don’t 😄
