How to Disassemble Lean System Without Damaging Components

Disassembling a lean system isn’t something you just wing. You need a plan. Start by rounding up your tools—nothing fancy, just the basics. A set of hex keys (those L-shaped wrenches are a must for aluminum profile joints), a rubber mallet (for gentle tapping—no sledgehammers!), a Phillips and flathead screwdriver, some zip ties, and a marker. Oh, and don’t forget gloves! Those aluminum edges can be sharp, and you don’t want to end up with a cut halfway through.

Next, safety first. If your system has any electrical components—like lights on a workbench or motors for conveyor belts—unplug them. No exceptions. Then, clear the area around the system. You don’t want tripping over boxes or having tools roll away while you’re mid-disassembly. Lay down a clean tarp or some cardboard too; it’ll protect both your components and the floor from scratches.

Finally, label everything. Grab your marker and some masking tape, and tag components with where they go: "Left side of Workbench A," "Roller track section 2 (between Station 3 and 4)," you get the idea. It might feel tedious now, but when you’re staring at a pile of parts later, you’ll be glad you did.

Think of your lean system like a puzzle—you don’t start with the edges; you start with the small pieces. So begin by removing all the detachable accessories. We’re talking about things like bins, tool hooks, caster wheels (those swivel ones under workbenches), and any loose panels. These are usually held on with simple screws or clips, so they should come off quickly.

Take caster wheels, for example. Most are attached to the workbench legs with bolts. Grab your wrench, loosen them up, and set them aside. But here’s a heads-up: if the system has been in place for a while, those bolts might be rusted or tight. Spray a little lubricant (WD-40 works great) and let it sit for a minute if you’re struggling. No need to force it—stripping a bolt is a nightmare you can avoid.

Next, move on to smaller components like swivel roller balls. You’ll find these on flow racks or the edges of workbenches, helping parts glide smoothly. They’re often held in place with tiny clips or screws. Use a small screwdriver to gently pop them out, and ｄｒｏｐ them into a labeled baggie. Those little balls are easy to lose, so don’t just toss them in a pile!

Now we’re getting to the structure: the lean pipes and aluminum profiles that form the skeleton of your system. This is where patience really counts. Remember those photos you took? Now’s the time to reference them. Start by identifying the main joints—those are the connection points where pipes or profiles meet. For lean pipe systems, you’ll usually see metal or plastic joints (like 90° fixed joints or 180° swivel joints). For aluminum profiles, it’s all about those T-slot connectors and angle brackets.

Let’s start with lean pipes. Most joints are secured with set screws—small screws that tighten against the pipe to hold it in place. Grab your hex key, and turn those screws counterclockwise to loosen them. Go slow here—if you rush, you might strip the screw head. Once the set screw is loose, wiggle the joint gently to free it from the pipe. If it’s stuck (thanks to years of holding weight), tap the joint lightly with your rubber mallet. Avoid hitting the pipe itself—lean pipes are sturdy, but they can bend if you whack them too hard.

Aluminum profiles are a bit different. They use T-slot nuts and bolts that slide into the grooves of the profile. To remove a bracket, you’ll need to loosen the bolt until the nut slides out of the slot. But here’s a trick: hold the bracket in place with one hand while loosening the bolt with the other. If you let go, the nut might fall into the profile, and fishing it out is a pain. Ask me how I know.

With the smaller parts and frame sections removed, you’ll be left with the larger components: workbenches, roller tracks, and maybe even conveyor systems. Let’s start with workbenches—they’re usually the heaviest, so you might need a second pair of hands here.

Most lean workbenches have a tabletop (often wood, plastic, or aluminum) attached to a frame of lean pipes or aluminum profiles. First, remove the tabletop. It might be screwed into the frame from underneath—flip the bench gently (with help!) to access the screws, or lie on the floor and reach up. Once the top is off, disassemble the frame the same way you did earlier: remove joints, label pipes/profiles, and set them aside.

Now for roller tracks—the ones with all those little wheels that make parts glide. These can be tricky because they’re made of multiple sections connected by brackets. Start by removing any end stops or side guides (those plastic or aluminum pieces that keep parts from falling off). Then, look for the connectors that hold track sections together—they might be clips, bolts, or special placon mounts (those little brackets that attach to aluminum profiles). Loosen those, and separate the sections one by one.

Here’s a crucial part: handle the roller wheels with care! If you’re dealing with swivel roller balls (the small, 0.5 inch or 1 inch ones), don’t stack the tracks or ｄｒｏｐ them. Those balls can pop out of their sockets, and replacing them is a hassle. Instead, lay track sections flat on your tarp, or wrap them in bubble wrap if you need to move them.

Not all components are created equal—some need extra love. Let’s talk about ESD workbenches and stations first. These are designed to prevent static electricity from damaging sensitive electronics, so their surfaces and components are often coated with special materials. When disassembling, avoid using abrasive tools (like steel wool) that could scratch the ESD coating. Also, store ESD parts separately from regular components—maybe in a labeled bin with a note: "ESD—Handle with Gloves Only."

Stainless steel parts are another category to watch. They’re resistant to rust, but if you scratch them, that resistance drops. Wipe them down with a dry cloth before storing, and avoid stacking heavy parts on top of them. Oh, and if you’re disassembling in a humid area, toss a silica gel packet into their storage bin to absorb moisture.

Finally, small precision parts—like the bush adapters, anti-slip leveling feet, or the internal rotary aluminum joints. These tiny pieces are easy to misplace, so put them in sealable plastic bags as soon as you remove them. Label each bag with what’s inside: "10x M10 Rubber Leveling Feet (Workbench B)" or "5x 45° Aluminum Pipe Joints (Left Frame)." I like to use sandwich bags—they’re cheap, transparent, and easy to write on.

Even with the best prep, things can go wrong. Here’s how to handle the most common issues:

You’re almost done! Now that everything’s disassembled, it’s time to clean and store the components. Wipe down each part with a damp cloth to remove dust, grease, or debris—especially important for aluminum profiles and lean pipes, which can collect grime over time. For stainless steel parts, a quick wipe with a mild soap solution (and then drying thoroughly) will keep them shiny and rust-free.

Sort components into categories: "Lean Pipes and Joints," "Aluminum Profiles," "Workbench Parts," "Roller Tracks and Wheels," etc. Use separate bins or boxes for each category, and label the boxes clearly. If you’re storing parts long-term, invest in plastic storage bins with lids to keep out dust and moisture.
