Disassembly of the Xiaomi M365 is often a necessity when you need to replace the camera, eliminate the backlash of the steering column or conduct a deep cleaning of dust and moisture. Despite the minimalist appearance, the design of the device is designed so that access to the main components requires the serial dismantling of several layers of protection. It is important to understand that opening the case can affect warranty obligations, so all actions you perform at your own risk.
Before you start any work, you need to prepare a workspace with good lighting and free space. You will need not only a standard set of tools, but also specific screwdrivers, since Chinese engineers use screws with custom hats. The main difficulty in disassembling the M365 is hidden screws under decorative plugs and rubber seals, which are easy to damage if you carelessly handle.
In this article, we will take a closer look at the process of dismantling the deck, steering rack and motor wheel. You will learn how to properly disconnect high-voltage cables without damaging the contacts, and what nuances exist when removing the controller board. Following the instructions will help avoid common mistakes that often lead to plastic breakage or short circuit.
Preparation of tools and security measures
A good disassembly is impossible without the right tools. The standard home kit may not work, as the screws in the Xiaomi M365 are often tightened with a thread lock. You will definitely need a set of bits that includes T20 (star) and PH2 (cross).
The first rule of safety is to shut down the power completely. Before you unscrew the first screw, you need to make sure that the scooter is turned off. Moreover, to work with the insides, it is recommended to discharge the battery to a minimum or disconnect the power connector immediately after removing the top deck cover, this will reduce the risk of short circuit when the contacts are accidentally touched by the tool.
- 🔧 A set of screwdrivers with bats T20, PH2 flat-slit.
- 🔋 Tweezers with dielectric coating for working with small parts.
- 🧤 Dielectric gloves to protect against residual voltage.
- 💡 Lantern or lamp for illumination of the interior cavities of the deck.
⚠️ Warning: Never start disassembling if the scooter has just been in service and the battery is heated.Let the device cool to room temperature to avoid thermal expansion of components and possible damage to the insulation.
Organize the space so that the screws are not lost. It is recommended to use a magnetic mat or containers with signatures for each stage of disassembly. screws of different lengths, twisted in the wrong holes, can damage the plastic case or rest on the controller board, which will break down when further tightening.
Dismantling the upper deck cover and access to the battery
The first step is always to remove the top platform on which you put your feet, which seems simple, but has its secrets. On the surface of the deck there are four main screw groups hidden under rubber anti-slip linings. Carefully tuck the edges of the rubber, but do not remove them completely so as not to stretch and deform the material.
You'll find screws that need to be unscrewed under the rubber, but that's not all: there may be additional hidden fasteners around the deck, in the junction with the frame. Use a plastic card or a spatula to gently snap the plastic fixtures. Act without fanaticism, the plastic on the Xiaomi M365 is strong enough, but becomes brittle at low temperatures.
☑️ Preparation for deck removal
When you remove the top panel, you'll see the battery pack and the wires that are connected to it, and it's critical that you don't pull the cables abruptly. First, disconnect the main power connector that goes to the controller, and then you can completely remove the deck lid and put it aside.
The nuances of rubber linings
Disassembly of the steering column and removal of the steering wheel
The removal of the steering rack is required to replace the bearings or the brake cable, and the process begins with the removal of the decorative cap at the top of the rod, which hides a control bolt that locks the steering wheel out, and by weakening it, you can separate the upper and lower parts of the steering column.
Then the attention shifts to the bottom, where the rack enters the frame, and there are two powerful screws that often sour due to moisture and dirt, and before twisting, it is recommended to treat them with penetrating lubricant. WD-40 leave 10-15 The threaded joint in this unit experiences maximum vibration loads, so manufacturers use reinforced locks.
When removing the steering wheel, be careful with the light wires and the power button if they are laid inside the rack. In some versions of the Xiaomi M365, the cables go through the entire rod. If the wires are not removed, you may need to remove the lower steering platform, unscrewing the screws around the power button.
- 🛠️ Treat sour screws with penetrating lubricant 15 minutes before work.
- 🔌 Check the integrity of the wire insulation inside the rod before assembly.
- 🧹 Clean the bearing seats of old lubrication and dirt.
After dismantling the rack, it is recommended that the bearings be inspected immediately, if they have a backlash or crunch, they should be replaced. Use bearings with metal anthers for better protection from dust. The lubricant inside should be thick, designed for high speed rotation.
Removal of the motor-wheel and maintenance of the gearbox
The motor wheel is the heart of the scooter, and it takes a lot of care to disassemble it, and to remove the wheel, you have to unscrew the axle that's held on to a few screws on the inside, and often the brake disc is blocking access to it, so you take the brake caliper off first.
Inside the motor is a planetary gearbox. The gears are plastic, and if you run them for long periods without lubrication, they can get worn or cracked. When you disassemble the motor, look carefully at the gear teeth. If you notice metal shavings, it's a sign of wear on bearings or gears.
⚠️ Attention: When assembling a motor wheel, make sure that the phase wires are positioned correctly. Incorrect connection or pinching of the wire with the lid can lead to instantaneous failure of the controller.
The gearbox lubricant should be specialized, load-resistant, and not thickened in the cold. The excess lubricant is as harmful as its lack: excess can be squeezed onto the motor windings, which will worsen the heat sink. It is optimal to lubricate only the gear teeth and bearings.
💡
Use graphite lubricant or specialised power tool gearbox formulations. A regular lithole can thicken at subzero temperatures, increasing the load on the motor.
Dismantling of the controller and electrical circuit
The controller in the Xiaomi M365 is located at the bottom of the frame, under the deck. It often requires a complete dismantling of the bottom or removal of the entire deck, depending on the modification. The control unit is sealed, but its connectors can oxidize.
When you disconnect the wires, remember or photograph the circuitry. The colors of the wires can vary between batches of scooters. Pay special attention to the connector of the Hall sensors and phase wires of the motor. Twisting the phase contacts when the power is turned on is guaranteed to bring the electronics down.
If you change the controller to a more powerful one (for example, from 250W to 350W or 500W), make sure that the wiring will withstand the increased currents.
Table of the main fastening elements
For ease of assembly, we have prepared a summary table of the main screws used in the design, which will help you not to confuse the fasteners when you reverse assemble, which is especially important for elements with different thread lengths.
| Node. | Type of screw | Number of | Note |
|---|---|---|---|
| Fixing the deck | M5 x 25 mm | 4 pcs. | Hidden under rubber |
| Steering column | M6 x 30 mm | 2 pcs. | Lower anchorage |
| Charging cap | M3 x 10 mm | 2 pcs. | Inside the niche |
| Motor wheel. | Special screws. | 6 pcs. | Requires fixation |
💡
Use the table as a checklist for reverse assembly, and losing even one small screw can cause vibrations and the plastic elements of the case to break down.
Assembly and initial launch
The way you assemble it is reversed. The rule is not to tighten the screws to the point at once. First, make all the fasteners, align the elements, and then make the final puff, which is especially important for the deck lid, to avoid skewing and creaking.
Before installing the top deck cover, make sure to check the weight scooter. Connect the battery, turn on the power and check the engine, brakes and lights. Make sure all connectors are snapped to a characteristic click.
- 🔍 Visually check the absence of unnecessary parts after assembly.
- 🔊 Listen to the engine: there should be no grinding.
- 🛑 Check the brakes before the first trip.
⚠️ Warning: After assembly, make the first ride in gentle mode. 10-20 The mile will help new lubricants and seals to stand in their places.
Regular maintenance and proper disassembly will extend the life of your Xiaomi M365 for years. Don't be afraid to disassemble the equipment, if you understand the principle of its operation and take precautions. Clean contacts and the presence of lubrication in the friction nodes is the key to reliable operation of electric vehicles.
