The Xiaomi Mijia M365 has proven itself to be a reliable vehicle, but even time-tested models have punctures or wear of rubber. Replacing the camera or tire requires dismantling the front wheel, which at first glance seems to be a difficult procedure for a beginner. However, with the right set of tools and understanding the design of the unit, you can perform the repair yourself, saving time and money on the services of the service center.
The main difficulty is the tight fit of the tire and the specific design of the sleeve of the motor-wheel. Regular maintenance of the chassis extends the life of the device, so it is important to know how to properly dismantle the unit without damaging the electrical contacts. In this article, we will discuss in detail the process of removing the wheel, paying attention to the nuances of working with the brake disc and wiring.
Before any work begins, you need to have a clean surface, good lighting and access to electricity to charge the device after assembly. Don't ignore safety, as working with sharp tools and electrical components requires concentration. Below we will look at all the stages of preparation and the dismantling process.
Tools and workplace preparation required
To successfully complete the task, you will need a specific set of tools that are not always in a standard home medicine cabinet. Particular attention should be paid to the quality of hexagonal keys, since cheap metal can lick the edges of the bolts on the frame of the scooter.
You'll also need items to protect your hands and surfaces, rubber can be stained with lubricant or dirt, and sharp edges of the tire can injure your skin, prepare rags or paper towels to wipe the parts while you're working, and this will help you avoid getting dirt inside bearings or electrical connectors.
- 🛠️ Set of hexagonal keys (mandatory presence of 8 mm and 3 mm)
- 🔧 Split key for spokes or pliers (for adjustment, if required)
- 🧤 Protective gloves and mounting blade for tires
- 🧼 Soap solution or talc to facilitate the installation of the tire
It's important to make sure that the scooter is off. Press the power button several times or hold it down to make sure that the device is not in active mode. Although we're working with the mechanical part, accidentally pressing the gas trigger when the wheel is removed can cause damage to the controller or injury.
⚠️ Warning: Never start disassembling if the battery is fully charged before 100% It's very high voltage, ideally if the charge is high. 40-60%.
☑️ Preparation for repairs
Dismantling plastic covers and access to fasteners
The first step to freeing the wheel is to remove the decorative elements: Plastic motor-wheel covers are attached to the screws, which are often hidden under stickers or simply tightly pressed. Carefully inspect the perimeter of the wheel to locate all mounting points.
Use a 3mm hexagon to twist the screws on the side covers. Be careful not to damage the plastic, which can become brittle over time. If the screws don't twist, don't use excessive force - it's better to drop a little penetrating lubricant and wait a few minutes.
Once the lids are removed, you will have access to the inner structure of the wheel and the brake disc, and at this point it is important not to lose small screws, as they tend to roll in the most inappropriate places, and it is recommended to immediately fold them in a magnetic tray or a separate jar.
Look at the wiring condition that fits the wheel axis. The engine cable should be intact, free of clamps and insulation damage. If you notice any scuffs, it's a signal that you'll need to pack the wiring more carefully when you're assembled, perhaps using an extra insulation tape.
Disconnection of brake disc and electrical contacts
The brake disc on the Xiaomi Mijia M365 is attached to the hub with several bolts. To remove them, you will need an 8 mm key. Unscrew the bolts cross-cross to avoid distortion of the disc. After removing the bolts, carefully remove the disk itself, trying not to touch the working surface with your fingers, as the fat from the skin can worsen braking.
The next critical step is to turn off the electrical connector. The wires exit the wheel axis and connect to the main harness inside the fork. The connector is usually protected by a plastic casing. Carefully bend the lock and open the contacts. Don't pull the wires themselves, hold on to the plastic part of the connector.
What to do if the connector does not turn off?
Make sure that the connector is free of moisture or dirt. If the scooter was in the rain, there may be condensation inside the connector. Wipe the contacts with a dry wipe or blow them with compressed air. Contact oxidation is a common cause of engine errors and power loss.
| Component | Type of attachment | Tool. | Moment of puffing (example) |
|---|---|---|---|
| Engine cover | M3 screws | Hexagon 3 mm | Medium. |
| Brake disc | M5 bolts | Hexagon 8 mm | High-pitched |
| Axis of wheels | M10 nuts | Key 10 mm/12 mm | Very tall. |
| Electrician. | Jack | Manually. | - |
⚠️ Warning: When you disconnect the connector, remember or photograph the position of the wires.
Removal of the wheel from the scooter fork
Now that the disc and the wires are disconnected, you can start to dismantle the axis itself. The wheel is held by two nuts on either side of the fork. Usually you use a 10 mm or 12 mm key, depending on the modification and the year of release of the scooter. The nuts can be tightened very tightly, so you may need a collar or a key extension.
Unscrew the nuts gradually, first one, then the other until they come off the thread. Hold the wheel with your hand so that it does not fall to the floor when you completely remove the nuts and washers. The weight of the motor wheel is significant, and the fall can damage the magnets or winding.
Carefully pull the axle out of the fork. If it doesn't come out, sway the wheel up and down a little. Don't knock the axle out with a hammer, because you can damage the thread or the bearings. Once you remove the axle, the wheel will be free from the fork. Put it on the prepared surface.
At this point, look at the seats in the fork, there should be no cracks or heavy metal production, the integrity of the fork is critical to driver safety, and if you find deformities, you can't continue to operate the scooter.
Replacement of camera and tires: technical nuances
Once the wheel is removed, you have to replace the camera or the tire, and you have to completely deflate the air if you have any left, use a spool cap or a thin object to press the nipple, and make sure that the camera is completely deflated before you start disassembling.
With the mounting blades, gently tuck the tyre side and remove the camera. Carefully avoid pinching the camera between the tyre and the rim, as this will cause a new puncture immediately after pumping. When you install a new camera, slightly pump it up so that it takes shape, but does not swell completely.
It's important to place the camera nipple correctly, and it should come out strictly perpendicular to the rim, and before you put the tire in place, sprinkle the camera with talc or soap solution, which will reduce friction and allow the camera to spread out evenly inside, without creases.
💡
Use baby powder (talc) inside the tire before installing the camera, which will prevent rubber from sticking together and reduce friction, prolonging the life of the camera.
When you board the tire, make sure that the tool does not damage the camera. After assembly, pump the wheel to the recommended pressure (usually indicated on the sidewall of the tire, about 45-50 PSI). Check whether the tire is evenly settled along the entire perimeter of the rim.
Assembly of the node and final inspection
The assembly is done in reverse disassembly. Insert the wheel axis into the fork, making sure that the brake disc (if it is already on the hub) falls into the brake caliper. If the disc has been removed, set it in place and tighten the bolts cross-cross with force.
Put the washers on and tighten the axis nuts. The puff should be very reliable, because this knot has a high vibration load. After the nuts are tightened, plug in the electric connector. The characteristic click of the locker will confirm the correct connection.
Put the plastic motor-wheel covers in place. Make sure the wiring is not clamped by the edges of the plastic. Turn on the scooter and check the engine's performance on weight. The wheel should rotate smoothly, without any extraneous sounds or beats.
Be sure to check the brakes before your first trip. Pull the trigger and make sure the disc locks effectively. If the brakes are not working properly, you may need to adjust the caliper or replace the brake pads.
⚠️ Attention: After the first trip (5-10 Be sure to check the tightening of the axle nuts and brake disc bolts. They can weaken under the influence of vibration.
