1. Introduction
This manual provides instructions for assembling and operating the wishiot T1324 MOC 4-Speed Gearbox Manual Transmission Kit. This DIY technical model is designed for enthusiasts aged 14 and above, allowing for the construction of a functional 4-speed gearbox using building blocks. Depending on the bundle purchased, it may include an M motor and battery box to enable motorized functions.
2. Safety Information
- Age Recommendation: This product is recommended for individuals 14 years and older.
- Small Parts Warning: The kit contains small parts which may pose a choking hazard. Keep out of reach of young children.
- Battery Safety: If your kit includes a battery box, ensure to use the correct type and size of batteries (AA or AAA, not included). Do not mix old and new batteries, or different types of batteries. Insert batteries with correct polarity. Remove batteries if the product is not used for an extended period.
- Electrical Components: The M Motor and battery box are electrical components. Avoid exposing them to water or extreme temperatures.
3. Package Contents
The kit consists of loose building block parts that require self-assembly. Please verify your package against the bundle purchased:
- Bundle 1: 1PC Gearbox (loose parts for assembly)
- Bundle 2: 1PC Gearbox (loose parts for assembly) + 1PC M Motor
- Bundle 3: 1PC Gearbox (loose parts for assembly) + 1PC M Motor + 1PC AAA Battery Box (batteries not included)
- Bundle 4: 1PC Gearbox (loose parts for assembly) + 1PC M Motor + 1PC AA Battery Box (batteries not included)
Note: Remote control functionality, if desired, typically requires additional components (e.g., a remote control unit and receiver) which are not explicitly listed in these bundles and may need to be purchased separately.
4. Assembly Instructions
The wishiot T1324 is a DIY kit, meaning all parts are loose and require assembly. While detailed step-by-step instructions are not provided in this manual, the following diagrams illustrate the assembled product and its components to guide your construction. Refer to the product packaging or manufacturer's website for comprehensive building guides if available.

To shift gears, manually move the gear lever to the desired position as indicated in Figure 5.1. The gearbox provides four distinct speeds (gear ratios) for various applications in your MOC creations.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the building blocks. Avoid harsh chemicals or abrasive materials.
- Storage: Store the kit in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
- Inspection: Periodically check for any loose or damaged parts. Replace any broken components to ensure proper functionality and safety.
7. Troubleshooting
- Gears not engaging: Ensure all gears are correctly aligned and fully seated on their axles. Check for any obstructions between the gears.
- Motor not running (if applicable): Verify that batteries are correctly inserted with the proper polarity and are not depleted. Ensure the motor is securely connected to the battery box.
- Loose connections: If parts feel wobbly, disassemble and reassemble the affected sections, ensuring all pins and axles are fully inserted.
