5. Assembly Instructions
This kit requires careful assembly. Follow the general steps below. Refer to the included visual instructions (if provided with your specific kit) for detailed part placement. The images below illustrate key assembly stages and the final product.
5.1 Unpacking and Preparation
- Carefully open the package and lay out all components on a clean, flat surface.
- Sort the building blocks by type and color to facilitate easier assembly.
- Familiarize yourself with the different types of beams, pins, gears, and suspension elements.

5.3 Independent Suspension and Differential Integration
- Assemble the independent suspension units for each wheel, including springs and shock absorbers.
- Integrate the differential gear mechanism into the central part of the chassis. Pay close attention to gear alignment for smooth operation.
- Attach the steering axle components to the front suspension units, ensuring free movement.

6. Operating Instructions
The MOC 4WD Building Block Chassis is designed for demonstration and integration into larger building block models. It is not a remote-controlled vehicle unless further modifications are made.
- Suspension Test: Gently press down on different parts of the chassis to observe the independent suspension in action. Each wheel should move up and down independently, absorbing pressure.
- Steering Test: Manually turn the front wheels to check the steering mechanism. The wheels should turn smoothly left and right.
- Differential Function: Observe the differential gears when rotating the wheels. The differential allows wheels on the same axle to rotate at different speeds, which is crucial for smooth turning.

7. Maintenance
Proper care will ensure the longevity and functionality of your building block chassis.
- Cleaning: Use a soft, dry cloth to wipe away dust. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the assembled chassis or loose parts in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
- Inspection: Periodically check for any loose connections or worn parts. Re-secure any loose pins or beams to maintain structural integrity.
- Lubrication (Optional): For smoother gear operation, a small amount of dry lubricant (e.g., silicone-based spray) can be applied to the differential gears, ensuring it is safe for plastic.
8. Troubleshooting
- Parts not fitting: Ensure you are using the correct parts as per the instructions. Apply gentle, even pressure. Do not force parts together, as this may cause damage.
- Loose connections: If parts feel loose, double-check that pins are fully inserted and beams are securely connected. Disassemble and reassemble the section if necessary.
- Wheels not turning smoothly: Check for any obstructions around the axles or in the differential. Ensure all gears are correctly aligned and meshing properly.
- Suspension not working: Verify that the springs and shock absorber components are correctly installed and not jammed.
- Missing parts: In the rare event of missing parts, please contact the seller, Inspire Minds Store, with your order details and a description of the missing components.
9. User Tips
- Organize Your Build: Before starting, sort all pieces into categories (e.g., by type, length, or color). This will significantly speed up the assembly process.
- Patience is Key: Building block kits, especially those with complex mechanisms like differentials and suspensions, require patience. Take your time and enjoy the process.
- Creative Expansion: This chassis provides a robust foundation. Feel free to use additional compatible building blocks to design and construct your own custom vehicle body or other enhancements.
