Mini 4WD Tire Wheel Balancer - Magnetic Type - Correction Jig Tool - Eliminating wobble and achieving balanced, even rotation is crucial! That's where this jig tool comes in! Mini 4WD Tire Wheel Balancer Jig Tool (Wheel Balancing Jig) - Magnetic Type - Includes Mini 4WD Shaft and Magnet Compatible Tire Diameter: 22-38mm We recommend this magnetic type, which has less rotational resistance than bearing types. This is a balancer jig tool that improves stability during running by adjusting the Mini 4WD tire wheel balance. Balanced tire wheels significantly improve straight-line performance and stability, such as during jumps. Set Contents: - Jig Tool Body - Magnet - Shaft * The shaft is cut to fit this jig and can be used immediately. (Please prepare your own wheels and tires) Balance is achieved by floating one side of the shaft axis in the air, with minimal rotational resistance. [How to Use] 1. Set the shaft on the tire wheel to be balanced. (The tire wheel to be balanced should be used by passing the shaft through it.) 2. Confirm that the shaft rotates lightly with only one side floating. 3. Wait until the wheel stops rotating; the heavier side will concentrate at the bottom and come to rest. 4. Mark (indicate) the upper part. 5. Attach a weight (masking tape, etc.) to the wheel rim (inside) where you made the mark. (You can also shave the wheel, but it requires very precise work, so we recommend masking tape.) 6. Rotate again and repeat steps ③ to ⑤ to adjust. 7. As the balance improves, the stopping point becomes ambiguous, and the rotation becomes harder to stop. This is the completed state. After processing, you can feel a significant reduction in vibration when you set it up. This product is manufactured using a 3D printer.
