**"A slight squeeze is all it takes to fine-tune the gear position."**

**"Place it above the planetary gear set to check if the position is correct."**

**"If positioned correctly, it should fit in easily."**

**"Depending on your needs, you can install three ratchet devices or just one. Personally, I prefer installing one to avoid the spring tension affecting the rotation efficiency."**
