My family just bought a five-sign tricycle, and it doesn't work well after only a few days. At first, the clutch bearing was broken, but later it was not easy to use when it was replaced. I don't know how to adjust. Your tricycle may be equipped with a gear lock. When adjusting, first remove the gear lock lever, adjust the release claw lever to the lowest position of the release claw to lock the lever nut, and then adjust the free clearance between the clutch release lever and the release bearing, so that the release lever and the release bearing are just not in close contact. Try the clutch release effect. If the release is complete, just install the gear lock lever. When adjusting the gear lock lever, pressing the clutch pedal will depress the gear lock rocker arm, and the gear lock rocker arm will automatically return to the gear position. If your tricycle doesn't have a gear lock, just weld the short arm of the clutch pedal to 1.5-2.0 cm to make a hole with a diameter of 8 mm, and adjust the gap between the clutch release claw and the release lever according to the above adjustment method.
