Can the belt of the Dolphin be replaced with a chain?
2 Answers
The belt of the Dolphin cannot be replaced with a chain. Reasons: Chains are mainly divided into two types: sleeve roller chains and toothed chains. Among them, roller chains are affected by their inherent structure, resulting in relatively more noticeable rotation noise compared to timing belts. The transmission resistance and inertia are also correspondingly greater. The tension of the belt is achieved through an automatic tensioner wheel, while the chain relies on a special, wear-resistant tensioning mechanism for automatic tensioning. If you want to replace the timing belt with a timing chain, the automatic tensioning mechanism must also be replaced, which incurs higher costs. Function: Both timing belts and timing chains are power transmission devices in cars. The power generated by the engine needs to be transmitted through them to drive the car forward. Replacement Notes: Over time, belts may age or break. Generally, belts should be replaced every three years or 50,000 kilometers to ensure driving safety.
I've modified motorcycles before, and this issue is really particular! If the Xiaohaitun is a scooter, changing to a chain drive would be a major project. Chain drive and belt drive are completely different—first, check if there's enough space in the engine compartment to fit the chain sprockets. Chains rattle and require regular oiling and maintenance, unlike belts that run quietly for tens of thousands of kilometers. The modification cost is at least several hundred yuan, and if the chain quality is poor, it could snap mid-ride, which is dangerous. Actually, the factory installs belts for comfort and quietness; if you really want sporty performance, it's better to buy a chain-driven model outright. The motorcycle's drivetrain affects the whole system—for regular commuting, it's really not worth the hassle.
