🧩 Main function:
The balancer belt is responsible for transmitting motion to the balancer shafts , which rotate in the opposite direction to the crankshaft to reduce vibrations caused by engine rotation, especially in four-cylinder engines that naturally suffer from some imbalance.
🔧 Its location in the engine:
- It is usually located on the front of the engine , next to the main timing belt.
- Connects the crankshaft and balance shafts.
⚙️ Its features:
- Similar to a regular timing belt but usually smaller in size.
- It works in precise synchronization with the rest of the engine to reduce vibration and improve smoothness.
🔁 When will it be changed?
- It is often changed along with the main timing belt , i.e. between 80,000 and 100,000 km (according to the manufacturer's recommendations).
- Neglecting to change it may result in belt failure, annoying vibrations, or internal engine damage.
🚗 Cars that contain it:
- Not all cars have this belt.
- It is found in some Mitsubishi, Honda, Hyundai, some Toyota, and Mazda engines , especially engines designed to improve balance without using dual crankshafts.
