REPLACING TIMING CHAINS
The timing chain is considered one of the main parts of a car engine, and transmits the torque from the crankshaft to the camshaft. The performance of the entire car depends on this mechanism operation.
Nowadays there are two types of timing chains:
- Roller chain
The rollers are interconnected by means of plates and pins. A gear tooth enters after each roller link, due to which the chain sprocket engages with the chain and transmits torque from the crankshaft to the camshaft. This chain category may have single roller and double roller options.
- Silent chain
The silent chain is made of links (plates) connected to the adjacent one with a pin. At the moment when the plates are bent, a recess is formed on the inner radius, where a sprocket tooth enters and engages with the chain.
Compared to roller chains, the silent chain option has a longer operation life and makes less noise, but such chains require better engine oil quality.
Manufacturers recommend changing the chain after about 200,000 km. A more precise replacement time depends on the car model and the quality of the installed chain. Scheduled replacement of the timing chain ensures optimal engine performance. Such replacement also prevents damage to the car engine.
It is recommended to replace the chain together with rollers, tensioner and gears, as it is not recommended to put a new timing chain on worn rollers. Procuring all the parts in a set is the best way to avoid the risk of incompatible parts.
For these reasons, proper and timely maintenance at the AUTOMIX.EE car service is important and prevents engine damage.
