Why is it necessary to regularly inspect or replace the engine drive belt?
1 Answers
Regular inspection or replacement of the engine drive belt is necessary because the belt is a rubber product prone to aging, which can lead to serious mechanical failures. Here are details about the belt: 1. Determine replacement intervals based on mileage: The belt is a consumable part. Once it breaks, the camshaft will not operate in sync with the timing, which can cause severe damage due to valve and piston collision. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer. 2. Shorter lifespan than metal gears: The drive belt is a critical component of the engine's valve timing system. It connects to the crankshaft and ensures accurate intake and exhaust timing through a specific gear ratio. Belts are used instead of gears for transmission because they produce less noise, have minimal variation, and are easier to compensate. However, it's evident that the lifespan of the drive belt is shorter than that of metal gears, so regular belt replacement is essential.
