TOYOTA 13568-19176 Timing Belt

The genuine TOYOTA 13568-19176 timing belt (BELT, TIMING) is an essential component of the engine internal valve train, ensuring synchronized drive between the crankshaft and the camshaft. The timing belt's function is to maintain strictly timed valve opening and closing relative to piston movement, ensuring optimal combustion and efficient engine operation.

Technical Characteristics and Role

The timing belt is manufactured from high-tensile, wear- and heat-resistant synthetic elastomer, reinforced with high-strength internal tensile cords and a durable fabric facing. The drive is delivered directly and slip-free through a precision toothed profile.

Wear, Failure, and Maintenance

In interference diesel engines, timing belt failure (tooth shear, fraying, snapping) results in mechanical collision between valves and pistons, causing catastrophic engine damage. Common signs of wear include rubber cracking, softening due to oil contamination, tooth profile wear, and abnormal noise caused by loss of tension. Replacement must be carried out in accordance with manufacturer-specified service intervals and mileage.
