DZ097 Applicable Model: New Jetta New Santana 1.6L Diesel Model year:2014 to present 04C109479H/04E109244A/04E109119H

Individual item details

Timing and tightening wheel: A28139 OE: 04C109479H scroll spring automatic timing and tightening wheel, working principle: optimize the structure on the basis of mechanical tightening wheel. Using a scroll spring combined with a side plate to generate a constant torque, it automatically supplements the tension while absorbing the amplitude of the belt span.

Timing Idler: A68140 OE: 04E109244A Center Hole Fixed Timing Idler: Its main function is to assist in tensioning the pulley and belt, changing the direction of the belt, and increasing the inclusion angle of the belt and pulley. The idler wheel in the engine timing transmission system can also be called a guide wheel.

Timing belt: 163S7M200 OE: 04E109119H Tooth shape: S7M Width: 200mm Number of teeth: 163 Made of high molecular rubber material (HNBR), its function is to maintain synchronous operation of the piston stroke, valve opening and closing, and ignition sequence when the engine is running, under the connection of timing. The timing belt is an important component of the engine’s valve distribution system, which is connected to the crankshaft and matched with a certain transmission ratio to ensure accurate intake and exhaust times. The timing belt is a rubber component. As the engine working time increases, the timing belt and its accessories, such as the timing belt tensioner, timing belt tensioner, and water pump, will wear or age. Therefore, for engines equipped with timing belts, the manufacturer will have strict requirements to regularly replace the timing belt and accessories within the specified cycle.

Reminder:

The timing system accurately opens and closes the corresponding intake and exhaust valves by controlling the opening and closing time of the valves, allowing sufficient fresh air to enter. The main function of the timing belt is to drive the valve distribution mechanism of the engine. The upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel, so that the engine intake and exhaust valves can be opened or closed at appropriate times to ensure that the engine cylinders can suction and exhaust normally. The timing belt is a consumable item, and once the timing belt breaks, the camshaft will not operate according to the timing, which is highly likely to cause serious damage due to the impact of the valve and piston. Therefore, the timing belt must be replaced according to the mileage or time specified by the original factory.
