Synchronous Belt Drive System (SBDS):
On some models, (including 1.6 HDI, DV6TED4), problems with rust inside the SBDS have been reported. In certain cases, this has been found to cause excessive noise inside the drive system. Gates, one of the world’s largest manufacturers of belts and tensioners, points out that this requires extra vigilance on the part of the mechanic when making the diagnosis. Increased noise is often a symptom of an operational issue within the SBDS . For example, component wear, misalignment or incorrect tension of the belt are all likely sources of excessive SBDS noise. Careful inspection is required to rule out all alternative causes.
Auxiliary Belt Drive Systems (ABDS):
As the OE manufacturer of the ABDS belt on the 1.6 e-HDI, DV6TED, Gates points out that this engine is equipped with a belt-driven stop-start system. This requires a specific type of ABDS belt, one that has been specially designed for use with a stop-start system. This is because stop-start belts are designed to cope with the greater stresses and strains that are particular to these applications. An example is the (6PK1020EMD), the only suitable belt for this specific drive is the Gates aftermarket replacement. EMD stands for Electro-Mechanical-Drive.
