Schaeffler Timing Belt Set - 530 0945 10

Timing belts in modern internal combustion engines are subject to constantly increasing demands. To make the belts more durable, more resistant and quieter to operate, their materials and manufacturing techniques require constant development. These developments not only give rise to new generations of improved timing belts, but also ensure that existing versions can run smoothly and more efficiently. Due to the changes made for the current series, recently produced timing belts may differ from older versions in the following ways: • The back fabric may have a rough surface (figure 1) rather than a smooth one. This type of surface produces less noise when the belt is in operation. • The tooth profile may have a white or black coating made from polytetrafluor ethylene (Teflon®) (figure 2). This reduces friction and wear on the timing belt. • The back fabric may have one or more seams (figure 3). These joins are created before the belt is vulcanized to aid the manufacturing process. • The shape and/or structure of the tooth profile (page 2) may differ from previous versions if more suitable tooth shapes have since proven to be effective and have been adopted.
