Dayco RB25 Timing Belt Kit

The basic function of a timing belt is to transmit synchronous movement from one driven shaft to another. This is achieved by “meshing” between the tooth of the belt and the tooth of the pulley. A timing belt has a complex structure and is made up of three elements. A rubber compound (usually highly saturated nitrile) that makes up the toothed part and the back of the belt. Nylon (sometimes a double layer) is extremely flexible and used to cover the teeth. High modular fibre glass cords, which are resistant to tensile stress and will not deform give the belt its outstanding stability.

Why replace the timing belt alone? Worn or wearing tensioners, pulleys and idlers can cause a new timing belt to fail in a very short time. A timing belt failure can result in costly engine damage. Dayco® Timing Belts, when replaced in conjunction with the tensioner, idler Pulley and oil seals, restore the optimum operating conditions for the timing drive system.


All Dayco timing kit components meet or exceed OEM specifications.
