These failures may occur before working out the nominal belt life and lead to an intensive engine injury, thereby resulting pricey repairs. Timing belt failures are generally resulted from three causes, that is, lack of a tooth, fiber separation on belt sides, and teeth splitting. Three optical sensors with laser beam whose diameter is 0.6 mm was located on appropriate positions and it's used to provide error signal resulted from disturbance of laser beam flows as a consequence of failure. The error signal is processed by the processor, which is independent from the digital control unit (ECU) to alert the driver or ECU, instantly. Experimental apparatus which consists of two camshaft pulleys and an idler pulley with belt tensioner has been set up to simulate actual engine situations.

Note: Gates recommends that Poly Chain GT ® CarbonTM Belts run only in Poly Chain® GT ® 2 sprockets when used for brand spanking new functions. Note: PowerGrip® GT ®2 Belts have to be used with PowerGrip® GT®2 sprockets for brand spanking new designs. Note: 8mm and 14mm pitch PowerGrip® GT ®2 Belts can be utilized to change not-Gates curvilinear belts in most instances. Note: 5mm pitch also available in Poly chain® development. Warning: Don't use Gates belts, pulleys, or sprockets on any aircraft propeller or motor drive programs or in-flight accessory drives. Gates products are usually not designed or intended for aircraft use.

3. Remove different elements as essential to entry the water pump. This could embrace any brackets or mounts that may be in the best way. Take off what is necessary and try to avoid taking off greater than what is necessary. As the bolts and brackets are removed, they should be placed onto a service cart so as and a fast note written to make re-set up simpler. I used to put white paper floor mats on top of my service cart and write with a black marker, to jog my reminiscence. It isn't that I couldn't work out where the bolts go, but this way I did not have to waste time unnecessarily. 6. If removing a timing belt, make sure of the timing marks before disassembly.
