When checking the accessory drive bells, there are usually three types that are observed on the cars today with a healthy drive bell exhibiting no deep cracks since it may result in flex and accumulation of heat which may cause the belt to break. Critical reinforcing cords are exposed to excessive wear through worn covers, and it is possible to wear or break serious cords through the use of a bell that is too wide. Belts are to be examined as to glazing or cracking, glazed belt feeling smooth due to the slippery nature whereas a good belt has a slight texture of the fabric or fabric. The cracks normally begin at the inner edge and run out and this makes replacement of any worn or damaged drive belts at once or rather all at once a precautionary measure. The alternator belt ought to be tested to confirm that it has the right tension by pressing on the belt, and when purchasing a new or used belt, there are particular tolerances of deflection of the assembly. In case of any adjustments, loosen the adjustment bolt and through bolt of the alternator then the adjustment screw is to be turned to a desired tension which should be clamped using given torque values. The same method is used to the power steering and air conditioning belts and bolts are loosened and a porybar is used to attain the right amount of tension. The process of installing or removing of belts is described in specific steps depending on the type of engine with detailed torque requirements given to connect bolts once they have been adjusted. Removal of belts involves it being important to remember the direction of belts and obey the instructions of installation to be able to install new or recycled belts correctly.
