MS Timing Belt Pulley is part of the timing belt system for an automobile. A timing belt is one way to control the opening and closing of engine valves by connecting the crankshaft to the camshaft of the vehicle. Generally, the timing belt does this by having teeth that lock into the teeth of the two gears for the crankshaft and camshaft.
A timing belt is one of the several belts used in conventional cars and other vehicles. A serpentine belt is a belt that drives various other engine accessories off of the crankshaft. The serpentine belt can run an alternator, power steering pump, and air conditioning compressor. In some vehicles, these jobs are split between multiple belts, where a vehicle usually has only one timing belt pulley.
