The Crankshaft Pulley transmits the engine's torque to the serpentine belt system. Furthermore, it dampens crankshaft vibrations. Fitted to the crankshaft and sometimes called a harmonic balancer, the Crankshaft Pulley has grooves that direct the belt that powers the alternator, power steering pump, and air conditioning compressor. An elastic rubber layer that joins the hub and inertia ring absorbs twisting pulses, allowing the Crankshaft Pulley to mitigate noise while also safeguarding component bearings and belt surfaces against overheating or slipping. If the rubber ring wears out, then belt slipping, squeal, and reduced charging output can occur. Therefore, the Nissan Xterra drive assembly should be paid timely attention for steady operation of the vehicle. The belt path of the Nissan Xterra is also dependent on a healthy tensioner/idler system and the Crankshaft Pulley to keep the single serpentine belt on track. The Nissan Xterra component Crankshaft Pulley is not a specific part for a specific task because the same pulley sends rotational energy outward while cushioning vibration inward.
