Where is the drive pulley on an alternator?
Where is the drive pulley on an alternator?
A drive pulley is attached to the rotor shaft on the front of the alternator. When the engine is running, the crankshaft turns the drive belt, which in turn spins the pulley on the rotor shaft.
How is the alternator connected to the engine?
A drive pulley is attached to the rotor shaft on the front of the alternator. When the engine is running, the crankshaft turns the drive belt, which in turn spins the pulley on the rotor shaft. In essence, the alternator transfers the mechanical energy from the engine into electrical power for the car’s accessories.
How are the finger poles of an alternator arranged?
The triangular finger poles fixed around the circumference of the rotor are staggered, so the north and south poles alternate as they surround the wire rotor field windings. This alternating pattern creates the magnetic field that in turn induces voltage into the stator.
Where are the vents located on an alternator?
If you closely inspect an alternator, you’ll find it has vents on both the front and back side. Again, this aids in heat dissipation. A drive pulley is attached to the rotor shaft on the front of the alternator. When the engine is running, the crankshaft turns the drive belt, which in turn spins the pulley on the rotor shaft.
Where do you put the alternator belt on a four cylinder car?
Many four cylinder vehicles have transverse mounted engines, meaning the engine is mounted at a ninety degree angle from the chassis, placing the belts on the side of the engine bay instead of the front. Look for cracks in the belt. A significant sign that your alternator or serpentine belt needs replacing is visible cracking along the belt.
How to know if your alternator is working properly?
1 Check the drive belt or serpentine belt. Look for signs of wear or damage like cuts, shiny spots or missing chunks under the belt. 2 Also, check the belt tensioner for proper operation and damage. It should rotate freely. 3 Make sure the alternator is properly mounted. 4 Check the alternator for noises.
How big of a drive do you need for an alternator?
It is possible that your vehicle uses a 3/8 inch drive or even a bolt on the tensioner pulley, so refer to your particular vehicle’s service manual to ensure you have the appropriate tools. Rotate the wrench clockwise to relieve the pressure it is placing on the belt.
What causes an alternator to go over base voltage?
If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
