It probably depends on the pully in question. A Power Steering pump pully for example would probably not be considered part of the powertrain. A water pump pully on the other hand may be. Really there is no true definition of what is "powertrain". If you are referring to a warranty issue though that is different. Someplace somewhere a team of lawyers for warranty companies decide what is and isn't included under different warranty packages. Each warranty company has a list of every repair you could think of, and has predetermined weather or not they cover that item. Any time you buy an extended warranty for any vehicle it is a good idea to find out what they really cover. Unless you buy the better warranty packages they usually won't cover a whole lot.
The alternator belt is an important part inside a car. It is used for providing power to the alternator via the crankshaft pulley's force.
The middle part of a pulley is called the wheel or sheave. It is the round component that rotates on an axle and around which the belt or rope travels. The wheel is typically grooved to keep the belt or rope in place and provide a better grip for transmitting force.
Pulley.
The idler pulley or tensioner pulley?
No, an alternator is not part of the power train. It is an auxiliary to provide electricity.
Tensioner assy: 38158 Just the pulley: 38009
is camshaft part of power train component or engine
Yes, it's part of the drivetrain, also known as a power train.
A fan belt is a type of simple machine that uses the pulley system. That is how the belt gets turned by the wheels.
Idler pulley takes up the extra slack from the serpentine belt.Serpentine belt, drives accesories from the crankshaft ie., usually,. water pump, power steering pump, altenator,air conditioner compressor. Older vehicles had separate belts for driving these componants and each had it's own adjustment location which was done manually,[which is why belts would schreech when loose] most of the newer stuff has idler pulleys which are self adjusting [spring loaded]the bad part is serpentine belts can be pricey and the bearing in the idler pulley can tend to wear out and the whole unit has to be replaced. L. Keedy It controls the routing of the belt. The amount of contact betwen a pulley and the belt determines how much power will be available for the alternator, power steering pump or water pump. One of the idler pulleys is mounted on an arm that is spring loaded to keep force on the pulley. It's called a tensioner pulley or belt tensioner. That makes sure the belt is tight and able to transfer power properly.

To tighten the tensioner pulley on a 2001 Suzuki Grand Vitara 4WD, first, locate the tensioner pulley, which is typically part of the serpentine belt system. Use a ratchet and socket to rotate the tensioner pulley counterclockwise, relieving tension on the belt. Once the belt is properly positioned, slowly release the tensioner to apply tension to the belt. Ensure that the belt is aligned correctly on all pulleys before starting the engine.
