How do you replace a pulley in an engine?
Turn the pulley bolt counterclockwise with a ratchet and a socket. Remove the bolt, the retaining washer and the pulley. Replace the pulley, washer and bolt and tighten to specified torque illustrated in the repair manual. Replace the tensioner in the engine and replace the bolt. Tighten to specified torque.
How do you replace a pulley on a retaining washer?
Position the tensioner in the vise so you can access the pulley bolt. Turn the pulley bolt counterclockwise with a ratchet and a socket. Remove the bolt, the retaining washer and the pulley. Replace the pulley, washer and bolt and tighten to specified torque illustrated in the repair manual.
How do you change a pulley on a belt tensioner?
Place the automatic belt tensioner into a bench vise, being careful not to overtighten the clamps. Many tensioners are made of lightweight aluminum and can easily crack. Position the tensioner in the vise so you can access the pulley bolt. Turn the pulley bolt counterclockwise with a ratchet and a socket.
How to change fan speed with adjustable pulley?
Divide the 6000 CFM by 5100 CFM to find the ratio of airflow increase. Notice the airflow should increase 17% for the fan to deliver the required airflow. Then multiply the pulley belt diameter of 5.5-in. times 1.17 to find the new belt diameter of 6.44-in.
What is the equation for pulley?
Calculate the work input in a pulley by using the previous readings in the correct mathematical equation: Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height travelled (h).
How does the pulley work?
Artwork: How pulleys work#1: With one wheel, a pulley simply reverses the direction of the force you apply. It doesn’t alter the force in any other way. Now if you add more wheels, and loop the rope around them, you can reduce the effort you need to lift the weight.
How does a pulley help?
The function of a pulley is to lift heavy objects by changing the direction of the force on a flexible cable. It also consists a wheel with a groove in its outer edge and an axle. With the help of ropes, chains or cords, a pulley makes moving objects upward easier. Pulley reduces the force given to get the work done.
What is a simple pulley system?
Pulley systems are simple mechanical devices that are used in a variety of settings to save space and mechanical energy. In their simplest form, they consist of a rope that runs through a grooved wheel. The rope is passed through the wheel and attached to an object that needs to be moved;
