Yes, you can bypass an idler pulley, but it's not generally recommended. Bypassing it may lead to issues with belt tension, belt wear, and overall engine performance. If the idler pulley is malfunctioning, it's usually better to replace it rather than bypass it to ensure proper function of the serpentine belt system. Always consult your vehicle's service manual for guidance.

A moveable pulley can be identified by its ability to move with the load it is lifting. Unlike a fixed pulley, which remains stationary, a moveable pulley is attached to the load itself, allowing it to change the direction of the force applied while also reducing the amount of force needed to lift the load. Additionally, a moveable pulley typically has a wheel that is mounted on a frame, and it often features a rope that runs through it, allowing for easier lifting and maneuvering.

Combining a fixed pulley and a movable pulley creates a block and tackle system, which increases mechanical advantage and allows for easier lifting of heavy loads. The fixed pulley changes the direction of the force applied, while the movable pulley reduces the amount of force needed to lift an object by distributing the weight across multiple segments of rope. This setup is widely used in various applications, such as construction and sailing, to enhance efficiency and reduce the effort required to lift heavy items.

An axle pulley is typically constructed from durable materials such as steel or high-strength plastic to withstand mechanical stress. It features a central hub that fits onto an axle, allowing it to rotate freely. The pulley has a grooved rim to accommodate a belt or rope, facilitating the movement of loads.
