What is a tensioner spring?
A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring-loaded bicycle chain tensioner, the tension it creates.
Where is the belt tensioner on a car?
Obtain the belt routing diagram from the repair manual if you’re replacing the belt as well. Locate the automatic belt tensioner on the side or front of the engine. Inspect the tensioner to use the right tool to release the tension on the belt so you can remove it from the pulley.
What was the timing belt tensioner for the Toyota 3VZ?
Also the timing belt tensioner Toyota used for the 3VZ from 1988 1992 is a spring loaded tensioner, while the belt tensioner for the 1993 – 1995 3VZ utilizes a hydraulic design. To facilitate the new hydraulic tensioner, a machined recess and a drilled and tapped hole were added to the front of the right hand side cylinder head.
Can a pulley be replaced on a tensioner?
The tensioner’s job is to apply the correct amount of tension to the serpentine belt by employing an internal coil spring. The pulley is then attached to the tensioner and acts as a guide for the tensioner to function. In most vehicle applications, the pulley can be disconnected from the tensioner and then replaced.
Why is my serpentine belt not going back on?
Serpentine belts will fit snugly and allow little to no margin for error. If the belt is not going back on, it’s because it’s not aligned properly, the ribs of the belt are not properly sitting in the grooves on one or more pulleys, or the wrong-sized belt was purchased for replacement.
Why do you need a spring tensioner on a belt drive?
Maintain correct drive tension to ensure smooth operation for maximum power and a long service life. Designed for use on large belt and chain drives, tensioners are spring loaded to provide constant tension and automatic adjustments for pulsating loads. Idler shaft (sold separately) is required.
What does a LG spring tensioner do for your car?
Lg. Built-in springs put constant tension on roller chain to absorb and buffer shock, reduce vibration, and improve drive performance. For technical drawings and 3-D models, click on a part number.
How big is a McMaster spring tensioner chain?

What do tensioners do on a roller chain?
Tensioners take up slack and allow you to adjust tension on your roller chain or belt. A built-in spring allows the adjustment arm to apply continuous tension. They are for use with idler sprockets or pulleys. For technical drawings and 3-D models, click on a part number.
