Which is the correct way to tension a V-belt?
The meter will report the belt tension in units of force. On new installations, hand rotate the system at least one full revolution of the belt in order to seat and normalize the components. When tensioning an array of V-belts, use a single belt toward the center.
What happens if there is too much tension in a belt?
If they are too loose, there is slippage, rapid belt or sheave wear and, ultimately, loss of both energy and productivity. Conversely, if there is too much tension, the excess strain on the belts, bearings and shafts causes premature wear of these components.
How do you tension a power transmission belt?
First determine the proper deflection force required to tension the timing belt. Deflection forces are given in the timing belt manufacturer’s tables and/or power transmission drive design online calculators. Then place a straightedge across the top of the timing belt.
Which is the best tension meter for belts?
The sonic tension meter provides the most accurate tension measuring available. Timing belts, like string, vibrate at a particular natural frequency based on mass and span length.
Where is the tensioner located on a belt?
The tensioner arm is found on the bottom of the tensioner, and if you press on it, it will work against the spring, delivering enough slack so that you can adjust or remove the belt. Adjusting the drive belt tensioner is not something you should attempt to do yourself – leave this job up to a pro.

What should I do if my serpentine belt tensioner is wrong?
The serpentine belt is absolutely vital to the function of your vehicle, and if you end up with a belt problem due to an improperly adjusted tensioner, the damage can be catastrophic. The most popular service booked by readers of this article is Drive Belt Tensioner Replacement.

How does a drive belt tensioner work on a car?
In order to keep the proper tension on your vehicle’s serpentine belt, a drive belt tensioner is used. This is a pulley that is either mounted to an adjustable pivot point or a spring mechanism. If you open up the hood of your car, you’ll see that the serpentine belt is on the front of your engine. It is the long one.
What to do if your belt tensioner is not working?
Use a wrench to move the belt tensioner arm through its range of motion. What you want to see is that there is resistance to the movement that you apply. If you notice that there is no resistance at all, then the problem is in the tensioner spring.
What does a loose belt tensioner sound like?
If the drive belt noise resembles a squeal or a squeak, it is possible that the belt tensioner is loose. This is especially the case when starting the engine first thing in the morning. Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound.
How do I change the a / C belt without a tensioner?
How in the heck do I change out the A/C Belt without having a tensioner?! I was reading through my Haynes manual and they stated I have a belt tensioner located on the bottom of the A/C unit and I do not have such thing. Beyond annoyed and confused. Any help would be appreciated! Maybe this will help.
What’s the best way to change a timing belt?
Loosen the mounting bolt (s) holding the belt tensioner using any special cam holding tools, while following the service manual. Do not remove the tensioner completely unless replacing it. Instead, pivot the spring-loaded tensioner away from the belt and then retighten the mounting bolt (s) to hold the tensioner in the loose position.
What’s the best way to replace a serpentine belt?
Install the new belt Replacing the serpentine belt is as simple as threading it into position, cranking the tensioner and slipping the belt over the tensioner pulley, or nearest pulley up top. Belt tensioners are mostly spring tension. Once installed, the spring retains pressure to the belt.
What’s the best way to remove a pulley belt?
Use a ratchet or breaker bar that fits into the bolt and release the tensioner. Then unroute the belt carefully, taking care not to disturb or damage the network of pulleys and peripherals. After removing the belt, inspect it for signs of damage. Many belts wear out over time, but some wear down due to misalignment or other issues.
