How Do You Measure V belt tension?
Drive simply deflect until the bottom o-ring is in line with the top of one of the other belts.
What tool do you use to check belt tension?
Belt tension gauges are used to properly check drive belt tension on drive belts to ensure maximum belt and bearing life.
How do you use a belt tension gauge?
Test machine place the gauge on the back of the belt. Not the rib side centering. It across the width of the belt. And as close as possible to the middle of the belt span.
How do I know if my V belt is worn out?
A correctly fitting V belt should slightly extend out of the pulley groove. If it extends out too high the belt may wear below the cord member. When a V belt rides below the edge of the groove this is usually a sign of a worn belt, worn pulley, or an incorrectly sized belt.
How do I keep my V belt from slipping?
There are additional adjustments you can make during installation and calibration to stop slipping:
- Install Lagging.
- Adjust Tension.
- Change Pulley Size or Change Out Worn Pulleys.
- Add a Snub Pulley.
What causes V belts to burn?
Belt slips, squeals (spin burn)
Spin burn can be cause by worn or damaged pulleys, and incorrect tensioning, which can wreak havoc on your belts causing damage and ultimately, premature failure.
How tight should a pulley belt be?
For most vehicles, the belt should not be able to be pressed down more than ½ inch. If it can be pressed lower, then the belt is too loose.

What causes V belt failure?
The most common reasons your belt could be missing a cog are excessive heat, the pulleys are too small or misaligned. It can also be caused by improper or prolonged storage of belts.
What is the most common cause of belt slippage?
Improper belt tension is the most common and obvious cause of slip, which generates unwanted heat. The friction that occurs when a V-belt slips in a pulley causes belt sidewalls to become glazed, and decreases gripping ability.
How do I soften my V belt?

What happens if engine belt is too tight?
If the belt is too tight, it will cause excessive side loads and overheat the bearings. This in turn causes noise, decreased output and even the seizing of the alternator. If the belt is too loose, it will cause the alternator to slip. This slipping can cause the alternator and the battery to work harder.
What is the shelf life of a V belt?
Normal Shelf Life of Belts
Belts should never be stored above 115°F. Belts will begin to degrade after 7 years even when stored properly. Beyond seven years, assuming normal storage, a decrease in service life of approximately 10% per year can be expected.
What causes V belts to break?
Missing cogs can cause belts to slip and fail, when it is discovered there are teeth missing, the belt should be changed immediately. The most common reasons your belt could be missing a cog are excessive heat, the pulleys are too small or misaligned. It can also be caused by improper or prolonged storage of belts.
What happens if your belt is to tight?
If a belt is too tight in a system, it can add stress to your bearings. The added stress to bearings can result into over amperage of your motor and potential motor failure. When a belt is too loose: When a belt sits loose on a pulley, the belt can slip while in motion and cause extra friction.

What can I use instead of a belt tensioner tool?
One then simply needs a long enough open end wrench (or spanner, if you prefer) and a jack. Simply jack the tensioner up until you can remove the belt.
When should I replace my V belt pulley?
As you tug on the belt to check for cracks, worn edges, and depth of grooves, you should also give the idler pulleys a spin. The belt should ride over the pulley without resistance. You can expect to replace the idler pulley between 50,000 and 100,000 miles.
Can I use wd40 as belt dressing?

What happens if the belt tension is less?
If a belt is not tensioned properly, it will ride too loose or too tight on the pulley. A belt that’s too loose on a pulley will cause slippage, which leads to heat build up from friction. This heat will damage your rubber belts and cause the belts to crack and break.
Why do V belts vibrate?
The most important operational and maintenance issue in a V-belt drive is its tension. If belts are too loose, they tend to vibrate, wear rapidly, and waste energy through slippage.

How long do V belts last?
V-Belts usually should be inspected for wear after 3 years or 30-40,000 miles of use. According to belt manufacturers, failure rates rise sharply after 3 years of service. Replacing V-belts every 3-4 years can minimize the risk of sudden belt failure.
What causes V belts to twist?
Cause: Pulley misalignment is a common cause of premature belt failure. Misalignment forces the belt to kink or twist while running, causing premature wear. Solution: Replace the belt and make sure to realign the pulleys. Also check that the pulleys, pulley brackets and shafts are not bent or broken.
