Can you over tighten a tensioner pulley?
A belt shouldn’t be over-tightened
. Any bearing that the belt rotates on can be burned out by an over-tightened belt. A pulley bearing can be ruined by an over-tightened timing belt.
How tight should a tensioner pulley be?
Can a tensioner be too tight?
If a pulley on one of the accessories seizes or fails to turn it will likely destroy the serpentine belt, but it’s important to consider that
a belt that’s too tight will often lead to seizing pulleys
. You will need to remove the belt to replace the damaged accessories or pulleys if one fails.
Do you tighten or loosen a tensioner pulley?
Can you tighten alternator belt too much?
An over-tightened belt can burn out any bearing that the belt rotates on
, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.
Is the tensioner pulley supposed to move?
The tensioner arm should move smoothly and freely
. Solution: If you notice a binding, sticking or grinding tensioner arm, the tensioner should be replaced.
What happens if your belt tensioner 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 happens if you over tighten a timing belt?
If the timing belt is too tight,
it could wear out the bearings in your engine and potentially cause your belt to snap
. Here are a few warning signs that could indicate that you have tightened too far on your timing belt: Engine sounds louder, usually with a whirring, knocking, or droning noise.
What can happen if timing belt is too tight?
If the timing belt is insufficiently tense, there is a danger that it will ping off. If it is too tight,
all of the bearings will be stressed
, which is definitely also a bad thing. You’ll notice this thanks to the loud running noise. In the worst-case scenario, the belt can even snap.
How do you reset a pulley tensioner?
How tight should drive belts be?
For most vehicles,
the belt should not be able to be pressed down more than 1⁄2 inch
. If it can be pressed lower, then the belt is too loose. Note: Manufacturers have their own specifications for how much deflection can be found in the belt.
How much play should a serpentine belt have?
if you are squealing from the bearings it is TO tight lol. but yes about
1/2′′ of wiggle
. and no matter how hard you push or pull the belt will only stretch so much lol so 1/2′′ is pretty accurate.
What is the general rule for tightening a belt on a pulley driven system?
“
Press the belt with your thumb until it deflects about 1/2 in
.” “Tension the drive until you get a slight bow in the slack side when it is running.” These old rules of thumb for drive tensioning have outlived their usefulness: It is time to abandon them.
How do you align a tensioner pulley?
How do you test a tensioner pulley?
Is the belt tensioner supposed to spin?
Spin the pulley to see if it spins freely
. If you hear grinding or the pulley doesn’t spin freely, replace the tensioner. When you replace the belt, it should take a lot of muscle power to move the tensioner. If you can move it easily, the spring tension is most likely not tight enough.
How do I know if my timing belt is tight enough?
How do you tighten a timing belt tensioner pulley?
Do you have to bleed a timing belt tensioner?
If the tensioner/actuator is affected by the “sponge state” then a bleed out procedure is required
and failure to do so can lead to the timing belt jumping teeth causing expensive engine damage.
How do you compress a tensioner?
Can a belt tensioner making noise?
One of the most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner
. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started.
How do I know if my serpentine belt is too loose?
A loose drive belt will often be
noisy, squeaking a bit, or emitting a high-pitched squeal
. The most obvious sign of a loose drive belt, though, is in its appearance and tension. A loose belt, simply stated, looks and feels loose.
How do you check belt tension and pulley alignment?
- Switch the input power OFF and unplug. the power cord.
- Remove the front hood.
- Verify the drive belt alignment. Make sure that the drive belt is aligned parallel to the frame rail. Measure the belt to frame rail distance at the drive roller pulley and at the drive motor pulley.
What happens if pulleys are not aligned?
When pulleys are not aligned properly,
additional loads are induced
. The aim of belt alignment is to align the grooves of the drive and driven pulleys so that the belts run with minimal wear. Proper alignment extends the service life of belts and bearings, reduces vibration and noise levels, and saves energy.
How do I know if my pulley is aligned?
What noise will a belt make if the pulley is misaligned?
A
chirping noise that increases in frequency as the engine is revved up
can be the result of belt vibration caused by misaligned pulleys. In fact most cases of belt noise are caused by misaligned pulleys and belts.
How do you tighten a timing belt tensioner pulley?
To even out the tension in the belt, use a spanner or socket wrench on the crankshaft-pulley bolt and turn the crankshaft two full turns clockwise . Tighten the locking bolt first to hold the tensioner in its new position. Tighten the pivot-spring bolt, which has a precise torque setting.
