    Great video !! I replaced the pulley the first time but paid the mechanic $20 to swap it out as I brought him the alternator and pulley. I was happy. This time... I bought the tool and the pulley. Video is great and so true about the noise that is made when the pulley is bad. The first time I thought my tensioner was bad as you stated. LOL Thanks again.

Po obejzeniu twojego wyjasnienia doszedlem do wniosku ze mozna to naprawic wymieniajac tylko pullej na nowy a nie caly alternator. Bo mysle ze to bylo przyczyna choinki na desce rozdzielczej :) Thank you for your help mate

    Great video Mike. Was about to order a new power sterring pump as I assumed wrongly that was the culprit. Symptoms you describe (noisy rattle accompanied with flapping belt) match exactly what I'm hearing on my 2001 TDI passat. Its also done 73,000 which seems to align with the espected service life of the alternator pulley. Will be ordering a new pulley and pulley removal tool off interent. Thanks again.

    NVM, it's a deceleration coupler clutch. Used for torque control and to relieve the stress on the drive belt system. Actually it's an ingenious design. Reduces noise, belt tension from the alternator, and torque control.

    A seized alternator pulley caused a chain reaction of damage on my TDI.
    The added force of the alternator decelerating and the belt driven components receiving more stress, it caused my crankshaft timing gear to move and bent the valves in the engine.
    I wish I knew about these clutched pulleys short lifespan, it would have saved me lots of money in repairs.

      That is fascinating. Thanks for posting. The pulley came off of the alternator this morning on my EuroVan (with a 1.9L TDI). Wasn't able to find it, but the shaft is okay. Assuming it must have seized up. I installed it a little over three years ago, an upgrade from the solid pulley that was on there. It appears that the OE INA brand pulley is discontinued for my particular setup, but Gates and Hella still seem to produce them. I've ordered both. I think the original INA pulley I installed had seen about 60,000 miles.

      Make sure to check/replace your crankshaft timing sprocket when you do your next timing belt.

  • @WestronicsIrl

    Hello Donna,
    If the noises are irregular it is more then likely the clutch pulley.
    Consequence of driving like that are quite severe.
    The pulley will fall off and destroy the shaft on the alternator,which means that you might need a new one.
    Better get that checked.

  • @WestronicsIrl
    @WestronicsIrl  11 років тому

    Hello there,
    If you have a Valeo alternator it could be it,windings in the rotor use to go in them and that will cause the engine to shake badly.
    But there is a plethora of different things that can also cause it,worn engine mounts,worn crankshaft rubber pulley etc.

  • @WestronicsIrl
    @WestronicsIrl  12 років тому

    Hello mate,
    Your alternator is a popular denso type and it has a clutch pulley.
    Noise that you are talking about can be caused by either the clutch pulely or the bearings in the alternator.
    Both of them are easy to check,just take the belt of the alternator and give it a spin with your hand.
    That should give you a fair idea are the bearings quiet,if they are it means that it has to be the clutch pulley.

  • @spannerssockets6308

  • @WestronicsIrl
    @WestronicsIrl  12 років тому

    Hello mate,
    If you took the belt off,and all 2 bolts out of it it should come out.
    If it doesn't just use a large screw driver as a leaver and leaver it up from the side.
    Just make sure you are not supporting the screw driver on anything plastic.
    It should come up easily then,there is always bit of a force required with those ones :D.

  • @MikkoRantalainen
    @MikkoRantalainen 2 роки тому

    We had (nearly?) frozen pulley and it resulted in belt flapping and pulley breaking down. Luckily it stayed in place tilted and the belt dropped from the tensioner and didn't break anything. The tensioner was able to keep the belt strict enough to not cause noise, though.
    Of course, I didn't know that the belt flapping was a clear sign for frozen pulley. After replacing the alternator the belt goes smoothly so the tensioner didn't get damaged.

    And if your clutch pulley siezes solid,the automatic tensioner jumps like mad,because it starts douing what clutch pulley should do,which is
    Taking the kinetic force of the "strech-destrech motion" away.
    Question 2)
    -Most cars manufactured after year 2000 have a clutch pulleys on them,
    mostly they are diesel engines that the clutch pulley is used (not sure why but i think its due to the fact that diesel engines have more torque than petrol,so there is more forces working on the fan belt.

    No apparent sign of wear marks on the casing. New tensioner and idler pulley have been fitted but the belt is flapping on tick over sounds awful.
    I am pretty sure it's a problem with the pulley would your locking test apply to the megane i.e locking armature results in pulley moving both directions or pulley is locked in both directions indicates a defective clutch pulley?

  • @WestronicsIrl
    @WestronicsIrl  12 років тому

    Famous is right,
    Ones on the megane are a bit diffrent,they are a big aluminium lump of a thing.
    The best of knowing if it is worn out is to have a look at the casing of the alternator,
    when them pulleys wear they will go sideways a bit and rub of the casing of the alternator.
    If you can see that your pulley have rubbed of a bit of the alternator it means thet it have to be replaced,alltho the symptoms of these pulleys going be the same like in the video.

    Howdy,great questions here.
    1) Need for clutch pulley:
    They are used because in modern cars "fan belts" are much longer than they used to be.And as you might not know when the engine is idling its motion its not smooth,the revs go up and down thousands of times per minute (every time there is a combustion in a chamber the fan belt gets a little "pull").
    Due to this the fan belt streches an destreches thousands times per minute,

    • @davidparker9676
      @davidparker9676 3 роки тому

      It is because the old V-belts slipped under the same stress. With the new serpentine multi-groove belts, they don't slip and transfer all of the stress to the other components.

    Not at all,there are two options,in some models alternator just comes off after removing two main bolts,plug wire,and main positive wire.
    In other models underneath the alternator there is a bolt with a hexagon key which holds the viscous fan,which is in the way sometimes.
    One way or another you never have to remove a bumper and all the rest of it.
    Hope this helps.

    However, the auxiliary belt is screeching like mad when the steering is on full lock. I have been told that the most probable cause is a defective alternator/clutch pulley. I was also to the way to check the pulley was - its just a ratchet,should turn one way and free wheel the other.
    My new pulley did not do this, so do I have a faulty new pulley?

A/c is working perfectly fine. Thanks in advance
