Alternator pulley / freewheel clutch on Volvo XC70 D4 - YouTube.

Most all of the '00-'02 330's came with the Bosch 120 Amp alternator (and that is all I have tested this on), which is the same alternator used in the VW diesels. The INA part number is #022 903119C. The stock pulley weighs 9oz. and has a 50mm diameter. Turner under drive pulley weighs 1oz. and has a 58mm diameter. The alternator rotor and shaft is typically about 90% of the weight of the alternator, so for ours it would be about 8-10 lbs of mass spinning at roughly 3x crank speed due to pulley ratio! That's a lot of energy to slow down each time you want to change gear. To calculate the actual alternator RPM, determine the ratio between the two pulley diameters. Ratio = Crankshaft Pulley Diameter/ Alternator Pulley Diameter Now that we know the ratio, we can now determine the rotor speed: Rotor RPM = Pulley Ratio x Engine Speed (example; 2.1 x 870 = 1827 Rotor RPM) Tech Tip.

FAQ's Alternator Questions.

Feb 10, 2003 · i current have a 2.93 i get a 2 lb lower pulley (the kit w/ the idler relocation thing), will it hurt my alternator or anything else? i'm considering getting it, but don't want to "hurt" the blower or alernator. thanks. The bearings in the alternator feel ok when I spin the pulley forwards, but if I spin it backwards the clutch pulley makes a loud screech.... replaced the idler and checked all the pulleys and they all spin freely. Just not sure how to test the clutch itself and dont want it to die on me on my next trip. Cheers Paul. 2014 GU Patrol ST 3.0 Auto.

If the pulley on the alternator stops spinning will replacing….

The alternator spins currently with no apparent resistence, and the pulley bearings aren't so tight that I can't move them.

There are two ways to fix a loose alternator pulley, here we are going to discuss both briefly: You can tighten the pulling nut with a 15/16 pass through socket, using a torque wrench with a 5/16 hex head socket secure the pulley nut so it does not move. The rotor shaft has to be tightened to 95 to 108 N-m or 70 to 80 lb. ft. 1. unless you use pulleys to change the speed, it still will not get to a decent speed. 2. You will need a method to cut power to the field coil when you are not moving, otherwise it will slowly drain the battery. 3. The alt will be mounted right where it can get splashed, or damaged by objects kicked up by the tires. SuperBurban Administrator.

Symptoms of a Bad or Failing Idler Pulley - YourMechanic.

Without actually examing the alternator first-hand, it sounds like the bearings that support the rotor (the shaft that spins within the alternator) may be failing, resulting in excessive drag when the tension of the belt is applied, thus preventing the rotor from spinning. ==== Update: 12/2/2018 ==== Continue Reading Quora User. Apr 11, 2009 · Customer Yes, replacing the alternator will fix the problem. I would inspect the pulley when you remove it and make sure it's reusable. If it's just discolored and no damage is detected, you can reuse it. I would recommend replacing the belt though. It probably is glazed due to overheating. Hope this answers your question and the info was helpful. So, to spin your alternator 66% faster at the same engine speed, you need either a 66% smaller alt pulley, a 66% larger crank pulley, or a combination of decreasing alt and increasing crank pulleys that total 66% Remember, if you have a too-small pulley on the crank as it is - you are underdriving your alternator already.

Over-running alternator clutch pulley install and info.

We charge at 17.8. To me, it just sounds like your clipping all around. Low voltage or not. EDIT- the smell gets stronger when the driver is not moving maybe, due to it not cooling, and just letting off heat. With it wanging, its cooling, (as it should) and the smell is there, just not as strong with it getting blown out the port, and moving. The drive belt system runs around it, providing a means for the crankshaft to spin the alternator rotor. As long as the pulley rotates, electric power is produced in the stator coils. The older vehicles have a simple belt that ran from the alternator to the crankshaft pulleys. The modern ones feature a serpentine or drive belt. 6. Housing. Therefore, the crankshaft and alternator are able to rotate together by the alternator pulley. If you didn't have this pulley, then the alternator would not be able to do its job. Loose Alternator Belt Symptoms 1) Flickering/Dimming Lights 2) Vehicle Stalls 3) Battery Warning Light 4) Chirping or Squealing Noise 5) Dead Battery.

The larger alternator on the TDCi makes the problem worse. When you slow the engine speed when driving or when you switch the engine off the clutch pulley works like a ratchet and let's the alternator spin without spinning its pulley, a bit like on a pedal bike when you stop peddling but keep rolling. I'm convinced its why the Mk3 eats tensioners.

Alternator pulley not spinning.

Underdrive pulleys use less power since they will spin the accessory at lower speeds. Overdrive pulleys will use more power and spin faster. The best one for you will depend on the requirements of your accessories, including your alternator and power steering. If you're serious about automobiles, you need to learn more about overdrive and. Jan 11, 2008 · Alternator will essentially not spin at all by hand freely, the belt was slipping and howling over it.

I had done a timing belt 2 years / 12k back and everything had been smooth since then.

Edc/ alternator pulley stops spinning please help | S-10 Forum.

The alternator pulley won't increase the speed of the supercharger it's to stop the alternator over spinning hence why it's 5% larger 2% crank pulley with the 17% pulley on the charger will be equivalent to 19% so IAT will be high, if I were you I would stick to 17% and standard size crank pulley unless you are running meth to keep on top of the temps. What causes pulleys to stop spinning? In most cases, the water pump is binding up, causing the pulley to stop spinning. Replacement of the water pump will fix your problem. The pulley will need to be replaced if there is damage from the belt on it. If there is no damage, then the pulley can be reused. Do all engines have a harmonic balancer?.

Next tried spinning Alternator pulley both ways with rotor jammed with a screwdriver and the pulley is solid in both directions, no slip in the reverse direction. Pretty sure it's the free-wheeling type of pulley because it has a plastic cap covering the middle of it. So seized and the noise it makes is exactly as described by a UTube video on.
