How to Test and Replace an Alternator Clutch Pulley - YouTube.

The easiest way is to use the cooling fins on the opposite side. Carefully insert a screwdriver so that it prevents the cooling fins from spinning. Once you have done that it is time to test the pulley. First, rotate the pulley clockwise. The pulley should ** NOT** be able to move as it is locked to the alternator which has been held up by the. 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. If you are wondering about your alternator pulley, there is an easy test. Remove serpentine belt. Carefully stick a screw driver into the cooling fan to hold the internals still. Rotate the pulley - it should freewheel in one direction and lock up in the other.

SOLVED: Alternator pulley not turning, belt is tight, not.

An alternator charges the battery while the vehicle is running by turning mechanical energy from a spinning pulley into current. The rotor, brushes and other internal parts of an alternator wear out over time, so replacing it is something everyone eventually needs to do. The following symptoms should give you an idea of what's gone wrong, but.

The stock pulleys are roughly 8" drive and 3" alternator - 2.66:1 so at 6500 redline the alternator is spinning at 17300 RPM STOCK. The 3.2 pulley will yield 16250 RPM. A difference, but not a massive change. I am not sure where the upper RPM design limit is on the alternator. The only pulleys you should be able to turn by hand when the serpentine belt is not in place are: the water pump, alternator, and power steering pump pulleys. The air conditioning compressor has a clutch on it that should spin freely as well but it will not be rotating the internals of the compressor. Where as right now it’s spinning slower then a stock 5.0 car or a 93 cobra car with the 93 water pump pulley and a 4.6 under driven acc drive blower pulley at idle. The alternator must be addressed as well because at 7200rpm if I didn’t change the pulley it will be on fire at close to 20k rpm with the current 94-95 pulley.

Lower alternator pulley/nut/washer | The Diesel Stop.

If the internal clutch mechanism is bad, the pulley may slip and fail to drive the alternator, or it may remain locked all the time – increasing noise, vibration and stress on the belt drive system. Advertisement Another type of special pulley is an Overrunning Alternator Decoupler (OAD). 2. Alternator pulleys do not have a key and should be a slip fit. sometime thread locking. needed to remove the pulley, do not overheat. Install the new pulley, lock washer, and nut by hand. 3. Tighten the nut with an impact wrench until nut is tight (about 70 ft-lbs). The lock washer must be completely closed. The alternator pulley is way too short and the belt will not line up. the red arrow shows the first pulley, which looks the same as the one on my Driver engine. What i need to know is would i get away with fitting my Drivers water pump as the pulley is shorter and then using the rear pulley closest to the engine.

Alternator Pulley Removal????? | The Truck Stop.

An alternator pulley is a device that allows a vehicle's alternator to be turned by a belt, which is driven off of the engine's accessory drive system. Commonly made from stamped steel or cast aluminum, an alternator pulley is either grooved for use with a V-type fan belt or designed with multiple grooves to be used with a serpentine-style. 1 the pulley will slip and items like the alternator will not charge properly and 2 and this is the most likely to happen the pulley section will part ways with the crank section and damage the radiator and other parts of the engine before it hits the ground and damages items nearby.

#1 BLUEBLOTCH Proven Member 810 1 Apr 30, 2004 Amarillo, Texas I put a new alternator belt on my GS-T after the belt broke and The belt wont spin. Both Alternator and Crank pulleys spin freely by hand but wont spin when the car is started. Could this be crank pulley seperation? Everything is in order with the car. TIA! Jul 22, 2006 #2 Defiant. Check the large power cable to the alternator and the fuse, usually, a large 40-60 amp fuse near the battery. Check the ground cable between the engine and the body. Check the serpentine belt and make sure the alternator is spinning with the engine. Check the small power supply wire and the charging light wire. This means that you could have a weak alternator, or a poor connection at the battery terminals. You could also have a loose drive belt, which is what supplies power to the alternator itself. If the drive belt is loose or not working properly, the alternator will not charge. Loud Noises.

Alternator pulley not spinning? is it normal | Acura RSX, ILX and Honda.

An alternator pulley is powered by the serpentine belt to run the alternator and create charge. An overrunning alternator pulley, or OAP, allows the belt to turn the alternator in one direction using a one-way clutch inside the hub. This also allows the alternator to spin at its own speed when the engine is decelerating. At 6,500 rpms you are now spinning the alternator at 19,500 rpms, seriously over spun. If you install, for example, a 3.2 inch alternator pulley, this will now produce an alternator speed of around 2x the engine speed. Alternator idle speed is now dropped to 1600 rpms and the 6,500 rpm engine speed has now dropped the alternator down to 13,000.

How to Troubleshoot a Noisy Alternator - OnAllCylinders.

"Why would an alternator pulley turn freely by hand and not turn when the belt is on and the engine is running?" 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.

Alternator Noise: How to Diagnose and Fix - Better Soundproofing.

Pulled the alternator, replaced the brushes/regulator as they were pretty well worn, but not completely. Re-fitted alternator, still no charge and loud knocking sound, but definitely from the alternator area. No issues I could tell with the pulley/bearings when spinning by hand. Pulled it again and took it to alternator shop. 9. 3. 14. Oct 2, 2013. #2. They are just a 5/8 course thread nut 15/16 socket to install but there only about half a thick as a regular nut and yes there is a lock wash that need to be put back on to keep it from backing off again. I just put new under drive pulleys on mine tonight. Sent from my iPhone using Tapatalk - now Free.

It is impractical to replace the bearings in these units because it calls for special tools and equipment that its not cost effective to buy. If the water pump is bad a new one can be had for less than $30. Crank pulley failure is a common issue on MINI Coopers built between 2002 and 2006 and with a mileage above 75,000. Crank pulley failure refers to the pulley connected to the crankshaft that drives the belt responsible for the alternator, A/C compressor, water pump, and supercharger (on "S" models). Below is an example of a broken pulley. The "overrunning alternator pulleys", also called "Sprag clutches" in other applications, are a beneficial improvement. The alternator is spinning at nearly 20,000 rpm when the engine is at full throttle and shifts from 1st to 2nd. This is more than a 1500rpm engine speed change..... Resulting in a a 5,000 rpm alternator change in less than 1.

Reduced crank and alternator pulleys - MiniT.

If your alternator pulley won't spin, it doesn't necessarily mean the alternator is bad. You might be surprised how easy it is to clean it up and get everyth. 1rst: spun the alternator pulley, spun to the right, takes about 4 seconds to stop and there is a lil whisp/whine noise when it spins. Spun to the left, no noise but and not much spin due to it being a clutch pulley.-2nd: spun the water pump pulley, there is no free spin and it only takes about 2-3 seconds to stop spinning in each direction. It sounds as if the pulley may have seized (pretty rare) then snapped under load. You probably need a new (or used) alternator. 2000 V70R Black, 144,000 miles Wife's R. 2007 V70 2.5T White/Oak 111,000 MILES.

Do alternators have clutches? Many late-model vehicles do not use a solid alternator pulley.... An Overrunning Alternator Pulley (OAP) has a one-way clutch. MW67RS. I put a CS130 alternator on my new engine. I am using a V-belt with modified stock brackets and stock pulleys. I started the engine and the alternator worked. It provided 14V. But the belt was throwing off rubber shavings. I replaced the alternator pulley and belt. It is still throwing off rubber shavings but not as much as before.
