HOW IT WORKS is slightly different than I said on the video. After looking it over extensively, the thick spring inside only purpose it to dampen the blow from the belt turning the pulley to the alternator's resistance to turning. So this would reduce vibrations and extent belt life. The outside skinny spring is always binding outwards with the pulley; keeping it locked. So default is pulley locked. Reverse rotation coils up that smaller spring and reduces it's size, disengaging the pulley. I looked it over extensively off camera and I came to the conclusion these are dry assemblies. Any lubrication(other than bearing) would hinder it's operation.

Just a classic wrap spring clutch. This is not for MPG but because the engine can decelerate so fast in shifts, the alternator keeps driving the belt and all the belt renstiins reverse and you throw the belt or the belt squeaks at the shift point.

Replaced the alternator on our Dodge as the coupler went bad and it was $100 for the pulley and $160 for a lifetime alternator with the pulley. It's supposed to increase belt life, but the idlers died and destroyed the belt less than 5000 miles before that. It's supposed to help reduce rotating mass for shifts, but 3 idlers, a tensioner, water pump, power steering pump, AC compressor all tell me it's BS. Just another part to replace.

Diesel engines produce a very peaky output torque as each power stroke occurs - more that a gas engine at any rate. This means the actual crank speed rises and falls over the span of a single revolution and without the free-run clutch the same shock load would be fed to the serpentine (alternator) belt and to the spinning alternator. The clutch is designed to insulate the belt and attached devices from that short-term variation. I had one of these seize on a VW group diesel car and the first thing I knew about it was when the alternator support bracket casting cracked under the very peaky load...

Good to know. Good video. Great channel.

Love these repair videos. Auto parts have gotten so expensive. These days ppl hold on their cars longer. Pls more power tool repair videos. I want to know how to repair m18 fuel impact wrench gearbox and motor.

I'm workimg in the altenator and starter repair industry and advising every customer to step away from this type and with a simple trick find its INA (Volkswagen) equivalent, because the factory spiral pullies not even lasts 80,000 km in most cases, and I was tought by my senior car mechanic that the good parts must last minimum the altenators lifespan which is in general at 200,000 kilometers. The INA counterparts can last even more than 200k and are tenth of the price of factory pulleys. The replacement trick works very well, if you have a bunch of old ina brand pulleys as a comparison set, so you can place the spiral and INA roller type probe pullies side to side on a flat table outer face up and you can find the same pulley in height and diameter from the INA brand series if the shaft has the M16 thread on it. Then you look at the INA number on the face and can order a new INA pulley for the altenator. In many cases you can buy spacers under the pulley with the thickness of 0.5 or 1 mm or you can stack more up to reach the height of the old pulley, but avoid to use more than 3 mm because the pulley's centering bore step (facing inward) will not seat on the altenator shaft. Important thing is that you have to check the used thread lenght within the INA pulley, so it wont tie just on the tip of the shaft thread, then you can use it, otherwise you must find another INA geometry. 3 or more whole rotations from the thread beginning are the absolute minimum requirements for a strong mechanical fitment. About the factory spiral pulleys: these arent dry but filled with PTFE-like thermal grease and can not be repaired, in the video you can see at 6:48 that the grease dries and flies out with time and the internal shaft get severely worn down, so is with the white centering teflon rings, and even if you replace bearings, the pulley wont ever run centered anymore, and that could damage the entire drivetrain, tensioners, etc. Recenly the manufacturers began to use 14 mm threaded pullies (japaneese altenators mostly) using this terrible spiral spring type, these unfortunately can't be replaced with INA pullies, but in this case aftermarket ones can do the job if high price is deterring customers, but these chinese pulleys must be the last resort. INA uses its scary spline instert wrench, but if you repair the altenators everyday, its not a big thing to buy it, and this wrench desing works well too.

Mercedes Benz tech here. I've replaced a few alternators because of the one way clutch. I've only seen them on diesels and you can tell when they fail because the belt will chirp loudly at idle due to a diesels crankshaft speed fluctuating at idle. The one way clutch allows to pulley to slip during the rapid deceleration of crank speed as the next cylinder in the firing order is coming up on its compression stroke. Once the engine is off idle the belt doesn't chirp since the engine speed is more consistent.

I'm surprised how many shops replace the entire alternator. I guess they need to make money, but...

It reminds me of the clutches on an old OMC stern drive, which has one for forward and another for reverse. If you shift through neutral too quickly, the tang at the end of a spring would break and after that it just slips.

Decouplers were introduced due to the pulses of acceleration and deceleration of the crankshaft in a direct injection diesel engine. The snatch of the auxiliary belt could not be moderated by the tensioner and the alternator bearings were collapsing prematurely. The dual mass flywheel was developed for the same reason to smooth the power delivery into the transmission. Vehicles which had a solid flywheel conversion could run into problems with the 1st motion shaft bearing having excessive play and breaking up. Ball bearings and gears together does not end well....

When these came out on Dodge/Cummins they were supposed to cure belt squawk and wear upon shutdown. Apparently the crankshaft accelerated and decelerated sharply as it bumped over a few compressions after injectors cutoff.

Great job, I always wanted to do that. It makes sense that the pulley disengages when the engine suddenly decelerates, to allow the momentum of the alternator shaft to freewheel and get a tiny extra benefit from stacking electrons as the alternator momentum is converted to power. Does the engine and pulley on your car rotate clockwise as you stand facing the belt side of the engine? I'm assuming one spring will dampen the jerking force of positive acceleration, and the second spring disengages the clutch during deceleration. I'm a little unclear as to how the second mechanism works. In a patent I found online they describe a torsion spring and a clutch spring, wound in opposite directions. As you say below the clutch spring expands into gripping engagement when the pulley has more rotational torque than the hub. Then when the engine decelerates the hub becomes the source of rotational torque and the spring contracts, allowing freewheeling.

Not true and potentially unsafe advice not knowing the application. I had a one way clutch pulley which when it went bad it seized the clutch and acted like a solid pulley. It is noticeable chirping the belt, turning the car on, off and shifting. There are one way clutch, over running alternator decouplers and solid pulleys. This is a decoupler which also dampers shock to the other pulleys and components on the belt. On some cars if they had an OAD stock they may also have a different belt tensioner than had they been equipped with a solid pulley. These are on engines because on some the rotor in the alternator can over run the speed of the belt. Which then chirps causing wear and vibration in extreme conditions you can throw the belt. This was why ford added them only to the interceptor model crown victoria with the larger Mitsubishi alternator. It can like almost everything technically have an effect on fuel economy though that usually was not the reason they began becoming common place. It had more to do with vehicles using more electricity and having much more powerful alternators. Many factory alternators now are outputting what people with large audio systems used to need to upgrade to.

Do you think you could weld the inner and outer parts of the pulley to remove the clutch "function?"

I just replaced the clutched alternator on my 2004 Ford Focus, today (9/30/23), with a non-clutched alternator; because I didn't know the car had a clutched alternator. But, from what you're saying; the clutch is a piece of junk and doesn't really matter (which is what I figured out, after reading a few articles on them).

Can a overrunning pulley be retrofitted to an alternator that never had one.....I have a 2001 Dodge Ram V8 and it doesnt come with an OAD pulley.

I'm not sure about other applications but the 200 Amp Mitsubishi alternator on crown vic interceptor models the one way clutch or decoupling has nothing to do with fuel economy. With the rotor size and a standard pulley it can throw belts and chirps on shifts, startup and shut down. The decoupler over a one way clutch adds dampening which saves on the belt and the other components.

The 33-spline is not just WV, it's used by every European car manufacturer. Here you can find aftermarket pulleys for €50 for almost any car and for less than €30 for most cars. Some "premium" aftermarket brands are crazy expensive too and I've no idea about dealership prices. You can find the socket for only €5 if you can use an impact wrench, otherwise you will also need a torx bit to prevent the shaft from rotating and they are usually sold together in a kit starting at about €12

When you add up all of the complicated, prone-to-breakage, difficult and expensive to repair "fuel saving" features on a modern car, you'd probably need to drive it at least 750k miles to pay for the increased price of the car with that fuel savings, and replace every piece of that fuel -saving engineering wizardry along the way. But very few of these vehicles make it past 150-200k miles, so they need to be replaced with the latest tech wonders---at what cost to "the environment"? So this is where we are with transportation in 2023, after 60+ years of this Washington D.C. inspired bull excrement. Thanks for a job well done, you benevolent, omniscient Washington D.C. people. You've really delivered on all that money you've sucked out of us.

So hey. Let’s say I have an alternator and I’m certain that what I hear are shard of one of those rollers drifting throughout the internals as the pulley spins. What would have the best odds paying off for the longest: 1) removing the shards and assembling, or 2) leaving the shards and sending it?

This device is not about economy, (poly-v belt is) but for damping belt vibrations at idle that is hursh for those poly-v belts and noisy. Works only at idle and as a side effect on very rapid engine deceleration like when using the brakes. Actually does reduce idling noises and extends belt life.

Yes, the spring is called a Bendix clutch.

I agree Mo…the minuscule amount of gas savings wouldn’t anywhere near pay for the life of that design. That coupler has more parts than a piano…but as rusty and dry as it looks the bearing suffered from immense heat from its related components not getting any type of lube- lotsa dry friction.

I knew those alternators could be fixed and it doesn't look too difficult for even the tool inclined to fix either

The purpose is to keep the engine from spinning the alternator to fast because until recently when turbo engines took off the engine hardly ever got above about 5k rpms now with them turning 7 & 8k the decoupler disengages around 4500 keeping the alternator alive

weld it up and go on with your day.

Logically I see no reason why it would be a bad idea, but I have searched high and low and even tried emailing the Litens Automotive Group (owner of the patent on the OAD pulley) to ask, but they never replied. I need to replace my alternator pulley and I have a 5-speed manual transmission, and I'd love to have the benefits that come from an OAD pulley, but nervous about trying this upgrade until someone more knowledgeable than me confirms it can't hurt anything.

The benefits are minute. These have a high failure rate and will likely leave you stranded. They were originally designed just for diesel engines. This is because when a diesel engine shuts down it's very abrupt and the belt would chirp. This is not ideal when you're trying to sell a new car that has belt squeal/chirp.

The way that works was very interesting, thanks for showing us. The one on my VW locked up at about 150k miles. Since the alternator was still working, I drove it another 200k miles before the it stopped charging the battery. I then just replaced the whole thing. I have put 100k miles on the replacement alternator, so it might be near the end of its' life. At least I now know how to fix the clutch if it dies. Ginger is as cute as ever, we need more Ginger. 😊👍

2002 jetta wagon, 450k miles, ALH engine with manual transmission. Other than normal maintenance, like tires, batteries, and glow plugs, the only things that have been replaced on the engine are the a/c compressor and the alternator.

I just encountered my first one with this stupid concept on a dodge journey. Didn't notice or check clutch when OG alt failed on lady's car. 2 weeks and I get a call they are stranded. Discovered weird clutch thing issue as removed it.the rebuilt orileys failed in 2 weeks. 2nd one failed in 10 minutes. Hope 3rd lasts because I got screwed on labor.

I thought they were used on diesels to stop belt squeak when the motor shut off.

Can you add these pulleys to normal alternators, could there be any benefits?

Yes, they're swappable. If you had something like a 10-speed transmission, you might see a gain of 1% fuel mileage. That would be city driving. Highway driving you wouldn't see anything. So if you got 15 MPG City you would get 15.15mpg possibly. I guess they were originally invented for small 4 cylinder diesels. Diesels when they shut down because of such high compression abruptly stop unlike gas that coast. This abrupt stopped can cause the alternator belt to chirp. This obviously would be a concern from consumers on a brand new car.

What engineer was out riding a BMX and had the idea to incorporate a freewheel sprocket into vehicles ?
