What is the difference between OAP and OAD??? Can we see the difference with eyes??? Can we replace an OAP pulley with an OAD pulley????

You: "There is no real way that it can come undone on the car" My car: "I found a real way that it can come undone while my owner drives me. Extra: the half of the tensioner roller vanished, the belt of course is now open." Haha, so probably the freewheel function has gone and the pulley become a simple nut. Volvo V70 diesel 2002 @ 380000 miles. Thanks for your video, now I understand better the insights and now I know what waits for me tomorrow. An interesting addition: that morning I heard some "grasshopper" from the engine, I localized that it is the generator pulley, which traveled towards the generator first and touched it a little bit and started to make small chips, like on a lathe. I had no clue what was happening, so I went to the job, but I put 2 extra batteries into the baggage room and a start cable for every case (have some experience) . After 1 hour happened what I didn't want to happen, I prayed I can drive one hour more with the extra battery without a generator. (the battery in the car of course is near the end of life). I bought a better battery charger, so I could drive home the next day with 2 fully charged (1.5) batteries (approx 150Ah total), 2.5-3 hours, no headlights, and a few stops/engine starts.

Yep. My tensioner was rattling like crazy and my belt warped and twisted when idling. I took the belt off and noticed a crack on the belt. I checked all the pullies including the OAP by sticking a screwdriver between the fan blades in the alternator and trying to turn the pully both ways. It locked both ways. It's gone. $98AUD for a new OAP that I install myself. I learnt how to do it from youtube hahaha. I can fix most things on my cars because of youtube.

I changed the pulley on my -08 Toyota Auris yesterday. I bought a 14 pieces pulley tool set from my local partstore, but non of the bits fitted. It had like a 17mm insex with a 12 or 13mm boltend on middleaxle. I just drilled down the bolthead so the 17mm insexbit fitted and simply used my Milwuakee M14 fuel to loosen it. Worked great!

This is exactly what happened in my car. Firstly it was the tensioner went bad. Replaced it with together with the belt and then surprisingly new tensioner vibrates. After that I replaced my water pump pulley because it sounds squeaking. In the process I also found the timing belt is due replacing too. After all that, tensioner still vibrates and I'm just stumped. The tricky thing about the OAP is that they don't really show any sign or symptoms of going bad. It only manifests its malfunction in other parts.

When mine went it would make a really loud screeching noise like like dry metal to metal, it started of as what sounded like a bit of belt screech then one morning the thing didnt stop screeching untill i got to the end of the road, i pulled over and took the cap off and started it up it would screech intermittently and you could clealy see the pully spinning a lot faster than the inner spindle, mine just lost its ability to grip to bring the alternator up to correct speed, its was a weird drive to the engine would pulse away with randam battey lights, mine has a vacuum pump on as well so it was also playing havoc with the brakes and turbo

My advice is to use an impact wrench to get the pulley off of the alternator. The pulley is bad anyway so you don't have to worry about ruining it. Use the proper tools to get the pulley back on the alternator and torque it down to the proper torque. Using an impact wrench on the new pulley could damage it. Trying to use the 31 tooth pulley with the center allen wrench tool to get the pulley off could break the allen wrench.

😢I just broke those thing that need M10 with 12 points but I used T50 bit 6 points so I had no choice than to remove the alternator out and there is no way than to use “ electric Wrench / IMPACT with spline 33 “, It’s done no more than 3s, Wondering why didn’t I use this method than by those manual tools it’s so hard like hell ( I’m not a mechanic) Then I put a new INA (OAP) pulley back but I cannot use any Torque wrench either, so I shot twice with electric Wrench impact twice a second each with hope just close to torque value without break the new pulley, DONE ! I believe by running the car it will help to torque themselves 😂to the value 85NM* It seems now is running fine without “clang weird noise “. I did replace the pulley because even after replacing the Tensioner, the weird noises and the tensioner was goggling too, the most culprit was the seized pulley’s 😂solid no clutch! IF you don’t have any experience like me to do this but you have to, remove the alternator from the car, check the right tool for… Or just use electric impact that we use for replacing wheels with spline, a second done ! Lesson to be learned 😅 Good vid, thanks

Well sure if it's completely shot and spinning free but that's unusual, normally they seize up and behave like a solid pulley while making weird noises. You need to to diagnose your alternator system and check it is the alternator to begin with. Try kzbin.info/www/bejne/h2OkcoCZbrt8g9E

No, it requires a decent impact gun, do you just want to replace the pulley? To do timing you need the right tools. Stories on talkford.com are worth reading over, e.g. talkford.com/community/topic/158267-crankshaft-pulley-removal/

I don't understand how the shop used an impact wrench to drive the splined socket with the hex nut tool in place. It's a pick you couldn't watch them undo it. I wonder if the held the splined socket as you did with a ring spanner in a vice and used the impact wrench on the hex bolt?

The point of an impact wrench is it hammers the fitting with such high but transient force that you don't need to hold the other part. The alternator has more than enough inertia.

The main reason for the pulley has to do with the engine... modern gasoline & diesel engines can have multiple "ignition firings" (per cylinder) which cause multiple power pulses through the timing chain / belt and serpentine belt (per cylinder firing). Clutch pulleys help absorb these pulses because the alternator is able to continue to spin, rather than slow down & speed back up with those pulses. Power steering pumps, water pumps, AC compressors, don't have a heavy "rotating core" like the alternator... so there's no need for them needing a clutch pulley.
