p.s. There are some BRP & ALH motors that have non clutched Alternators  :wink:


if that's the case, that would explain the ALH failure i've seen.  those engines even have a smaller machined end for a quicker crank pulley death.

Unlike other spots on the web the idea here is to check the ego at the door and learn from each other, regardless of background.  None of us work for VW as engine designers so everyone's opinion is just that... an opinion, and a valid one... when expressed respectfully.

Everyone has a perspective... some may be closer to the truth than others... but in the end we're here to learn from each other.  I'd respectfully ask that we all take the tone of this particular thread down a notch, recognize that there are many many ways to interpolate what was on the mind of those wacky VW designers, and carry on learning from each other.

'Nuff said... back to the discussion.:wink:


Well said.   Thank you for the reminder Obi-wan :wink:

Well, you missed the ones that AutohausAZ.com is selling NEW for $65.   :wink:   :lol:

Not really.As I have stated above we have seen failures on everything clutch and non clutch related.Again it is your choice to take whatever information you deem necessary from this thread and learn from it but if it was me I would double pin the crank snout before I change my alternator pulley.

The Keyway is in the crank sprocket itself, not the serpentine pulley.

That being said, yes the crank serp pulley shown is not what is typically found on the AAZ.  Here is a pic of the typical pulley:

Regardless, I don't see how the pulley design would have any effect at all on the failure.

Ah right.  Sorry about that.  :)  Still, the serp pulley that Ashley posted looks like it might weigh a lot less than the AAZ pulley- with more substantial dampening.  If that's the case, then I do think the serp pulley design would play a part in keyway failure.  Maybe the dampening is there not to reduce harmonics from the engine (since v-belt VW's didn't have them) but instead to reduce pulsing from the serpentine accessories?

HOLY CRAP GUY'S  :?

I agree with Vince, lets all leave our ego's at the door.

this being said, it is my opinion that you are all right... VAG has acknowledged the problem and has put forth what they believe will fix it in some cases.

I for one will be doing the clutched pulley upgrade but now I am also interested in a more efficient Harmonic balancer ( thanks Wizard )as I will be building a high HP AAZ.

Weather you are an engineer, professional mechanic or just a shadetree mechanic like myself we can all be right on points and sometimes be not so right, but I think all the cases argued in this thread are VALID and can be addressed in different manners.

now can we give this thread back to Ashley? who will have a good looking setup going  :lol:

Ok I've been following this issue for years (I suffered a crank nose failure on my AAZ, super fun times...) and upgraded my motor to a TDi crank & pulley setup but kept the solid pulley because I thought I was safe.

So even with my tdi crank should I be looking for a clutched alt pulley? I've been told they can corrode & seize by a vw mech who replaces them often for that reason...fyi, although this group would probably be better at noticing that happening than the average driver I suspect.

Does anyone have a drawing that a machine shop could use to modify cranks out of car? Andrew you're too far away & I have a mate looking into moding his.

Good exchange BTW boys!!

There was some chatter in the 2006-2007 era over on tdiclub about the clutched pulleys failing catastrophically (ie flying apart) as opposed to simply seizing, but the belief is that this was a earlier version of the pulley... a new design (and part number, iirc) was released and I've not seen any recent reports of unusual pulley failure... either seized or in pieces all over the highway. :wink:

So all tdi's even after the crank nose change came/come with a clutched pulley now?

Anyone hear of failures after the crank node change was made??

whoa, apparently this thread blew up when i wasn't looking...


Quote from: "wizard-of-od"
Ok Ashley as made me aware of this thread as you guys are scaring her a little too much....


first off, no one scared me about anything.

i was just alittle confused why a "great" seller like INA (wizard of od) was posting this set up all over the diesel forums without mentioning that it would still cause crank failure.

secondly, his customer service abilities make me question his mechanic abilities or even knowledge.

now, i know you and me patched things up and yes you do have great prices on most items. but to be honestly i'm alittle weary to buy anything else from you right now until proven wrong. in my opinion if i was running a business and had messed up and also made a customer unhappy by thread jacking her post [on vortex], i would have sent out the right spacer right away and let her keep the old one and gave a discount on the belt too. but that's just me.

as for this cranknose failure issue, i am putting the car together the way it is and if in some crazy case it does fail, turbo diesel here i come.

thank you though, everyone for your help in all this.

The fact that one of the participants in this discussion has a vested commercial interest in the outcome is new information... cool !! :wink:

Have at 'er Ashley and let us know how it works... it's a tidy setup for sure... torque the crank sprocket as per spec and Bob's your uncle!
