- This is our DIY showing how to replace your Crank Pulley on an Audi 3.0T. On a C7, you may not have to use service position to do this job if you have the right tools, but it does make the job a lot easier. If you want to learn how to put your car into service position, look in the links below for our video on it.
I replaced my 187mm crank pulley with a Velocity AP 205mm oversized crank pulley to achieve a Dual Pulley ratio and finally go dual pulley on my car.
Let me know what you think of the video in the comments!

Super informative, as a first timer dealing with a crank pulley it’s very helpful when you take the extra mins to explain briefly, thank you
Thanks man!
Attention! A note about the drive belt diagrams in this video:
In this video I show a screen shot of a belt diagram for the drive belt, and it includes routing around a Servo Pump Pulley. That does not exist on this engine. I'm researching to find out if that is a specific option or if that is on another kind of 3.0t car (toureg hybrid, simos16, etc), but it isn't on the CTUB engine. The diagram is correct though if you me remove that servo pump pulley. Nothing else about it is different. If you have questions let me know 👍🏻
Shout out to @DDP352 for pointing this out!
Brother respect excellent information.
You are an absolute god send 🇩🇪
Nice vid keep it up 👍
Great video bro. Very informative.
Thanks man!
nice vid, very informative
Thank you!
I just watched your videos to do my crank pulley but I didn't seen to have as much space as you in service mode. Also the belt diagram you showed is different than mine. But other than some small differences and some skipped steps your video also works on C7 A7 🙌🏾
The belt diagram should be the same, but in glad the video worked for you!
The one you posted to screen shot has a "servo pump" above the a/c compressor and mine didn't have that but when you were showing your laptop with the program that had the correct diagram without the "servo pump"
Great catch! I didn't even notice that. I will make a pinned comment to address it.
Now I'm super curious. I wonder if the servo pump pulley is only on certain cars, or if that is a simos16 engine. Time to research haha.
I have no idea haha but the C7 A7 seems allot easier to work on. For instance I only have 1 10mm bolt holding the bumper on the side(with the 1 torx screw) and there was a small torx that was behind your bumper bracket that held the headlight in place mine did not have that. Also I see you don't have the metal lines that run down from the s/c how did you get rid of those?
Check out our video on divorcing the supercharger loop! 👍🏻
What’s the best setup for a crec engine pulley & tunes
So what happens if my harmonic balancer breaks how do I not mess up the timing or what you were saying about the marks
Hey Man, love the videos. Working on my car right now and have a few questions. Any way i could talk to you about somethings?
How many foot pounds torque are the pulley bolts?
Can you do a video on painting c7 a6 calipers? That or removing the calipers w/o painting
Already have two videos showing how to remove the calipers from the rotors. I do plan on doing a caliper paint diy this summer.
Awesome ! I have the 2018 A7, stock. The linear power band sold me. What stage pulley kit is this? Never explored doing performance enhancements on my car, a little intimidating to be honest. Can APR get this same Upgrade? Thanks for a very knowledgeable vid.
This would be for stage 2 dual pulley & works for any company than has that tune
What would you say is the best order of operation if I'll be doing the crank pulley & upgraded HX at the same time or does it not really matter? I was thinking bumper off, service position, pulley, then back into normal position & then HX. Great vid & thanks!
I'd probably do the crank pulley first & then the HX as well.
Love and enjoy the continuous info on our awesome C7s, Is there a dependable link to the emanual online ?
I clicked a few times but keep getting a
‘bad merchant’ prompt
Thanks in advance 😊

@@AudiC7Owners Beautiful!!!
Thanks 🙏 🙌🙌
Nice build bro!!! Are you by chance on stock cats?
Nope. I'm on gutted cats
I should of filmed everything I've done to my S6. I've rebuilt the entire suspension poly bushings and O34 everything. I've done just about every mod to the engine. No meth yet but that's coming. I'm getting it ready for paint now and finishing the stereo. I've filmed some things. So I'm thinking I'll do a finish video when it's done
Love this video! Quick question though, has your Cats gone bad while driving DP? Or have you already swapped the cats for down pipes or test pipes.
I have gutted oem cats
Thanks for the video. How does this compare to the APR dual pulley?
With the apr pulley, it was only large enough to be on a Single Pulley ratio tune.
The Velocity AP pulley allows me to run a Dual Pulley tune. There are some other differences, but I'm going to make a video covering all the info you need to know about different pullies & ratios.
@@AudiC7Owners I thought APR has a dual pulley setup and tune.
They do, but with theirs you have to have their crank pulley & aftermarket supercharger pulley to achieve the dual pulley ratio.
With this 205mm crank pulley you don't need to change your supercharger pulley.
Helpful… I’m going to replace the crankshaft pulley but I’m having trouble loosening the radiator and fan… what bolts and where do i do this because that’s the only thing really stopping me?
Why are you loosening the radiator & fan?
if deal falls thru on that APR 187 , I will buy it
It's already gone
@@AudiC7Owners :)
Thanks for all these informative videos!
I have no experinece working on cars but I would like to replace my own Harmonic Balancer and Tensioner Pulley.
Would it be too difficult for a novice?
From your video it seems relatively straightforward. I was quoted $800 in labor to fix both parts. I am trying to gauge whether I can do it myself and save the money or whether its worth paying that much to have it done.
If you recommend that I could do it, what exact tools would I need?
Hope youre able to give me an answer, it would be really helpful! Thanks!
This is not the job I'd start out with if you have zero experience working on cars. 800$ in labor isn't bad for this job at a shop
@@AudiC7Owners hey man, thanks for the quick reply. I appreciate the advice!
How can I check if my radiator cooling fans comes ON or not. Except once I never saw or heard them running when I come from driving and park my car on the driveway. So far no over heating but want to make sure.
Turn on your AC. They should come on
Say you forget to check the position of the offset bolt hole..... would you still be able to thread every bolt in without much resistance? Or do you think you'd notice once you go to tighten them? I did this job a little while ago and can't remember if I checked correctly so now I'm a bit nervous.
If you didn't get it signed correctly you wouldn't have been able to get every bolt in I'm pretty sure.
Can i just go stage 2 until my lower crank breaks? I don't want to install this 207mm lower crank pulley if its going to make my car run rough..can you confirm? OR.. should i go more expensive fluid damper pulley? I'm currently 2012 a7 apr stage 1
Why would the 207 make your car run rough?
What do you think about replacing seal while crank pulley is off?
The crankshaft seal? I'd only mess with it if yours is leaking
Crank pulley failure why
My friends crankshaft pulley is actually shifting back and forth. I’m not sure it’s supposed to move like that?
It definitely isn't. Sounds like it's about to fail
thinking of buying a 2012-2014 audi a6 with the 3.0tdi, is it really worth the extra money to buy the 245hk instead of the 204hk? Is it so much difference in acceleration that its worth it, or is it just dumb in the long run because of the extra fuel consumption? I need help!
That's a personal choice. You can modify the 3.0t to get into the 500hp range if that's your thing. If you aren't concerned with that & fee more concerned with gas mileage then get the tdi
@@AudiC7Owners thanks for the answer, thing is that its hard to find a petrol c7 in sweden, most of them seem to be diesels, you can find but its a 3k and up difference in price.. But thank you!
Are those Shady Ray sunglasses?🙂
Lol no.
Hey please help was wondering if I would need to grind with angle grinder to install the 187mm pulley or am I okay with that pulley
Yes. You will need to grind it down.
@@AudiC7Owners okay thank you. also one more question if possible. Do you think I would need to use an angle grinder to do it or do you think I could use just a hand saw to saw the few millimeters off. I might have to put it in service position to get a grinder in there ,but if I can use something else I can get in there.. Any reccomendations?
A hand saw will be a lot harder to do
Great tutorial!
I just recently purchased a new 180 mm aftermarket crank pulley and to my surprise my local mechanic refuses to install the aftermarket pulley because he said they are prone to engine vibration and even braking apart????😟😟
Please share feedback.
The oem crank pulley breaks down and causes more damage than the one piece aftermarket pullies ever have.
My only question is why are you going with a 180mm pulley?
@@AudiC7Owners For stage 2. This is the correct way right?
Pardon for my limited knowledge.
What size is your supercharger pulley?
180mm is just very small
@@AudiC7Owners 180mm. It's from CTS. I thought this was the correct upgrade size for stage 2.
OEM size is at least 20 mm smaller, so I thought 180 would work fine and give a bump in performance.
If you are also running the cts supercharger pulley (57.3mm) then your key ratio is 3.14. You can run dual pulley with that, but if you want with something larger you'd get a good amount of performance compared to the 180mm. Might try a 190mm pulley for the golden 3.3 ratio. Just make sure you have an upgraded heat exchanger.
I working on my Audi A7 2013. And my crank pulley keep eating my belt. But I noticed my crank pulley the grove part move back and forth is that normal.
No it is not. You have a broken crank pulley. You need to change it
No its not normal
My radiator is too close to the pulley and idk how to remove the radiator :(
Put the car into service position
Hello Cameron, I followed your instructions and was able to successfully install my 207mm JHM pulley and belt and my b8.5 S5 runs like a monster now. The only issue I'm having is that I'm getting a squealing noise now after installing the 7PK1360 belt. Is there anything I can do to remove the squealing?
Did you spill anything on it? Is the sound still happening and coming from the belt?
@@AudiC7Owners I spilled coolant on some of the idlers and the lower belt as well. You think some of the coolant that spilled is causing it? It's 3 days now and the squealing is still there. I hear it from the coolant pump pulley
Also, my water pump pulley wobbles at idle and I'm not sure if that type of play is normal or not
It definitely should not be wobbling. Has the water pump pulley been messed with recently?
@@AudiC7Owners not at all, only belts handles and the crank pulley. Would you recommend changing the water pump pulley? Or is the wobble due to the new install?
Do you need any software update to used it?
Yes
hi
intake and ethanol is required in dual pulley config?
No it is not
@@AudiC7Owners thx! ^^
@@AudiC7Owners and the intake either? 🤔
Nope. Stock intake is just fine
With stage 2 we can install big crank pulley??
Yes.
I can install on stage 1 ??
No
Did anyone else have an issue with the airbag light coming on after the repair?
Nope
With the 205 mm pulley is that stage 2 single pulley
No. It is a dual pulley ratio
I'm starting to feeling a little rumble to my a7 trans when it's going in the low gears like when I'm stopping from about 20mph to stopping. Any advice.
Could be anything from bad engine mounts/control arms to a warped rotor, or even a bent/unbalanced wheel
What about the serp belt? Just completely skipped that part lol I’ve taken my supercharger belt off 5 times never even had question on it. I cannot find A SINGLE VIDEO on the serp belt for these cars? My car has been down 2 days cause I cannot get the serp belt on. Feel so stupid what the hell am I missing why is there zero vids on ittt
I left my serp belt on while doing this, but I posted the diagram in the video showing how to route it. You need it on before you install & tighten any upgraded crank pulley
A shop tried to charge me 2,800 to replace my crank pulley 🤦♂️
Book time that is probably about right. Maybe a little high depending on their hourly rate.
Do you need any software update to used it?
Yes
