Thanks for the drawing, seems pretty simple and I am going to replace the the part just need a part number. I also have a Cayenne turbo S and do all my own work on these cars. I am a car builder and have built many over the years. I am going to call my local porsche parts guy and see what he can do. Hell if I have to fix the existing screw it can be done, and if I fix it, I'll make it where it doesn't fall apart under very slight torque.

Thanks again for the info.

 

PM a mod, it’s important this is updated as many DIYers will just read the first post and not the years later follow up discussion

 

Yes the fill hole for PDK fluid is hiding behind the coolant hoses and is easy to get to. I'll PM a Mod.

 

Update: the first original photo was removed since it incorrectly showed the wrong plug. Everything was left as is.

 

good call on removing that picture. I can’t tell you how much time/anxiety it caused when I pulled that bolt out.

 

@JackF can you also remove the pics in posts 34 and 39? Those are also the same picture showing the wrong fill location. Only picture 36 has the correct fill plug pointed out (so this picture needs to stay). Thanks!!

 

no reason for the attitude, I have clearly stated below the picture that it’s not a correct bolt…

 

I'm posting these incase someone is not seeing the pdf. It has clear photos of which bolt is which and part numbers for the liquids. I guess I can update the plug part numbers too.

I have a 991.2 GT3. Ordered an OEM pan/filter and new aluminum fasteners. Service Manual states the following:
"2. Aluminum screws are secured using the yield-point-controlled method
3. Use special torque wrench 9768 for this
4. To ensure the screws are tightened uniformly, the specified tightening setting "light. medium or hard" must be used"
An initial tightening torque of 2.4 NM is called out followed by Tighten M6 screws at "medium" setting.

in all my years i have never heard of a light, medium or hard" setting on a torque wrench. If you are torquing to yield, usually there is a specified torque listed, in this case 2.4 NM followed by an angular component (90 degrees as an example) Nothing besides the initial setting of 2.4 NM is called out other than tighten screws at medium setting whatever that is. Torque wrench part number is 000 721 976 80 and lists for around 5K. Not sure what so special about it. I have a digital snap on 1/4 drive that will torque to 2.4 NM no problem. It's the medium setting that baffles me. Anyone have any additional info on torque values or method for these fasteners? Thanks in Advance.

 

Yeah, I read the same. I didn't use any special torque wrench (just a regular inch torque wrench) and so far so good on mine. I just followed the screw order to remove and install. If I recall correctly, I went around twice (if not three times) to make sure the bolts were all correctly torqued. The bolts are aluminum and feel very easy to strip.

 

Copy, Thanks. 2.4 NM is not a lot. Works out to be close to 2 ft lbs. I thought that was a little low but as you said they are aluminum

 

Yeah, that's another reason why converted to inches and used my inch wrench. My foot lb torque wrench is overkill and didn't want to take the chance of stripping one of those. I remember reading somewhere that you're not supposed to use a torque wrench at it's lowest or highest limit.

 

Reviving this old thread, I'm about to do the PDK service and this also confused me, as did the term initial torque with no follow-up on subsequent torque spec?? I've also gone through the service manual and looked at the torque specs for the drain and fill plugs on the PDK and noticed all have a torque spec and a second column showing "tolerance 1" which was like +/- 2 NM and another "tolerance 3" which was empty, but for the pan bolts there was nothing on tolerances, just the 2 ft lbs. Did you ever figure this out? If you stuck with 2 ft lbs, have you checked to ensure it's holding up and no leaking? Thanks in advance!

 

Does anyone have any experience with clutch fluid other than the FFL3, such as Motul DCTF?

im about to do this on my 991.1 and purchased the Beck/Arnley PDK transmission pan, and Liqui moly fluids for the clutch oil and gear oil. I also got an extra gear oil for the rear differential. Links are all below:

https://www.summitracing.com/parts/b...-0408#overview - Pan at the time of purchase was $121

https://www.ecstuning.com/b-liqui_mo...BoC0C0QAvD_BwE - Liqui Moly 8100 5L Dual Clutch Oil purchase price $73.50

https://www.fcpeuro.com/products/gea...ly-99991754600 - Liqui Moly Gear/Differential Fluid purchase price was $19 x 4 = $76

These are the cheapest prices i found for each of these products.

BTW, this is not very helpful, but I recently put Motul DCTF in my cayenne's transfer case.
