Audi 016 transaxle

New to this site. Great stuff!!!
I've searched the archives but not found.
Can anyone help me locate a drawing of this transaxle showing the important dimensions? I need the length, width, mounting locations, location of the half shafts relative to the length and the input shaft.
Are the axles and hub carriers worth considering in a relatively low hp application?
Thank you very much,

Al Keller

Good luck. I've never seen a dimensioned drawing of an Audi transaxle, only exploded-view drawings on the EKTA parts database.

These trannies are cheap in US scrapyards...$ 100-200...
even cheaper if you get one from a U-pull it place.
Much easier to mock up with real pieces...

I know of no one using Audi axles/carriers...typically
those are supplied by the chassis maker.
Good luck.

Al, Where are you located and what are you building. I have used these transaxles in several applications and I can give you some information about what axles and hub carriers can be used with them.

 

[Ron Earp]

Search the Engines forum too. Both Transaxles and Engines used to be combined, but then I split it because Transaxles got too many posts. However, I've still not moved all the transaxle posts out of the Engines forum. It is boring and tedious work. Right now there are more transxles posts in the Engines forum than there are in the Transaxle forum.

I am going to try attaching a PDF of the dimensions I got off my 1985 016. Disregard the 2.83 dimension from the face of the bellhousing to the throw-out bearing because I'm not sure what position that bearing is in. I'm assuming whoever took the tranny out had cut the slave line BEFORE pulling the tranny away from the engine in which case the bearing is most likely in an clutch "engaged" position (pedal NOT pressed). You probably won't need this anyway unless you are making you're own adapter / flywheel.

Also - looking at the side view, the shifter rod is the circle that is up and to the left of the triangular group of mounting bosses.

Just so you know - I took these measurements by first scribing a line up the middle of a piece of plexi-glass perpendicular to what is now the "bottom" edge of the plexi. I then machined a very close fitting hole for the input shaft on that line up a ways from the bottom edge and slipped the plexi over the input shaft. With a sharp pencil, I drew two perpendicular lines on a piece of 1-1/2" birch ply. One represents the bellhousing face from a top view (to line the plexi up with), and the other the centerline of whole tranny. I then propped the tranny up off of the wood (because I machined the hole in plexi high enough to do this) and squared the plexi off the wood surface. Then I rotated the whole tranny until the output drive flanges were both as absolutely perpendicular to the wood as I could get. Of course the plexi is now clamped to the bellhousing. Now everything is square and I have all of my datums to start measuring. I did this with a plumb bob and calipers wherever possible, steel rule or god-for-bid a tape measure if I really had no choice. The results I feel are well more then adequate for designing a car. I also took a shot at placing the holes in the bellhousing but that proved to be a lot more difficult because as I found out many of the holes are severely tapered for the molding process. Plus, there is always a little bit of lateral play in the end of the input shaft, and I'm sure how much it moved "up" relative to the tranny because of the weight of the tranny while supported in this measuring jig.

Good luck.

Oops - forgot mounting dimensions. Just added them. I don't remember what the threads are for the CV's. Also haven't figured out what gear it's in right now (as you can see I haven't built my car yet), so I couldn't give more detailed info on the shifter rod - but that's probably unnecessary anyway.

Chris, thank you very much for bringing the tech in the two above posts. Nice work!

Chris,
Very well done. This will help alot of guys out.

Thanks Chris,
This helps me out aswell. Fine job.

 

Chris,
Thanks very much - that really helps a lot of us out.

Wow - glad so many could use it. Just remember not to take all those dimensions as gospel. I didn't go to 3 place decimal because I wasn't able to measure that precisely, but I could do better then 1 place. So 2 it was. It should be plenty to get a really good head start on a design.

Geez - can't wait 'til I move and get some room to start my own damn project.

 

Hello.

From what year and modell do I find the 016 Audi transaxel?

016 = 5-speed ?!?

Why is the AAZ the best trans? Is it?

For my project, I would need to flip the ring gear in the 016 transaxle - I know, that's weird! At any rate, can that be done and would the gears "live" in that configuration?

As always, thank you.

The 016 boxes have the selector shaft on the left hand side, all other boxes have the shaft in line out of the back of the box.

Note that Audi 200 were later versions of this car and the 9000 range were again the same but the American version of the car.

Guys, I came across this tonight in my travels, looks like it will be very handy it's the complete Audi 016 workshop manual with pics, hope it helps.

The gears in the 016 cannot be flipped. It is a hypoid gear set which means that the pinion is not on the centerline of the ring gear. You can only flip spiral bevel gear sets (like on Porsche G31, 901, 915, 930, G50) because the pinion is on the same centerline as the ring gear.

The question was, can the Audi drive train be used on lower HP cars? I ran this equation thru my little brain and it said.. half the weight and running in a straight line must work when they are designed to take all that steering load plus the car weight. I made new housing`s and welded the new upright structure to that. Other ( I never thought of it) used the origional centre cut out and the re fabricated. I have attached a picture of what the rear looks like. The AUDI axels I had were different lengths so I just got a matched pair that worked out as my correct track width.

Great work, I know how difficult it is to measure something like that.

Anyways would you know where one could get the bellhousing bolt pattern dimensions for the 016 box? Im stuck because I cant find a engineering workshop that can cut me an adapter plate without schematics?
