Thats alwesome, I never could picture where the plate went, but pictures are worth more than a thousand words.

So I just have to take the 5the gear assembly apart again and install that plate and it helps alot?

Thanks for the post

One of the typical failure modes of the AUDI 016/083 is that the rear pinion bearing pushes through the rear housing. This is a product of drag race starts. The plate pretty much eliminates this.

Took the the rear housing to a machine shop today and was very surprised when I was quoted a price of $160 to mill 1/4" off. Any suggestions?

I haven't torn into the back, but from all the pics of the plate swap. I would venture to say that a spacer the exact thickness of the plate can be made to go in between the shaft and the inner half of the angular contact bearing....No milling of the plate required. Can somebody confirm this?

It is my understanding from the pictures the aluminum end cover has to be milled 1/4" to offset the thickness of the reinforcement plate.

If you look at the pic the angular contact race looks like it can be spaced out 1/4 to 5/16 inch. If this is true, then the housing does not have to be milled. IMO the milling of the housing weakens it at the base...

This sounds to me like they don't want to do the job. The machinist at work told me that it would be a very easy job, maybe 1/2 hour. I was just curious because I am not using one of those transaxles.

As for what xschop stated, I don't know. I haven't looked at one of these for a couple of years.

If the base is not set up properly and perpendicular, then the milling plane will be off kilter and guide pins will enter at a slight angle and the 2nd outter half of the angular contact bearing will wear out prematurely. That set up time sounds overkill, but who knows. Check another machinist. But this is how I'm going to go about the task when I get ahold of a turbo tranny....

I have a question in concern to the schematic in the manual for this plate.

It shows a hole on the left side .3346 Dia x 7
one hole .4723 in dia
.5569 dia x 3

thats 11 holes but there are 13 holes all together other than the big cut outs for teh 5th gear set.

can someone help

I have not installed my plate yet but the two extra holes maybe for the dowels.

That's an interesting idea, xschop. However, from what i've seen from doing four 5th gear swaps...i don't think there is 1/4" of room there.

Also, one or two of the rods that the shift fork rides on use the back cover for support.

Hey Porch, looking inside the housing, does it look like a 1/4" to 1/2" THICK bridge can go across the top of the gear inside the housing and connect the reinforcement plate? I thought about the shift rods and wasn't sure if the rear alloy housing was an end guide. I would just copy the end extension that I would have to make to screw into the back of the Reverse Rod switch mechanism and do those the same way with loc-tite after drilling and tapping the rods.

Hmm, i'm a little confused about what you're asking about. Can you draw me a picture of what you're suggesting? Here's my pics if they help:

Looking at the pictures, i think i might be wrong about one of the shift rods going into the rear cover. However, i seem to recall there being something in the back of it...

Is the smaller helix gear the actual 5th or the 5th counter? Whatever it's called, I'm going to machine my plate to incorporate a bridge over that gear that will make the reinforcement plate where it will not flex under load, That's where the rear pinion shaft wants to push out under acceleration and the cast part breaks....I need to find a good turbo tranny

If my Bare Bones install kit sells, I'll get your tranny from you. Free shipping to OKC?

Post  cfgioja Tue Jul 27, 2010 12:11 pm

I have realized that after taking this schematic to the local shop to have a suggested price done for the plate. The schematic is missing alot of information.

It still is shy two hole measurements and all of the outside measurements and radi.

It has the full width and hieght of the outside but nothing else.

Can I either get someone to get me a good copy of schematics that I can have machined without paying double for them to figure out the angles.

Or

Can someone make a duplicate plate for me? I will see if I can get ahold of Greg too, he has one on his site.

Yeah, the ebay price is free shipping to anywhere in the lower 48. Oh, and there's someone in the FS section of the board who wants the 5th gear out of it in trade for an N/A gear + cash.

I need to know one the chematic, the holes that are cut to go around the fifth gear set has two deminsions. I am not sure if that is a step in the metal or an angle? Can someone assist please?

Where is this schematic found at? Is there some reason that thicker plate could not be used? Like maybe 3/8 plate? I could not see any issues that stood out at me? How many people have done this modification so far?
