CBL Gearbox - Part Numbers?

[sheppardnias]

Could anyony one please let me know what the correct part numbers for the following are:-

1) Seal on the flange of the propshaft drive at the back of the box.

2) The large O ring that the propshaft flange bearing housing has on the mating fce to the Torsen diff.

Searched Vagcat but I can't find the parts. Local stealers were not exactly sure either and in honesty are not that interested in helping unless they get to carry out the work.

Cheers

Try Vagparts?

I just did these on both my urS. I replaced the bearing on the flange seal also, but I don't think it is necessary. Here are your numbers.

01E 409 400 flange seal
N 90545201 Large o-ring seal

If you don't have some Audi gear oil you might want to grab some as you'll loose a liitle during seal replacement.

Thanks for the info. I'll get the order placed (probably through VagParts) and get the seal changed...

The box might not loose much oil but it doesn't have smell as the oil drips on the right hand catalyst...

Mine was doing this when I first acquired it. We thought it was the seal on the bearing where the propshaft meets the gearbox, but it turned out to be the entire bearing unit was loose! Luckily this was only a £50 2nd hand part.

And you're right, it does flippin' stink!

I think that I read your post on this before I bought the car. I know when I smelt it, I immediately decided it was leaking from the back of the box and that I'd no doubt have a nightmare sorting it and that the bearing would be in need of attention.

In the end it cost £10 for the seal from Audi, £15 for gearbox oil and took far too many hours lieing on a wet drive with my beer belly wedged under the car whilst I swapped the seal.

In reality it was an easy job to do but I just couldn't get enough height on the car to work easily. My bearing felt as good as new, fortunately. I also think that the seal had leaked for years. The shield that lives on the end of the box had a very thick layer of grimmy crud which was baked on. When i cleaned it, it looked like it was new again.

Yet another niggle(?) on a car sold as niggle free... Makes me wonder what some people consider to be niggles really. When is a niggle not a niggle?

Instead of pulling the seal on the car I pulled the bearing housing, the last 12cm approx, off the gearbox and replaced the parts on my bench and then bolted it back to the end of the gearbox. The bearing housing is held on by a few Torx bolts so it's easy to remove. Don't forget to replace the large O-ring ion the bearing housing before re-installation.

I replaced the seal and bearing on my wife's S6 Avant this weekend. The bearing was in fine shape and the seal was the only problem.....just like you experienced. My S4 was the same, bearing fine and seal leaking. Both cars had the cruddy shield from gear oil and dirt melding together. I've got a few pics I should post.

I pulled the bearing housing too. You have to from what I saw because the shaft has a circlip on it on the far side of the bearing. If it wasn't for my nose touching the floor of the car and my gut trying to lift the car off it's stands it would have been an easy(ish) job. Once I had the housing in my hand it took 10 mins max to swap the seal. The hours were wasted in A) getting the car up safely. B) getting the 6 bolts undone between the cats and the down pipes.


What I did do was the following:-

Undid the 6(?) bolts that hold the housing on the end of the shaft. Waited for it to pop off under the force of the spring. Nothing happened , so I placed my little bucket under the back of the box to catch oil. Tapped the housing with my soft faced hammer and watched in horror as the housing lept at my face in an arc.... Fortunately the housing is true Audi and weighs a ton ,it therefore landed in my bucket. The bucket had a dribble (1 litre I guess) of engine oil from a diesel in it...


Thinking I was lucky to have a face, I rummaged in the oil for the housing, rings and spring that had launched at me. Feeling smug at my ability to take things apart with my trusty hammer, I went to my shed and swapped the seal.

When I ambled back to the car I was met by the most horrific sight I ever saw... The bucket had a 2" hole punched in the side from my stupidity and the engine oil and gearbox oil mix had run all over the drive. The drive is a cobble effect so the oil had gone far and made a lovely mess with a black sea between 80% of the cobbles on the drive.

Spent 30 minutes mopping oil before I could even get back under the car. What made it worse was looking up to find 'she who must be obeyed' stood 5 feet away staring at my mess.

Not my finest moment and I ended up with a driveway that you could skate on.... Took some time to shift it all even with a power washer and every detergent I could think off to shift oil..

[andrewd]

Sounds like you had about as much luck with that job as I usually have whenever I get a spanner in my hand!

Glad you got it sorted .. and the drive cleaned up!

Count yourself lucky all of you... I live on the south circular A205 and I get funny looks from my neighbours even if I only change the bulbs in my headlights... I'd love to be able to do any work on my car myself......

Beautifully written.

We all btdt with oil 'escaping' and making a mess.

Thanks for sharing.
