Possible gearbox leak fix..... seems to work!

[SmokeyTheBandit]

I was a bit fed up with the stupid leak, even the TND fix wasn't able to get it even reduced a little.
So as in my case it couldn't get much worse i decided to see if i could do anything to improve the design.
The two parts that you put arround the shaft are not rubber but hard plastic so it doesn't avually close all that well.
A small ammount of liquid gasket can overcome just that fraction of a mm where the oil is comming through.
The TND kit itself is needed to get this done!

What do you need :
* TND kit
* High temp liquid gasket
* Gearbox oil

What do you do :

Obviously you need to get the oil out.
Follow the instructions of the TND kit.
When you come down to clamping the plastic bits arround the two o rings.
This is where we begin with the modification.
Leave the shaft as it is do not clean it (needs to be a bit greasy!).

It should look like this at that point :

Put some liquid gasket arround the outher side and the inside on both parts (as marked)
Sorry my paint skillz suck :tongueout:

Then put these arround the o rings and jam them in!
Secure it with the metal clip and your done!
I waited 2 days before i filled the gearbox up, give it enough time to dry.

I have driven arround 50 miles now so far and no oil has come out, its not even sweating!
At first its very hard to get it in gear, but after you driven a bit it gets allot better very fast.
I don't know how it will work on the long run but it was worth a go :up:

I will give this a try when i done mine soon before next weekend.How was the kit to fit?

 

[Gus]

Good Effort Martijn. :up:. Can you update in a week or two and let us know how if you still have no leaks.

 

[SmokeyTheBandit]

The kit is very easy to fit, but takes a bit of time due to the oil that has to be removed.
I have to drive 500km's this saturday to get the sunflower mapped by Henk so im able to give an update this weekend :wink:

 

[MrBlonde]

What liquid gasket did you use mate?

Also have you a little guide on how to fit the kit if possible please to?

 

[SmokeyTheBandit]

I used a common brand thats available here in the netherlands.
But its normal high temp (up to 300C) liquid gasket, nothing fancy.
Should be part of your standard car guy garage inventory basically :tonguewink:

Regarding the instructions found this : http://www.cliors-concept.com/kit-joint-tnd-pour-bv-jb-jc-t41419.html

 

[MrBlonde]

Ahh its in french mate i think??

:up:

Sorry,TND kit has gone over my head.
Link please?

 

[SmokeyTheBandit]

You can buy it here

Mapco produces it as well it seems, looks exactly the same though :up:

Only way to fix it properly is to replace the seal and the bushes that the selector shaft actually pivots in.

 

[SmokeyTheBandit]

I agree @NorthloopCup but this is possibly a very cost effective way to at least reduce it considerably or even stop it (time will tell).

Unfortunately I think once the oil is warmed up fully, or even overheated, the sealant won't be doing much of a job. Those TND kits are just way to hit and miss with the tension of the o rings as well for my liking.

 

[SmokeyTheBandit]

I agree, without the sealant the kit was pretty much useless. Didn't improve at all.
Thats the reason i went for it, as it couldn't get much worse anyway.
We could only go up from there :up:

Ill post an update after it has been dyno'd and driven for 500km's this saturday :up:

do you have a link to the parts required?

 

[NorthloopCup]

do you have a link to the parts required?

R82 01 048 885 is the part number for the seal and bushes, and they're £15:33 + vat for the kit mate.

how hard are they to change with the box out, im about to remove mine to change the clutch, it weeps just a little but would like to fix it if its easy to do?

thanks again

You need to open the box up mate to replace them, so if you've had experience of opening a box up, it's around 1hrs work.

an hour until you find everything else that's wrong while you're in there!!

 

[NorthloopCup]

In that case 1.5hrs. Lol! It only takes me 10 minutes to strip them anyway.

has to be said they are a pretty easy one to strip down although nowhere near as easy as old ford three rail box...am showing my age a bit there:laughing:

Hay

I have read your presentation about the leak discovered on your clio (three years ago).
Sorry for my poor english because I am french.
I have the same problem as you on a Renault Megane dti.
Could you tell me if your solution has worked a long time.

Thank

Hi,
i think most of you don't have your clio 2 anymore. I still own clio 2 1.2 16v with jb1 gearbox. I applied this method with high temperature silicone seal and actually it works. I drov 100km and there is not even a drop of oil coming from Selector end. "BUT" it is very very hard and difficult to shift it was a nightmare, after applying grease to the Selector end it is now shift very smooth. Thanks for help

I wouldn’t worry, probably infinitely better than me trying whatever language you speak as your native tongue 👍

I fitted one of these kits. Terrible! Leaked worse after fitting.
