Hi

Thank you for this informations.

Perhaps I didn't undertand all. :hein: But I think you should find a R200A model with flanges with 6 holes in 2x3 groups of holes. Find the R200A without taking importance on the inner ratio. Ring gear and drive pinion are not important at this time. If you have found the good R200A with the good flanges. You should conserv the inner differential and separate the ring gear and drive pinion. The ring gear is fixed on the differential with bolts. And I think all R200A have the same bolts. The second operation would be to find a R200A with the good ratio, the same as your rear axle, independent on the type of flanges. To separate the drive pinion and ring gear and mount this to pieces on the first model. I am sure at 90% that the ring gear of a R200A model with no good flanges will fit on a R200A with the good flanges.No ??? :)

This is exactly the problem. I cannot find a terrano with proper flanges. These are mounted on pre 1990 pathfinders and terrano 1 V6. There isn't any of these present on any scrapyard here. Yesterday I was able to get the VIN numbers for all four terrano1/pathfinder V6 that I found here, and all of them were with the 5 bolt flanges.

I don't care for the ratio. In fact I was thinking of changing to a 4.625 ratio axles anyway. The cheapest one i found is 1994 with automatic transmision, and these are with 4.625 instead of 4.325. So I will be able to mount R200A with Quaife in it, and change the ratio to 4.625 at the same time. Of course, I will have to change the rear axle ratio too, but this is not a problem because the rear axle on the donor terrano is also present, and on top of all this, I will be able to negotiate for a better price for both axles. I am pretty positive that I will be able to get the entire front differential along with the CV joints and hlfaxles + the rear 3-rd member for about 300EUR. I am able to change the gears myself, so there will not be more expenses, except for the Quaife carrier itself.

Hi

OK, I have understand your problem. You said it, the solution would be to take the R200A with the front half axles. Are the heads of the half axels compatible with the wheel side ? Is the number of grooves the same as on wheel side ? If not, could it be possible to replace the joint assembly on wheel side and find a joint witch fits on wheel side and on drive shaft ?

300 euros for all this peaces is a very good price. Here in France you could not find a front axel under 600 euros :ouin:

Salut à tous,


Voilà je relance le post. ;)

Est ce que quelqu'un pourrait me dire ou trouver la dimension du diamètre du différentiel au niveau de la fixation de la couronne d'origine R200 ? Je voudrai savoir si c'est la même dimension que sur le C200. Sur le C200 c'est 128mm .
Oubien est ce que vous savez ou je pourrai trouver un R200 vraiment pas cher pour décortiquer le différentiel et faire des recherches de montabilité d'un différentiel de R200 dans un C200.

The differential itself is absolutely the same. The crown and especially the pinion are different between R200A and C200. There are 2-3 types of R200 - "long nose", "short nose" and so on, but still they share a common differential, only dfferent crown and pinion.

Are you planning to put an R200A in front? Mine still waits for enough spare time to mount it up. What happened to your Quaife?

PS: I found a proper flages also.

Here's what I found out about the front end of T1 and T2:

To put R200A form T1 on T2, there are 3 options:
1. To get an R200A from older T1 (pre 1988 I think). These are with proper flanges for the T2 inner CV joints.
2. To get an R200A from newer 3.0 petrol T1 (after 1998), together with inner and outer CV joints, and half axles and whole front knuckles.
3. To get an R200A from newer 3.0 petrol T1 (after 1998), together with inner CV joints and half axles and get outer CV jounts for older 3.0 petrol T1 (pre 1998), or 2.7 diesel T1, or 2.4 petrol T1. These outer CV joinus will fit the T2 knuckles, and will fit the 3.0 petrol T1 half axles, which are with bigger diameter then T2 ones.

3.0 petrol T1 with manual gear box is with 4.375 differential gear ratio.
3.0 petrol with automatic geat box, 2.7 diesel and 2.4 petrol T1 are with 4.625 differential gear ratio.

If i can be of further help - let me know.

Hi Spartak, ;)

Thank you for helping. My front Quaife is OK and I will not have to change the front differential. I’m looking for changing the rear differential and I have seen that there is much more possibilities for replacing the differential of a R200 with other LSD.
The LSD of Nissan in the rear axle (C200) is too weak. I’m looking for something else to replace it. Could you give me the number of grooves in the R200 differential?
Is the lateral position of the crown on the same place as on the C200 ? Or if there is a difference, could I use a hold on the R200 differential to adjust the crown so it will be on the good place with the pinion.

Well, as far as I know, there are C200/R200 with 29, 30 and 31 grooves. Everything else is the same.

I suspect your rear C200 is with 31 grooves, which is a more or less "rare bird". Most of R200 differentials are with 29 grooves.

You may consider replacing the whole rear axle with H233B, which is far stronger than any R200/C200. You will only need the right crown and pinion to match your gear ratio (4.11 I think).

Hi Spartak

Yes I have 31 grooves on the C200 differential. Yes replacing the rear axle with a H233B would be a good solution but I have a 3,9 ratio and this ratio does not exist for the H233B :ouin: :confused: 39 teeth on the crown and 10 teeth on the pinion.

I should replace the too axle, the front and the rear axle with a ratio that is near the 3,9 ratio. But I dont want to remplace the front R180A axle with the Quaife that is perfect on the front. So I should find a ratio that would fit in the R180A.

The other solution is to find a other LSD that's fit in a R200 differential and to find the axle shaft with 29 grooves that fit in the "standard" R200 that fit in the rear C200 axle.

That's are good news to see that the C200 differential is exactly the same as the differential in the R200. So I will look for the different solutions existing for replacing the differential R200 and look exactly the number of grooves on the solutions. :hein:

Salut à tous

Quelques dimensions et photos pour compléter nos connaissances sur le R200A.
R2004.JPG
R2001.JPG
R2002.jpg
R2003.JPG
Les différences avec le R180A

La hauteur totale du corps R200A est plus haute d'environ 35mm par rapport au R180A. Si je veux utiliser ce pont, il faut que je pense à rehausser la caisse mais également le moteur de 35mm.

L'autre différence est la fixation des demis arbres. Ici c'est 5 vis alors que sur le R180A on a 3 groupes de 2 vis.

Le reste est très sensiblement identique. :)

si c est que le ratio qui t empette
tu as pas la posiblité de prendre la couronne et le pignon au bon ratio pour les monter sur le plus costaud: Hein:
