remplacement du différentiel du pont R180A par un Quaife

[sparkybg]

Yes, I make them to be able to use original bushes. This was one of the things I did not like in Calmini arms, and I changed it. You can use both original rubber bushes, or for example SuperPro polyurethane ones.

As for the R200A - I will keep you in touch of course, but I suspect the mounting will be a slow process.

Ok, that is a good news. I like the original bushes. The calimini ones are too rigid. What about the superpro material? Are this bushes between calimini and original bushes ? Are they a little softer ?

Yes for the mounting of the R200A this will take time. I had more then 6 months work until the Quaife was installed. but I never regret doing this. But take in account that the front axle will have more mecanical stress with this differential. The problem will be on the well joint, or on the hub screws. On my models this screws are often come unscrewed or sectionned I have replaced one of them by a larger diameter. Since this, I have no sectionned screws, but they continue to come unscrewed. But this is no more a big problem. The T2 will change of performances. He will become more tractive in opposit to an propulsive performance of the standard Terrano. That is very good for crossing.

I had similar problems with bolts on my AVM hubs without changing anything else. For the moment I use some sort of chinese hubs, and there is no problem with their bolts so far. Anyway, there is several kinds of thread lock adhesives on the market today. Some of them bonds the bolts in the thread very hard. I may consider trying some of them.

Anyway, this is a common problem on T2, and not only on T2 but other machines too. Several friends here had just the same problems with their vehicles.

Here in France, on this forum, I seam to bee the only one how has these problems with hub screws.

Ok, It s good to see that I m not the only one in the world how has this problem.

For the superpro bushes - they are way softer than Calmini ones, but they are harder than the originals. I still cannot tell what is best - to use original rubber ones, or to use Superpro polyurethane ones.

Just made some basic inspection today on R200A and H233B differentials I bought. As far as I can see, these are in exeptional condition, just like new. There are not any signs of wear and usage. I am very happy with this. Front CV joints are in "like new"condition also.

Tomorrow I will be able to tell if T2 outer CV joints will fit the T1 V6 shafts. If so, it appears it will be an easy task to put an R200A on T2.

for a "normal" usage i'd say originals are OK.....200 000 and now mine are shot after a winter of UK roads.......

Poly might give you better handling but since harder will transfer stress to other components............and once deformed they never really come back to original shape as rubber does (but then again they don't crack or dry out)

Vincent sch, here I have a little question.

How did you manage to put the short flange lock nut inside the Quaife differential? This is the little part where the bolt at the center of the flange bolts in?

Did you had to make a modifications on the nut or on the differential in order to put the nut inside?

Thanks.

[vincent sch]

Hi,

Yes, I had to use the original bolt to mount the short flange on the Quaife. Quaife bevor I bought the new differential, verified that the Quaife mounting bolt diameter and the good bolt angle was the same as the bolt on the original differential from Nissan. This was OK for me.
The Quaife is installed and mounted the same way as the original differential.

You can find all the dimension of the Quaife on there web site. You find a PDF to download with all technical informations: Number of teath of the flanges to fit in the Quaife.

If you don't find the informations, I could search this for you.

For information, it's inpossible to make modifications on the Quaife differential. The steal used for the Quaife is very very hard and you need special tools. (Diamond tools are needed. I had to got the holes for the mounting of the crown biger. And no normal tool could be used. )

Thanks again. I will keep you in touch with my project.

I have another dilemma. There's original Quaife and also OBX brand of helical differentials available for R200. And the OBX costs three times less. Now I wander which one to buy. Any thoughts?

[vincent sch]

I don't know what OBX is. I never heard of it. Can you send us a web site link ?

The Quaife hase a life garanty. I never had problems with this piece. I had explosed axle joints, and other pieces of the transmission but the Quaife resists very well.

The Quaife is like a Torsen. It's not a standard limited slip differential, it will distribute the traction force on the well witch has the bigest grip.
