BX 4x4 / 4WD transmission shafts reproduction?

Post by ssiegert »

Hi,
third try to post this.

since 2018 I am the owner of a BX GTI 4x4. I imported it from France ignoring all the warnings in various forums to stay away as the gear box and rear axles are too weak and spare parts almost not existent.

One big maintenance job later done by a specialist, replacing the 23 year old tyres and the Sphères, it rides smoothly and makes a lot of fun.

Recently I was able to buy all three gear boxes from classifieds and took the main and the transfer box apart. Quite worn in my opinion.

I am in serious contact with a company, that can reproduce the shafts from main gearbox into the distribution box on the 4x4. Want one or do you know somebody, whose BX is stranded because of these? The more people join in, the cheaper these parts will become. These are the culprits. Too weak in construction. I have sent the original parts over to the shop yesterday, so that they can evaluate potential improvements and give an estimation of the cost. I am asking people in Germany, UK and France and wonder if 10 sets are needed. This is a private initiative, so I can only start this if enough people at least indicate interest.
Contact me please.
Thanks and regards
Sebastian

Everything depends on the price. For allready some time ago there was a company in Finland that repaired the axles by welding new stubs, I don't know if it still exists. The cost was around 300 Euros at that time if I recall it right, for a pair that is. Of course now we have all 3D scanning, CNC and even printing so I'm really interested in the price for whole new axles.

Hi Kaapelimies,
You are on my list. :-) Thanks for raising this.
There is a company in Austria near Salzburg, that offers the same according to a colleague from the Citroen Veteran Club here in Munich. they charge about 500 EUR for welding, cutting and hardening, but I believe a completely new and improved part might be better. Even at a higher price.
Thanks again for indicating interest.

The search continues: I got a rejection by the company that evaluated the transmission shafts. They don´t have the machinery to reproduce the shafts with the internal sprockets. :-(
So I will have to continue to search for companies or solutions.

Maybe a company which does titanium 3D printing?

As mad as it sounds, it's cheaper than you would expect and the resolution is incredible. Any shape is possible then

A 4x4 owner on here many years back now found a solution when his splines failed. He had a local engineering company machine out some grooves and fitted what he call dogs into the grooves to give a fix and a much stronger coupling. I don't know any more than what I have written but there must have been some sort of retainer fitted too to keep them in place.
Something to think about perhaps ?
The Joy of BX with just one Citroën to my name now. Will I sing Bye Bye to my GTI or will it be Till death us do part.

Hi Jaba,

I will discuss this with the machine shop.
All ideas are welcome.

HI,
just a quick update: Last week I sent the shafts to yet another company to evaluate whether they can reproduce them. I expect a reply this or ext week. So the project is not finished yet.

Hi Folks,
yesterday I received an offering for the reproduction of the transmission shafts.
One set: EUR 4.000.-; 10 sets at EUR 1.750 each; 20 sets at EUR 1.450 each and then there is VAT coming on top.
Two immediate questions:
1. Would the price at 20 units be interesting at all?
2. Could we find 20 people interested? In Europe?
What do you think?
Thanks and regards

I'm totally out of interest at that pricing, sorry..

HI Kaapelimies,
No apology needed. This is what I wanted to know and frankly, expected. I have no intention to put a set on the shelf either at this price level.
Thanks for your quick reply.
