That's great news from Skandix (assuming it's any good!), much cheaper than comparable alternatives.

Has anyone ever tried fitting a coaxial slave cylinder (e.g., from a 900) instead of the standard slave, fork and release bearing?

Have not tried, but I have that kind of modification in my mind for next development step for clutch. I think pressure bearing lever could be modified to install that kind of slave cylinder to it.

I think there might be not enough space for 900 slave cylinder, which is in your picture, but probably there are smaller cylinders available.

Hi All,

Revisiting this with the intention of getting the rebuilt engine fitted to the 96 this winter.

The main stumbling block I have is a lack of knowledge around which release bearing to use if I use the TYP M 200 pressure plate I have.

Looking at alternatives I figure it may be cost effective to buy the Scandix kit at 289 Euros.

Has anyone bought one of these kits? In the image on their website the diaphragm is shown without a centre ring (like my TYP M 200) and I wonder if the release bearing supplied with this kit may work with my clutch...? However I can't find the release bearing listed separately on the Scandix website...

I also wonder what pressure it is rated to as I worry that I may get slipping issues like Antiik did.

Thoughts appreciated before I commit to ordering the kit.

Thanks

I've always looked on these internal slaves as an unnecessary backward step. Failure means a total strip down, gearbox off. Who needs that when you can change the standard outside one very quickly and easily.

Derek,
I agree, seems a massive faff to separate the engine and box to change a slave cylinder but I suspect they last as long as a clutch.
Just had a full clutch and dual mass flywheel in one of our work vans (Transit with less than a 100k) and slave was fine but replaced as a matter of course.

I’m now erring towards having a top hat bush maxes for the TYP 200 pressure plate.

Do with think stainless steel is appropriate, I think as the release bearing does the spinning the bush shouldn’t wear or do I need a harder steel.

Also thinking of drawing and having cut a trigger wheel that will act as a spacer like the one in the link on page 1. I would just buy one but out of stock.

Cheers

The Borg & Beck slave in my '88 900 gave up the ghost after just 12k miles the other day, the original one before it lasted more than 10 times that... That said, a concentric slave will give far superior clutch action compared to the standard V4 set up.
