Hydraulic conversion
Next stage in procecdings is converting the type 9 to hydraulic clutch, I found a good scrapyard source of a master cylinder in the new shape Rover
45/400, I am going to try using the slave cylinder also but if that dosen't work I will shell out for a Saab 900 slave cylinder.
Any experiences ?

If you buy the SAAB cylinder your cheapest option is new from Europarts,try their website..
If you look in my photo archive you can see the SAAB cylinder fitted into my Toyota box...

Once I've finished a project why do I start another?

nice job
it looks good and easy
is this true
if so what slave cylinder fits the type 9 box and how much pedal travel do you need
sorry if this has hyjaked your thread trident but it looks like the answer to many of my problems
cheers dave

Darren at GTS has a an adaptor plate for the SAAB unit listed
Here are a couple of URLS I have found
http://www.partsforsaabs.com/product_info.php?cPath=86_89&products_id=1723
This one appears to use a series 3 Land-Rover/Hillman Imp slave I am not sure how it is mounted on the bell housing -- might even be welded on.
http://www.prepfab.co.uk/Parts/pages/hydbell_jpg.htm
The ideal slave cylinder mounting position will vary as Ford flywheeels vary and clutches differ.
What ever combination is used the point where the cylinder piston is fully home can be found by doing a dummy assembly with no clutch driven plate
under the pressure plate this will put the clutch thrust bearing as far backward as it will ever need to go (and some).
The critical bit is getting the stroke right, I have a rough figure for the cable travel when a Sierra clutch is depressed (if anybody else has
measured this I would appreciate the measurement), I am pretty sure if I go the Saab route it will just be a matter of using the same dia master
cylinder as a SAAB 9000, However I first intend to try using a conventional external slave cylinder so to avoid damaging the clutch pressure plate
by over stroking I am going to err on understroking the clutch which if it dosen't work I can always use a bigger master cylinder.

When I worked my travel out for the Toyota box I bolted the engine and box together with the clutch fastened up,and carefully measured the distance
using internal calipers up to the gearbox bearing plate and worked it out from there.
I think I allowed about 5mm freeplay before it touched the clutch fingers.
Don't forget the clutch fingers close in (or forwards ) as you tighten the clutch cover plate up.
On the Toyota box this worked out to need an adapter 15mm thick.
If you use a pedal stop there is no way you can overstroke and pop the cylinder out!

Go to http://www.whirl.demon.co.uk/locost/ and click on the link for "first half of 2002" and there's a bit of detail there about
installing the Saab clutch slave cylinder. Admittedly this is into a T-50 'box but the principles are the same - it'll just be the
dimensions that are different.
Like Dean says, bolt up the 'box to the engine with a worn-out clutch plate in place, then do it again with a new clutch plate and cover,
measuring each time the position of the clutch "fingers". Once you've got the length and travel of the Saab slave you can work out
how thick the spacer needs to be.
