Post 1996, 9000 failure
Posted by c.k.christacopoulos (more from c.k.christacopoulos) on Wed, 8 Aug 2001 15:04:33
Hi (sorry to be posting a 2nd time, separate problems),
I seem to be discovering that there is a very costly fault in 9000s with manual transmission. The problem supposingly affects 1996 models onwards as the component(s) in question was modified.
The component is the flexible rubber pipe connecting the metal pipes for the clutch hydraulics. It is located above the gearbox and it is permanently fitted to the metal pipes between gearbox and master cylinder. Supposingly the pipe breaks down internally and releases pieces of rubber which subsequently EITHER block the valves on the slave cylinder (inside the gearbox) OR damage the seals of the slave cylinder. End result is that the clutch pedal goes solid refusing to be pressed or to return after pressed. With sufficient force the pedal gets pressed down and at one (un)lucky press the rubber pipe comes off the metal pipes and that is that.
I do not know if I believe the story as my slave cylinder was stuck open and when I pressed for a 2nd time the pipe was disconnected. Conveniently the SAAB dealer dispossed of all removed parts before I could inspect them. There was no loss of fluid prior to the damage which in any case should have been seen as the car was serviced a week earlier (or it never gets checked).
According to the dealer some cars can be bled others cannot. Mine could not be bled, so the repair was a new pipe kit, new slave cylinder (gearbox has to come out) and a new master cylinder in case it had contaminated fluid. For good measure I asked for a new clutch kit, total cost 630 UK pounds (give or take 1000 US dollars).
Can anyone tell me how do these slave culinders fail? Where is the design fault? The car is a 1997 model with 49k miles, neither mileage or time is enough for components to deteriorate to this extent.
Finally, the problem occurs on warm(er) days, the dealer that repaired my car had another one with the same fault on the same day and one more within a couple of days. Only one of the three bled. I am convinced SAAB knows of the problem (as the dealers know of the remedy) but is doing nothing about it. Any comments or previous knowledge will be appreciated.
TIA. Charles

Hi Chaps
Here I am touring in deepest France and the a/c pump is making ominous noises. I think its about to have a bearing failure. My question is, there being but 3 saab garages in france and about 5 saabs on the road ( I joke, but they are rarer than hen's teeth out here), if it goes (worse case seizes) shall I just cut its drive belt away (I have no tools with me and its a long way between towns) and do without it? That should let me continue on my merry way shouldn't it? Wont cause further problems?
9000 CDT 1989
Thanks
Nick
