Is the Sensonic clutch even hydraulically actuated? I don't think you'll find anything in the Haynes about bleeding the clutch since most 900's, if not all, were factory fitted with a cable clutch. If it is in fact hydraulic, find the bleed nipple on the clutch (where it might be I do not know), and then use a vacuum style bleeder. I'd put a bit more research into this though, don't take my words for exact science. Their may be more to it then what I'm saying.
i hope this means more to you than it does me :roll:
1] remove the battery
2]remove the clutch actuator unit's cover and check that the worm gear is in the engaged position (position E) ?
if the clutch actuator unit's worm gear is not in the engaged position, he worm gear should be rotated to the engaged position by means of a torque wrench set at 20nm
3]bleed the system like an ordernary hydrolic system (pressure bleed it)
4]connect the battery temperaraly
5]the gear lever should be it neutral. turn the ing' switch to the ON position and back to the OFF position again, wait about four seconds, the clutch actuator unit should now have moved to the engaged position (position E). repeat this procedure about 5 times to be sure that the system is properly bled.
6] remove the battery
7]apply a torque rench set to 20nm to the worm gear and turn it from the engaged position to the disengaged position and back to the engaged position again, if the system has been propery bled the worm gear should stop dead when the torque wrench is released, what ever its position
if the worm gear moves by itself to either of the end positions, this is an indication that air is present in the system. bleeding of the system must then be carried out afresh.
8]fit a new protector cover with sealant (loctite thread locking adhesive 577, part no 74 96 284) the cover must be completly water tight.
9] fit the battery
10]drive the car on test, changing gear frequently, and adapt the slip piont.
to do this
1]drive the car for atleast 4 minuits and change gear frequently. do not switch off the engine.
2]stop the car and put the gearlever in neutral.
3] wait 20 seconds with out touching the gearlever or throttle pedal
