There are 3 different bearing sizes to choose from. Choose which size clutch you have below
1. 184/200 mm or + 10 mm extra long
This option fits all 184/200 mm clutches including Tenaci as well as other manufacturers.
2. 240 mm (only Tenaci clutches)
This bearing fits only the 240 mm Tenaci clutches.
3. 215-240 mm (not Tenaci clutches)
This bearing can be used for clutches from other manufacturers with sizes from 215-240 mm.
For 184, 200 or 240 mm clutches
Make sure that you use the correct clutch cylinder so the release bearing doesn’t get overfilled. This could lead to oil leaking on the rubber rings which would wear out the bearing. You could use 0,65″ but 0,75″ is recommended with pedal-stop. Or OEM-cylinder with pedalstop.
Also make sure that there is at least a 3 mm gap between the pressure plate and the bearing. When the discs wears out the gap is neccesery so that the clutch doesnt burn up.
Film about our bearings:
A positive clutch pedal stop must be used to prevent over-stroking the
hydraulic release bearing piston and the clutch. For access reasons, in many cars
it is not easy to determine how far the master cylinder is being stroked.
The method listed below provides a very effective method for adjusting the
1. Lift the drive wheels off the ground and support the car on jack stands.
2. With the engine off, place the gearbox in first gear and have someone
attempt to rotate the drive wheels.
3. Depress the clutch pedal slowly until the clutch disengages and the drive
wheels can be rotated.
4. Adjust pedal stop to allow another 1/4″ of pedal travel. This should provide
clean release of the clutch. Do not stroke the pedal any further than this
point throughout this procedure, otherwise you will over-stroke the clutch.
It is also recommended to install a bleeder outside of the bellhousing for bleeding out airbubbles.
