You are supposed to have
approx 1/4′′
of free play between the throwout bearing and the fingers on the pressure plate. With the pedal to the floor there should be approx 0.050′′ of clearance between the disk and the flywheel or pressure plate (the disk is against one or the other).
How far do clutch fingers travel?
Most clutches call for a maximum gap of
1/16′′ to 1/8′′
. A common mistake is to allow too much gap or too little gap. Do it once, do it right! If you have too little gap, the throw out bearing will constantly be wearing the fingers of the pressure plate.

How do you measure throwout bearing clearance?
Why it is sometimes necessary to adjust a clutch actuation system?
Anything less than the correct amount o free play (or clearance ) will result in clutch slip, because the pressure plate will be unable to exert its full pressure on the friction plate
. Failure to cure this fault will quickly lead to a burned-out friction plate, and possibly a ruined pressure plate.
How do you test a slave cylinder?
- Open the hood. Locate the slave cylinder. …
