cylinder. The thrust bearing integrated into the release piston transfers the force to
the diaphragm spring of the clutch housing, thereby separating the positive
engagement between engine and gearbox.
NOTE
Also make sure to remove oil residues from your hands and the working environment
before handling the seal (this also applies to engine oil and other oils).
