Which is the correct way to tighten mounting bolts during the installation of a pressure plate?

Tightening mounting bolts in a stepped pattern is crucial during the installation of a pressure plate to ensure even distribution of force across the assembly. This approach helps to prevent warping or misalignment of the pressure plate, which can lead to improper clutch operation or premature failure of components.

The stepped pattern typically involves tightening the bolts incrementally, alternating from one bolt to another rather than applying full torque to one bolt at a time. This gradual tightening allows each bolt to assume its load gradually, ensuring the pressure plate is seated evenly against the flywheel.

Using a single pattern would not achieve the same even distribution of pressure and could lead to issues like uneven wear or adhesion, while extreme torque can risk stripping the bolts or damaging the pressure plate. Relying solely on hand tools may not apply the necessary torque accurately, which is why utilizing a torque wrench is often recommended to achieve the specified torque settings.
