<p>The invention concerns a method for detecting damping performance of a torsional damper (212) in a clutch disc (200). The method comprising the steps of registering a present value of a rotational motion characteristic of a gearbox shaft (105) and detecting damping performance of the torsional damper (212) by comparing the present value of the rotational motion characteristic with at least one of: - a predetermined value, - a stored value of the rotational motion characteristic of the gearbox shaft (105) registered when the torsional damper (212) was new, or - a registered present value of a corresponding rotational motion characteristic of a propulsion unit output shaft (104). The invention also relates to an arrangement for detecting damping performance of a torsional damper in a clutch disc.</p> |
