t  For noise optimisation, a plastic disc -B- may have been affixed to the drive plate of the pulley -A- → Parts catalogue. This plastic disc -B- reduces the rattling (castanet-like) noise which can occur at the pulley particularly in the case of vehicles with diesel engine in air conditioner “Econ mode” (in air conditioner full-load operation the noise is scarcely audible).
