Regards Mario Vivera. In addition to what was indicated by the great master Luis38 (best regards), it would not be necessary to observe once the back cover of the washing machine cabinet has been removed if the two white plastic gears remain motionless when turning the pulleys during the washing and rinsing stages. in one sense and then in the other. They must remain immobile in those stages. Equally important is the presence of lithium-based grease on the inner faces of both gears for a very good lubrication of both the spring of two guides and the steel cylinder present there. Is the lower end of the adjustable screw present in the clutch arm in contact with the smooth surface of the brake arm at those stages that you have indicated or is there a separation of a couple of millimeters between both surfaces mentioned above? Comment on it. Thanks and regards.
