The ps650ksd-6-37 clutch is a key component of the drive system on RURIS diesel cultivators (models 650KSD and 651KSD). Unlike the centrifugal clutches on small machines, this is most often a multi-plate clutch assembly that must withstand the high torque of a diesel engine. Its function is to allow gradual and safe transfer of power from the engine to the gearbox, as well as complete disengagement of the drive when changing gear or stopping the machine. Technical specifications: Manufacturer: RURIS Catalogue number: ps650ksd-6-37 Compatibility: RURIS 650KSD, RURIS 651KSD (diesel variants). Construction: Reinforced housing with a set of plates with a high coefficient of friction, designed to work under the increased heat and vibration specific to diesel units. Advantages: The original RURIS clutch for the diesel series is designed to withstand the specific shock forces of a diesel engine. Replacement clutches of unverified quality often suffer from "slipping" when hitting hard ground, which leads to overheating of the gearbox and accelerated wear of the plates. The original guarantees precise disengagement, which directly protects the gears in the gearbox from wear when changing speeds.
