OakTen PTO-Clutch being designed to meet or exceed OEM specification. The purpose of the Clutch is to connect the crankshaft to the driveshaft to provide output power for work. When engaged, the clutch ensures two shafts are locked together and spinning at the same speed. Over time, the rotor and brake can wear down as they are engaged and disengaged, and springs can crack, which usually require a replacement of the whole clutch. When installing, ensure that the drive pulley is smooth, the clutch is properly torqued with enough clamp, and any wires are properly fastened. We offer you one year warranty and hassel-free return or refund for all the parts sold. Let OakTen Parts fix your equipment today!
