If you have the 1 inch square drive shaft that uses the "pin" or bolt to secure to the motor shaft and you keep shearing the pins or bolts, the solution is simple. The HOLE thru the Square tube MUST be 1/4 inch with NO OVAL wear on it. If you have any oval wear, when the motor engages, the little slip caused by the motor before the driveshaft engages acts as a cutting edge and cuts the bolt/pin. Also, you CANNOT have any threads engaged in this area as you need the full 1/4 shaft to prevent free play. The fix is to cut the ends off the square shaft(1 to 1.5 inches to remove the oval holes, drill a new 1/4 inch hole thru the square drive shaft and use the hardened pins/bolts that are designed for the drive shaft assbly. You CANNOT use standard 1/4 inch bolts as they will shear off. Doug
