Fitting tipsBefore installing the disc onto the square gang axle, clean off all accumulated dirt, rust, and surface burrs from the shaft and spool spacers. Slide the notched blade into position ensuring the 49 mm dish concavity and cutting notches face the required operating angle of the gang assembly. Verify that the 26 mm square bore seats flush without excessive bind to eliminate localized stress points. Tighten the gang axle nut to the equipment manufacturer's specified torque and inspect the entire disc pack for tightness after the initial operational hours in the field.
