Section 4 - REPAIR & ADJUSTMENTS
WARNING
DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Disconnect spark plug wire and secure away from spark plug. Engine and components are HOT. Avoid serious burns, allow sufficient time for all components to cool.
3.Slide driven disc assembly over to 1/8” from outside edge of drive disc. Maintaining the 1/8” measurement, remove any misalignment from the transfer rod linkage and the driven disc assembly anchor point. This can be done by loosening nut and rotating the transfer rod ball joint clockwise on the transfer rod until alignment with the driven disc assembly anchor point is achieved. Retighten ball joint nut. Insert ball joint into anchor point and reinstall the connector hex nut and tighten securely. See Figure 4.9. Move ground speed control to the first speed position, then back to the sixth speed position. Recheck the 1/8” measurement described previously. Reinstall driven disc spring to driven disc assembly.
