This part is a replacement push cap. This is a genuine OEM part made by MTD and has been sourced directly from the manufacturer. If the current push cap is broken or has been misplaced, this part can be used as a replacement. It is intended for use with several lawnmower models.The push cap is attached to the wheel hub cap and fits over the end of the axle shaft. This helps to protect the end of the shaft and the attached bolt that holds the wheel into position. When working on or near an engine, always ensure that the equipment is powered off and completely cooled down before attempting to undergo any repairs. For more accurate information on how and where to install this push cap, the appropriate owner's manual and equipment diagrams should be referred to. This push cap is suitable for use on a variety of lawnmower models manufactured by MTD, Yard Machines, Craftsman, Yard Man, and Troy-Bilt. It is a genuine OEM part and thus is made of high-quality, durable materials. This part is sold individually.
