AYP, replaces part number 143651. Used on Craftsman, Poulan, Husqvarna, Wizard & More. Also replaces Husqvarna part number 532143651. Includes housing (137152), Shaft With Bearings (137553) and Hardware. Includes Hardware for mounting bolts (3 138776, 15772), Blade Bolt With Washers (850857), Spacer (129963) and Pulley Locknut (137266, 139729). Pulley is not included. The three mounting holes are pre-tapped for easier installation. Most replacement (and the FSP) 143651 spindles are not tapped and are more difficult to install. The top of the shaft is splined for spline type pulleys and the bottom of the shaft has the AYP 5 point star pattern. Very important when installing the pulley to put the spacer under the pulley (between the pulley and top bearing). If installed without a spacer or with the spacer on top of the pulley damage will occur to the shaft and pulley.
