Spindle asm
Did you know that many riding mower spindle assemblies use self-tapping screws to secure the spindle to the mower deck? This means the screw holes in the spindle mounting base are not threaded and the self-tapping screws will create their own threads when the base is being secured. Repair Clinic recommends you purchase new self-tapping screws when installing a new spindle assembly that requires them. We also recommend pre-threading the screws into the spindle base ahead of time to make it easier when you actually secure the assembly to the deck. Keep in mind, pre-threading these screws will require some effort. To find the right spindle components for your equipment, enter the full model number of your riding mower into Repair Clinic’s search bar, then select “Spindle” from the part category filter followed by the relevant part title.
