The TROY-BILT 918-07416A is a spindle assembly designed for use in residential lawn and garden equipment. The spindle assembly serves as the hub that holds and drives the cutting blade on a mower deck, transferring rotational force from the drive belt to the blade. This component is a direct replacement part intended for installation by small-engine equipment technicians or experienced DIY users performing deck maintenance or blade system repairs.
This spindle assembly is suited for residential lawn mower decks where the original spindle has failed due to worn bearings, a bent shaft, or impact damage. It is typically installed during seasonal maintenance or following a blade strike that damages the spindle housing or shaft. Refer to the equipment's parts diagram to confirm fitment before installation.
Designed as an OEM-style replacement spindle assembly for TROY-BILT lawn and garden equipment. Consult the original equipment parts diagram using part number 918-07416A to verify compatibility with your specific model before ordering.
Installation should be performed by a qualified small-engine technician or a knowledgeable equipment owner. Disconnect the spark plug wire before beginning any work on the mower deck to prevent accidental engine start. Remove the deck from the mower following the manufacturer's removal procedure before disassembling the spindle. Torque all fasteners to the equipment manufacturer's specifications as listed in the service manual.
