This type of bearing is a wear item that requires periodic inspection and replacement to maintain proper operation of drive systems, cutting decks, and other rotating assemblies. Installation is typically performed by equipment technicians or experienced service professionals familiar with Toro outdoor power equipment.

The 109-3678 is intended for use in Toro lawn and garden applications where a direct OEM-style bearing replacement is required. This part is suited for service situations where the original bearing shows signs of wear, noise, roughness, or failure.
