100-5747 Toro Lawn Mower - Overview

This oil seal is an OEM replacement part designed to prevent oil from leaking from the engine or gearbox while keeping contaminants from entering. It is used in various lawn mowers where it ensures that the moving parts in the mower remain adequately lubricated and protected from dirt/debris. The oil seal can wear down due to aging, heat,...Read more pressure, or improper installation. If the seal is no longer functioning oil will leak, the engine will overheat, and its internal components will wear down due to excessive friction. Use seal pullers to remove the seal from its housing on the engine crankshaft or transmission housing. Clean the surrounding area using a cloth or soft brush to prevent contamination and ensure a good seal. Apply oil to the lip of the new seal and firmly press into position until it is flush against the sealing surface. Once you have completed the repair, run the lawn mower to check that there are no longer any leakage or performance issues.
