Makita 240081-4 Spare Part - FAN 80 GA9020S/SMA910/M9001
Genuine Makita Fan 80 — part no. 240081-4. A direct replacement cooling fan designed to restore proper airflow to your grinder’s armature and prevent overheating during heavy use. The “Fan 80” designation refers to the fan size (about 80 mm outer diameter), so it matches the original cooling profile and mounting on compatible Makita armatures.
Fits (example models): Makita GA7020, GA7021, GA7031Y, GA7040S, GA9020, GA9031Y and GA9040S. The fan is supplied as the single fan element (ready to press onto the armature shaft in place of the worn unit); it installs in the motor/armature assembly without modification.
Why this part helps: a cracked, chipped or unbalanced cooling fan reduces airflow and can let the motor run hotter, causing brush and bearing wear or shortened motor life. Replacing the damaged fan with the original Makita part restores the tool’s designed cooling performance and keeps the grinder running reliably.
