Additional Information

The snowblower oil seal 921-0145 fits around the shaft opening to keep oil contained inside the engine or gearbox and maintain proper lubrication.

If you notice oil leaking, puddling beneath the machine or residue collecting around the shaft area, the seal may be worn, cracked or no longer seated correctly.

Disconnect the spark plug wire before beginning the repair. Clean the area and press the new seal into place carefully; refer to your service manual if you need help aligning the seal during installation.
