5. Installation Guide
Follow these steps to replace the paddles and scraper bar on your Toro snow thrower. This process requires patience and attention to detail.
Tools Required:
- Needle-nose pliers
- Socket wrenches (including a 7/16 combination wrench)
- Cordless impact driver (optional, for faster bolt removal/installation)
- #25 Star bit (Torx bit)
- Small spring clamps (optional, for holding paddles in place)
- Spray lubricant (optional, for bolt insertion)
Installation Steps:
- Prepare the Snow Thrower: Ensure the engine is off and the spark plug wire is disconnected. If tilting the unit, run the fuel tank dry. Place the snow thrower on a stable, elevated surface if possible.
- Remove Old Scraper Bar: Locate the existing scraper bar at the bottom of the snow thrower housing. Remove the bolts securing it and carefully detach the old scraper bar.
- Install New Scraper Bar: Position the new scraper bar (Part Number 55-8760) and secure it with the new mounting hardware provided in the kit. Ensure it is flush and tightly fastened.
- Remove Old Paddles (Rotors): Access the impeller housing. The paddles are typically secured by multiple bolts. Use your socket wrenches and #25 Star bit to remove the bolts. Note the orientation of the old paddles for reference.
- Prepare New Paddles: The new paddles (Part Number 99-9313) are made of hard rubber. If bolts are difficult to insert, a small amount of spray lubricant can assist.
- Install New Paddles: This step can be challenging due to tight spaces.
- Collars: Do not forget to place the collars in the holes where the paddle blades mount to the flat plate of the impeller.
- Securing Paddles: Use small spring clamps to hold the paddles in position while you align the bolt holes.
- Tricky Fasteners: For the two outside fasteners on the blades, which can be difficult to reach, try this technique: Fold a small piece of paper and place it in a box-end wrench. Secure the paper with a couple of pieces of blue tape. Place the nut into the wrench, then carefully maneuver it into position to start threading the bolt.
- Tightening: Use a #25 Star bit for effective tightening of the bolts. An impact driver can speed up the process, but ensure not to overtighten.
- Verify Installation: Once all paddles and the scraper bar are installed, double-check all fasteners for tightness. Manually rotate the impeller to ensure free movement and proper clearance.

6. Maintenance
Regular inspection and timely replacement of worn parts are crucial for optimal snow thrower performance.
- Inspect Paddles: Before each snow season, inspect the paddles for wear, cracks, or damage. Worn paddles reduce snow throwing distance and efficiency.
- Inspect Scraper Bar: Check the scraper bar for excessive wear. A worn scraper bar will not effectively clear snow down to the pavement.
- Hardware Check: Periodically check all mounting hardware for tightness. Vibrations during operation can loosen bolts over time.
7. Troubleshooting
If your snow thrower exhibits reduced performance after replacing the paddles and scraper bar, consider the following:
- Poor Snow Throwing Distance: Ensure paddles are correctly installed and not excessively worn. Verify that the engine is running at optimal RPM.
- Snow Clogging: Check for any obstructions in the auger housing. Ensure paddles are making proper contact with the housing.
- Snow Underneath Unit: A worn or improperly installed scraper bar can cause snow to be left behind. Ensure the scraper bar is correctly positioned and not excessively worn.
- Loose Parts: Re-check all mounting hardware for tightness. Loose paddles or a loose scraper bar can affect performance and cause unusual noises.
