Replacing this crucial component can restore your snowblower's efficiency and save you from the back-breaking labor of manual shoveling.
This comprehensive guide will walk you through the entire process of replacing the auger on your Ariens snowblower. We'll cover everything from identifying the need for replacement to the final reassembly, ensuring you have the knowledge and confidence to tackle this essential maintenance task. By the end of this article, you'll be equipped to perform this repair yourself, saving money and extending the life of your valuable snowblower.
Diagnosing Auger Wear and Tear
The auger on your Ariens snowblower is subjected to constant friction and impact with ice and snow. Over time, this can lead to significant wear and tear. Common signs that your auger needs replacement include reduced snow-throwing distance, uneven snow dispersal, or a noticeable grinding noise during operation that wasn't present before. Visually inspecting the auger flights for chipped edges, bent sections, or excessive thinning is a primary diagnostic step.
Another indicator is if your snowblower starts to struggle with heavier, wetter snow. A worn auger loses its ability to effectively scoop and propel snow into the impeller housing. If you find yourself having to make multiple passes over the same area or if the machine seems to be pushing snow rather than throwing it, it's a strong signal that the auger's performance has degraded. Pay close attention to the sound of the machine; any new or amplified scraping or clanking sounds could point to a damaged auger or its mounting hardware.
Don't overlook the shear pins. While not part of the auger itself, these sacrificial bolts are designed to break if the auger encounters an immovable object, preventing damage to the gearbox and auger shaft. If you've recently sheared a pin, it's a good opportunity to inspect the auger for any underlying damage that might have caused the shear pin to break in the first place. Repeated shear pin failures without a clear obstruction can also suggest an unbalanced or damaged auger.
Gathering Necessary Tools and Parts
Before you begin the replacement process, it's essential to gather all the necessary tools and parts. You'll typically need a socket set with various sizes (common sizes include 7/16-inch, 1/2-inch, and 9/16-inch), an adjustable wrench, a torque wrench, a breaker bar, a pry bar, a wire brush, penetrating oil, and safety glasses. It's also highly recommended to have a helper, as some parts can be heavy and awkward to maneuver.
The most critical part is the replacement auger assembly. Ensure you order the correct auger for your specific Ariens snowblower model and year. You can usually find this information in your owner's manual or by checking the serial number on the machine against Ariens' parts lookup tool online. It's also wise to purchase new shear pins and nuts, as these are often replaced during the auger service. Consider replacing any worn or damaged drive belts or scraper bars at this time as well, as they are easily accessible.
Having a clean workspace is also crucial. Lay down a tarp or cardboard to protect your driveway or garage floor from grease and debris. Organize your tools and new parts so they are within easy reach. This preparation will make the entire process smoother and more efficient, minimizing downtime for your snowblower.
Step-by-Step Auger Removal
Begin by ensuring the snowblower is completely shut off and the spark plug wire is disconnected to prevent accidental starting. If your snowblower has a chute deflector, it's often best to remove it for better access. Next, tilt the snowblower forward onto its front edge or use a sturdy stand to lift the rear, giving you ample access to the underside of the auger housing.
Locate the shear pins that connect the auger shaft to the drive system. These are typically small bolts that pass through the auger shaft and the drive sprocket or pulley. Apply penetrating oil to the shear pin nuts and bolts and let it soak for a few minutes to loosen any rust or corrosion. Use a socket wrench to remove the nuts and then drive out the shear pins. You may need to use a hammer to gently tap them out. Once the shear pins are removed, the auger should be free from the drive mechanism.
With the shear pins removed, you can now detach the auger from the snowblower. The auger is usually held in place by bolts that attach it to the auger shaft or directly to the gearbox. These bolts can be difficult to access and may require a breaker bar to loosen. Carefully remove these bolts, supporting the auger as you do so, as it can be heavy. Once all fasteners are removed, you should be able to carefully pull the auger assembly away from the snowblower.
Installing the New Auger
Before installing the new auger, take the opportunity to clean the inside of the auger housing with a wire brush. Remove any accumulated snow, ice, or debris. Inspect the auger shaft and the gearbox for any signs of damage or wear. If the shaft appears bent or the gearbox is leaking oil, these issues should be addressed before proceeding. Lubricate the auger shaft splines with a suitable grease to facilitate installation and future removal.
Carefully align the new auger with the auger shaft and the mounting points. This can be a bit tricky, especially if you're working alone. Ensure the auger flights are oriented correctly, matching the direction of rotation for snow intake. Once aligned, reinsert the bolts that secure the auger to the shaft or gearbox. Tighten these bolts securely, but avoid overtightening, which could strip the threads or damage the components.
Finally, re-engage the auger with the drive system. Align the holes in the auger shaft with the corresponding holes in the drive sprocket or pulley. Insert the new shear pins and secure them with new nuts. Tighten the nuts firmly, but again, avoid excessive force. The shear pins are designed to break under extreme stress, so overtightening can compromise their function. Reattach any removed components like the chute deflector.
Testing and Final Checks
With the new auger installed, it's time for a thorough test. Reconnect the spark plug wire. Start the engine and let it run at idle for a few minutes. Listen for any unusual noises, such as grinding, scraping, or excessive vibration. If you hear anything concerning, shut off the engine immediately and re-inspect your work.
Gradually increase the engine speed and engage the auger. Test the snowblower in a small, manageable area with light snow if possible. Observe how effectively it picks up and throws snow. Check for consistent performance and proper chute direction. Ensure the auger spins freely and without hesitation.
After a successful test run, perform a final visual inspection. Check all bolts and nuts to ensure they remain tight. Look for any signs of leaks or damage that may have occurred during installation or testing. If everything appears to be in order, your Ariens snowblower is ready to tackle the winter snow with its renewed auger power.
