Over time, this vital part can become damaged, worn, or clogged, necessitating its removal for repair or replacement. Understanding the process of removing the auger from your Ariens snowblower is a skill that can save you time, money, and frustration.
This comprehensive guide will walk you through the entire process, from initial preparation to the final reassembly. We'll cover the tools you'll need, the safety precautions to take, and each step involved in safely and effectively removing the auger. By the end of this article, you'll be equipped with the knowledge to tackle this task with confidence, ensuring your Ariens snowblower is ready to face any winter storm.
Safety First: Essential Preparations Before You Begin
Before you even think about touching a wrench, prioritizing safety is paramount. Always disconnect the spark plug wire from the spark plug. This is a non-negotiable step that prevents the engine from accidentally starting while you're working on the auger, which could lead to severe injury. Ensure the snowblower is on a level, stable surface. If you're working in a garage or workshop, good lighting is essential to clearly see all components and fasteners.
Gather all the necessary tools and materials before you start. This typically includes a socket set with various sizes (common sizes for Ariens snowblowers include 1/2 inch, 9/16 inch, and 5/8 inch), a ratchet, an extension for the ratchet, a torque wrench, a pry bar or a sturdy flathead screwdriver, penetrating oil (like WD-40), gloves, safety glasses, and a container to hold removed bolts and hardware. Having everything readily accessible will streamline the process and prevent you from having to search for tools mid-task.
Consider the environment you're working in. If the auger is particularly stubborn or has been exposed to harsh winter conditions, rust and debris can make removal difficult. Applying a penetrating oil to the bolts and nuts that secure the auger assembly a day or two in advance can significantly ease their removal. Allow the oil to soak in, and reapply if necessary. This simple step can save you a great deal of effort and prevent the stripping of bolt heads.
Disassembling the Auger Housing: Accessing the Core Components
The auger is housed within the auger housing, also known as the gearbox housing or impeller housing. To access the auger itself, you'll first need to remove this outer shell. This usually involves locating and removing several bolts that secure the housing to the main frame of the snowblower. These bolts are often found around the perimeter of the housing. Take note of the location of each bolt, as they may vary in length or thread type. Using a magnetic tray or labeling each bolt as you remove it can prevent confusion during reassembly.
Once the exterior bolts are removed, you may need to gently pry the auger housing away from the frame. Sometimes, a bit of wiggling or a gentle tap with a rubber mallet can help break any seals or corrosion that might be holding it in place. Be careful not to force it, as you could damage the housing or surrounding components. If the housing is still firmly attached, double-check for any hidden bolts or fasteners you might have missed.
With the auger housing detached, you will now have a clear view of the auger assembly and the impeller (if your model has one). The auger is typically connected to the drive shaft, which is powered by the engine through a series of belts and gears. Before proceeding to detach the auger itself, it's a good time to inspect the condition of the auger housing, the impeller, and any seals or bearings for signs of wear or damage.
Detaching the Auger Blades: The Heart of the Operation
The auger blades are usually secured to the central auger shaft by a series of bolts. These bolts pass through the auger blades and into threaded holes or nuts on the shaft. The number of bolts can vary depending on the model, but it's common to find two to four bolts per auger blade. These bolts can be quite tight, especially if they've been exposed to moisture and debris. Use the appropriate socket and ratchet, and apply steady pressure. If a bolt is particularly stubborn, a few taps with a hammer on the end of the ratchet handle can help break the rust bond.
Once the bolts are removed, the auger blades may still be attached to the shaft by splines or a keyway. You might need to gently pry them off or tap them with a rubber mallet to loosen them. Be cautious not to bend or damage the auger blades during this process, as they are critical for performance. If the blades are heavily corroded, a bit more penetrating oil might be necessary.
After removing the auger blades, you'll be able to see the central auger shaft. This shaft is what connects to the gearbox or drive system. Inspect the shaft for any signs of damage, bending, or wear. Also, check the splines or keyway for any damage that could affect the secure attachment of new or repaired blades.
Removing the Auger Shaft and Gearbox Assembly
The auger shaft is typically connected to the gearbox at the center of the auger housing. This connection often involves a splined shaft that fits into a corresponding splined collar within the gearbox. To remove the entire auger shaft and gearbox assembly, you'll usually need to detach the gearbox from the main frame or the auger housing. This often involves a few bolts that secure the gearbox to the snowblower's chassis.
Once the gearbox is detached, you can then carefully slide the auger shaft out of the gearbox. This might require some gentle persuasion, as the splines can sometimes be a tight fit. If the shaft is proving difficult to remove, ensure all securing bolts have been fully removed and that there are no obstructions. A slight rotation of the shaft while pulling can sometimes help disengage the splines.
It's important to note that on some Ariens models, the auger shaft and gearbox might be a single, integrated unit. In such cases, you would be removing the entire assembly. When handling the gearbox, be mindful of any lubricants it may contain and avoid tilting it excessively to prevent leakage. Inspect the gearbox for any signs of oil leaks, unusual noises during operation (before removal), or worn gears.
Reassembly and Final Checks: Getting Your Snowblower Back in Action
Reassembly is essentially the reverse of the removal process. Begin by reinserting the auger shaft into the gearbox, ensuring the splines align correctly. If you're replacing the auger blades, attach the new ones to the shaft, making sure they are oriented correctly and that the bolt holes align. Tighten the bolts that secure the auger blades to the shaft. It's crucial to torque these bolts to the manufacturer's specifications to prevent them from loosening during operation. Consult your Ariens snowblower's owner's manual for the correct torque values.
Next, reattach the auger housing, ensuring all seals and gaskets are properly seated. Secure the housing with the bolts you removed earlier, again tightening them evenly in a star pattern to ensure a good seal. Finally, reconnect the spark plug wire. Before starting the engine, give the auger a manual spin to ensure it moves freely and doesn't bind against the housing or any other components.
After reassembly, start the engine and let it run for a few minutes. Listen for any unusual noises and observe the auger's operation. If everything sounds and feels normal, test the snowblower in a small area of snow. Pay attention to how the auger engages and clears snow. If you encounter any issues, immediately shut off the engine and re-examine your work.
