This essential maintenance task is more accessible than you might think. By following these step-by-step instructions, you'll gain the confidence to tackle this repair yourself, extending the life of your snowblower and ensuring its optimal performance when you need it most. We'll cover everything from gathering the necessary tools and parts to safely disassembling and reassembling your machine, empowering you to become a more self-sufficient snowblower owner.
Understanding the Auger Cable and Its Function
The auger cable is a critical component in your MTD snowblower's operation. It acts as the conduit between the control lever on your snowblower's handle and the mechanism that engages the auger, the rotating blades that break up and collect snow. When you pull the auger engagement lever, the cable transmits that force, typically by pulling a linkage or engaging a belt tensioner, to spin the auger. Without a properly functioning auger cable, the auger simply won't turn, rendering your snowblower ineffective for its primary purpose.
The wear and tear on an auger cable can stem from several factors. Over time, constant tension, exposure to the elements (moisture, salt, and extreme cold), and friction can cause the cable's internal wires to fray or break. The outer sheath can also crack or become brittle, allowing debris to enter and impede smooth operation. A cable that becomes stretched or develops kinks can also lead to poor engagement, making it feel loose or unreliable.
Recognizing the signs of a failing auger cable is key to preventing a complete breakdown during a snow event. Symptoms often include a lever that feels unusually loose, a lack of positive engagement when the lever is pulled, or the auger engaging intermittently or not at all. Sometimes, you might even hear a snapping sound if the cable has completely broken. Early detection and replacement will save you from a frustrating and potentially dangerous situation.
Gathering Your Tools and Parts
Before you begin the replacement process, it's crucial to have all the necessary tools and the correct replacement auger cable readily available. This will streamline the repair and minimize downtime. Essential tools typically include a socket set or wrench set (common sizes are 7/16, 1/2, and 9/16 inch), a flathead screwdriver, a Phillips head screwdriver, a pair of pliers, and potentially a wire brush for cleaning. Safety glasses are a must to protect your eyes from any falling debris or stray parts.
The most important part is the new auger cable itself. You'll need to identify the exact make and model of your MTD snowblower to order the correct cable. This information is usually found on a sticker on the snowblower's housing. You can often find the part number online through MTD's official website or reputable aftermarket parts suppliers. It's highly recommended to purchase a genuine MTD part or a high-quality aftermarket equivalent to ensure proper fit and durability.
In addition to the cable, consider having some lubricant on hand, such as a silicone spray or white lithium grease. This can be useful for lubricating pivot points and ensuring smooth operation of the new cable and related components. A small container or tray to hold removed nuts and bolts will also prevent them from getting lost in the snow or on your workshop floor.
Disassembling the Old Auger Cable
The first step in the disassembly process is to ensure the snowblower is completely powered off and the spark plug wire is disconnected. This is a critical safety precaution to prevent accidental starting. Next, locate the auger engagement lever on the handle assembly. You'll typically find that the cable is secured to this lever with a clip or a small bolt. Carefully remove this securing mechanism.
Once detached from the lever, trace the auger cable along the frame of the snowblower. It's usually routed through a series of guides or clips to keep it tidy and prevent it from snagging. You'll need to carefully release the cable from each of these guides. Pay close attention to how the cable is routed; taking pictures with your phone as you go can be incredibly helpful for reassembly. The other end of the cable will be connected to the auger engagement mechanism, often near the engine or the gearbox.
At the engagement mechanism, you'll find the cable end attached to a lever or a pulley system. This connection point will also have a securing clip, pin, or bolt that needs to be removed. Once all connections are freed, you should be able to pull the old auger cable completely out of the snowblower. If it feels stuck, double-check that you haven't missed any securing clips or that the cable isn't caught on any part of the frame.
Installing the New Auger Cable
With the old cable removed, you're ready to install the new one. Begin by carefully routing the new cable along the same path as the old one. Refer to your photos or your memory to ensure it follows the exact same route through all the guides and clips. This is crucial for proper tension and operation. Make sure the cable isn't twisted or kinked as you route it.
Once the cable is in its approximate position, connect the end of the cable to the auger engagement mechanism. This will involve reattaching the clip, pin, or bolt that secured the old cable. Ensure this connection is firm and secure. Next, attach the other end of the cable to the auger engagement lever on the handle assembly. Again, use the original clip or bolt to secure it, making sure it's properly seated.
After the cable is connected at both ends and routed through all guides, it's time to check the tension. The auger engagement lever should now feel firm and engage the auger mechanism positively when pulled. Some snowblowers have an adjustment mechanism for cable tension, often a turnbuckle or a threaded rod. If your lever feels too loose or too tight, consult your snowblower's manual for specific adjustment instructions. A properly tensioned cable will provide smooth and reliable engagement.
Testing and Final Checks
Before reconnecting the spark plug wire and attempting to start the snowblower, it's essential to perform a thorough visual inspection. Double-check that all clips, bolts, and fasteners are securely tightened. Ensure the new auger cable is routed correctly and isn't rubbing against any moving parts or the frame in a way that could cause premature wear. Verify that the cable moves freely when you operate the engagement lever by hand.
Once you're confident in your work, reconnect the spark plug wire. Start the snowblower and allow it to run for a few minutes. While it's running, carefully operate the auger engagement lever. You should feel a distinct "click" or resistance as the auger engages, and the auger should spin smoothly. Disengage the lever and confirm that the auger stops spinning. Test this engagement and disengagement cycle several times to ensure consistent operation.
If everything functions as expected, you've successfully replaced your MTD snowblower's auger cable. It's a good practice to lubricate any pivot points on the engagement lever and mechanism while you have everything accessible. This will contribute to smoother operation and longevity of the new cable and related parts.
