In a snowblower, the driveshaft is connected to a part called a worm gear. The worm gear turns the auger blades which eject the snow. The worm gear is connected to the worm shaft, which causes the auger blade to turn rapidly. Eventually, the incredible torque inside the machine, plus the occasional bumps and bruises experienced by the machine in operation and when being stowed, may cause the worm gear to malfunction. When the snowblower is erratic in its operation and fails to remove snow completely, there is a good chance the problem is the worm gear. To replace the worm gear, remove the housing to get to the worm shaft. Remove the entire worm assembly. Next, remove the blower fan and remove the worm gear. Grease the auger assembly before installing the new gear. Reverse the order to reassemble. While the snowblower is disassembled, it's the best time so exam the auger, driveshaft, sheer bolts, and tires for wear. You may find other parts that need to be updated. Make sure to replace the worm bolt and any other necessary parts with a genuine OEM manufactured part such as this one. This gear can be used in a number of snowblowers, including machines made by Yard Machines, Craftsman, Bolens, Yard-Man, Troy-Bilt, Cub Cadet, Ryobi, Montgomery Wards, Huskee, and MTD. Part sold individually.

This is a simple extension spring with an outside diameter of 0.38 and a slack length of 2.5. It is primarily used as an extension spring for snowblowers, but may be compatible with other lawn equipment. It’s designed to apply tension as the throttle is applied. The more gas there is, the more resistance will be present. Under most circumstances, replacement is easy. When the spring breaks or gets rusty, look at both points of attachment. Memorize where it’s attached, or take a picture, and remove the old spring using a pair of pliers if necessary. Install the new spring and the tool is ready to use. This is an OEM part sourced directly from MTD, and it is sold individually. It’s black in color and was initially designed for Troy-Bilt lawnmowers. However, because this is a versatile part, it has since been repurposed for a number of MTD and related machines in other brands. These include lawn tractors and snowblowers, as well as lawnmowers, in brands such as Ryobi, Yard Machines, Husky, and Cub Cadet.

This genuine OEM replacement part is an extension spring for a Craftsman snowblower idler pulley assembly. The idler pulley attaches to a part of the snowblower's housing and is helps to transfer energy throughout the belt drive. This extension spring helps to redistribute some of the back-and-forth motion created in the pulley as the snowblower runs. This keeps the assembly from shifting out of place and potentially slipping. This extension spring is attached at two points and, if pulled in both directions too far, can eventually lose some of its tension. When this happens, the idler assembly can begin to shake and even slip out of place. Replacing the extension spring is an easy job that will only require a socket wrench to remove the idler pulley. A pair of pliers may help to remove the spring from its clips. This part is only compatible with Craftsman snowblowers and is sourced from its original manufacturer. It ships individually and any additional parts needed will have to be purchased separately.

This is a flat washer that can be used with bolts and screws on many kinds of lawn and garden equipment. Before a bolt can be fastened to a surface, a fastener needs to be inserted through the end. A washer can be used with these items to help distribute the load. Washers are also responsible for decreasing heat and friction while a fastener is tightened to a surface. Washers can also be used to offer electrical insulation or operate as spacers.Even though washers are made of durable materials, they can be damaged over time. If the shape of the washer is bent or cut in half, this indicates that it needs to be replaced. A socket wrench or screwdriver can be used to make the replacement. Remove the screw or bolt, remove the fastener, and add the washer to the fastener before it screws back in.This flat washer is a genuine OEM replacement part sourced directly from the manufacturer. It is compatible with lawnmowers, wood chippers, snowblowers, log splitters, tillers, chainsaws, and edgers by Craftsman, MasterCut, Cub Cadet, Turf King, Ryobi, Bolens, Husky, Montgomery Wards, Murray, Huskee, Yard Machines, and MTD.

Snowblowers are an essential bit of machinery for those who live in areas with heavy winter weather. The machines use an auger to turn and pull snow into the impeller assembly. The machines are typically self-propelled and must be put into gear to begin moving forward. This is done through a drive system that relies on a control lever and clutch cable that triggers the auger or wheels to turn. When that clutch cable is broken, the machine will not function. This replacement clutch cable is designed for snowblowers made by Craftsman, MTD, and other brands. It works with track, drive or traditional machines. This is an OEM replacement part that will require a nut driver for installation. It ships individually but includes all hardware necessary for a safe and effective installation.

This V-belt is a certified genuine OEM replacement part for a snowblower engine. A V-belt is essentially just a loop of rubber but it is one of the most essential parts of the engine. The V-belt loops around a series of pulleys, and as the drive pulley is turned by the engine, the V-belt transfers that motion and turns the other pulleys. This allows the engine to run more efficiently. While an engine is running, the V-belt is constantly in motion, meaning that it receives a lot of wear. Over time, the rubber material will begin to fray, and if left too long, it will eventually slip or even snap. If the V-belt breaks, the transmission will no longer run and the auger blades will not turn. Therefore, it is important to check the V-belt's condition frequently. As soon as it begins to fray, replace it using a set of socket wrenches. Be sure to follow the owner's manual as a guide for how to loop the new belt. This replacement V-belt is compatible with MTD, Troy-Bilt, and Craftsman snowblowers and it comes sourced from its original manufacturer. This part ships individually.

This is a 28 inch, left-hand auger spiral assembly, made of metal, that is used in snowblowers. This sleek, helix-shaped auger is the part of the snowblower that draws the snow inside the machine so it can then be propelled elsewhere. As this is a left-hand auger, it rotates differently than a right-hand auger.With normal snowblower use, these parts can become worn or damaged. A common cause of a broken or bent auger is when a snowblower hits a rock or other hard object hidden under the snow. This causes the auger to be incapable of moving the snow into the housing and through the chute. When this happens, the auger must be replaced. To ensure that the snowblower works properly, augers should be inspected regularly and replaced when found bent or broken. Replacing the auger is a process that requires a few steps. Unplug the spark plug to disable the machine, then remove the belt covers, drive pulley, and lastly the auger. This part is sold separately and is a genuine OEM part.
