How to Replace the Spiral Assembly in Troy-Bilt Snow Blowers

When you are using your Troy-Bilt snow blower, the snow is picked up and then blown out of the blower through the spiral assembly. The spiral assembly, which is also commonly known as the auger assembly, is literally a spiral metal piece in the front of the blower. If one of the spikes on the spiral assembly break or if you notice other broken parts, then you can manually replace the assembly. A new spiral assembly part can be ordered from the Troy-Bilt manufacturer or purchased from an online retailer.
