FAQ

These shear pins and nuts are designed for snow throwers and snow blowers manufactured under the AYP, Sears, Craftsman, Murray, and Noma brands. Compatibility is determined by your specific auger system and model number, so please verify your original part number before ordering.
This kit replaces part numbers 1501216MA and 301172. It also cross-references with part numbers 722130, 9524MA, and 301172MA. Please verify the number used on your machine's parts list or check your old hardware before installation.
A shear pin is a sacrificial fastener that connects the auger to the shaft. If the auger strikes ice, a rock, or another hard obstruction, the pin is designed to break first to help protect more expensive components like the gearbox, auger shaft, or drive system.
Typical symptoms include one or both augers not turning while the machine is running, uneven snow throwing, an auger that spins freely by hand when the engine is off, or visible broken or missing pins and nuts. After hitting packed snow, ice chunks, or debris, checking the shear pins is one of the first inspection steps.
Replacement is usually straightforward and often takes about 10 to 20 minutes. In most cases, you will need basic hand tools such as wrenches or sockets to remove the old nut and install the new pin and nut. Always shut the engine off, remove the key, disconnect the spark plug wire, and clear any snow before working near the auger.
Shear pins usually fail because the auger contacts something it cannot easily pass through, such as frozen snowbanks, buried newspapers, gravel, branches, or chunks of ice. They can also break more often if the auger is partially seized from rust, if debris is wrapped around the shaft, or if the machine is forced into heavy packed snow too aggressively.
Yes. Inspect the auger holes for elongation or damage, ensure the auger turns freely on the shaft, and check for bent hardware, wrapped debris, or signs of gearbox stress. If one pin broke after a hard impact, it is recommended to inspect the opposite side as well and keep extras on hand for future snow season repairs.
