Parts for Yard Machines 21AA40M1029 / 2010: .Quick Reference Parts

This is a small engine spark plug positioned in the engine cylinder head. It supplies the spark that will ignite the air-fuel mixture to enable an engine to produce power. This particular spark plug is designed with superior corrosion resistance and dependable performance. Small but mighty, this component allows for increased conductivity and heat control. If the spark plug is damaged or in poor condition, many problems may arise in equipment, including sudden stop while running, overheating, and excessive gas consumption. Replace the spark plug by disconnecting the spark plug wire first, then use a socket driver or wrench to remove the spark plug. Install the new spark plug by turning it by hand initially to avoid cross-threading. If it doesn't twist anymore, use a deep socket wrench or socket driver to tighten the plug until snug. The spark plug can also be used to tune up outdoor power equipment or improve a small engine. This part is recommended to be replaced once per season. This part works with lawn mowers, snowblowers, tillers, leaf blowers, log splitters, wood chippers, and others with small engines. It is compatible with brands such as Craftsman, Cub Cadet, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Bolens, Yard-Man, and MasterCut. This is a genuine OEM part directly from the manufacturer and is sold individually.

This is an idler pulley assembly for a snowblower or tiller. The idler pulley works together with other pulleys to drive the belt system in an engine. It regulates the belts connecting to the crankshaft to produce movement in various engine accessories. This is a genuine OEM part and is sold individually. This part is compatible with Craftsman, Cub Cadet, Huskee, Troy-Bilt, and Yard Machines. Over time, the pulley components wear down and begin to slip. Damaged bearing devices can also cause wear on the pulley, causing the engine to fail. To replace an idler pulley in a snowblower, remove the ignition key and disconnect the spark plug. Using a socket wrench, remove the mounting bolts securing the belt cover. If required, loosen the tension. Use a ?-inch socket to remove the lower bolts. Pull off the cover and use the wrench to remove the bolt from the pulley. Remove the old part and transfer the bushing into the new part. Position the new pulley, thread the bolt, and tighten. Per model, either realign the auger drive linkage on the bolt and slide on the push nut to secure, or realign and reset the tension spring. Then, recover and reattach.
