The air filter cartridge cleans the air as it comes into the engine. It will remove any particles and debris, keeping the engine free from buildup and problems. The air filter will become dirty and clogged with regular use and needs to be replaced as a part of routine maintenance. This is typically done once or twice a season, depending on frequency of use. It may be necessary to replace intermittently if there is an emergency issue. Air filters cannot be cleaned and should always be replaced with a genuine OEM replacement. This OEM air filter can be used with Briggs & Stratton engines in select lawn mowers and blowers from Toro, Husqvarna, and Briggs & Stratton. This pleated paper filter includes a plastic frame. The foam pre-filter cleaner is sold separately, and this cartridge is sold as an individual unit.

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.
