A pinion gear is a small cylindrical component that is integral with a rack and pinion mechanism. Together with the rack, its primary function is to transform rotational movement into linear motion. Machines like lawnmowers and lawn tractors have a rack and pinion system. When the steering wheel of a tractor is moved, the gear will rotate, which engages the rack. Although this component is exceptionally durable, it is still subject to wear and tear. Some symptoms of a bad rack and gear mechanism include a loose or tight steering wheel and a grinding noise. Performing a do-it-yourself rack and gear replacement is possible and takes only 30 to 45 minutes. If the rack is in good condition, but the gear is not, omly a pinion gear replacement may be needed. This brand-new, genuine Midwest Engine 695708 pinion ensures quality and compatibility with lawn tractors, generators, mowers, and engines from Midwest Engine, Briggs & Stratton, and Craftsman. The gear is sold individually. An original Midwest Engine Gear Ring is not included.

This brush retainer is part of the starter motor on many types of lawn and garden machinery. It comes with both the retainer and a set of four brushes.
