This DEUTZ FL914 piston kit 0423 4939 is a complete piston assembly designed for the DEUTZ 914 series four-cylinder air-cooled diesel engines, commonly found in agricultural tractors, wheel loaders, and industrial power units. The kit includes one aluminum-silicon alloy piston with reinforced ring grooves, a set of three-piece chrome-plated piston rings (two compression, one oil control), and a fully hardened wrist pin with retaining clips. Unlike full overhaul kits which contain multiple cylinders, this single-piston solution is intended for targeted cylinder repair, partial rebuilds, or replacing a damaged unit without disturbing other cylinders. Each piston is machined to OEM-specified diameter, pin height, and skirt profile, then batch-tested for thermal stability. Compatible with original DEUTZ FL914 engine blocks without any bore modification.
