The John Deere Doser DEF Pump (OEM RE553796) is an essential component in the diesel exhaust fluid (DEF) system, which helps reduce harmful emissions in compliance with stringent environmental regulations. This pump ensures that the correct amount of DEF is delivered into the exhaust stream, facilitating the conversion of nitrogen oxides into harmless nitrogen and water. Proper functioning of the DEF pump is critical for maintaining the efficiency and environmental standards of your John Deere equipment.
