John Deere 4.5L 4045 & 6.8L 6068 PowerTech Common-Rail Fuel Injector | Alliant Power AP52903 Remanufactured
Alliant Power AP52903 is a remanufactured Denso common-rail fuel injector for John Deere 4.5L (4045) and 6.8L (6068) PowerTech engines. It replaces John Deere RE546783, RE531210, RE530361, SE501928 and DZ100211, and Denso 095000-6320. Alliant Power lists it for machines such as the 310J, 310K, 310K EP, 310SJ and 410J backhoes, the 450J and 700J dozers, the 120D excavator, and the 5105M, 7130 and 7230 tractors.
AP52903 has a sibling, AP52902, for the same engine families. AP52902 is the Denso 095000-6310 version (John Deere RE546784, RE541425, RE531209, RE530362, SE501925). They are different parts with overlapping machine lists, so order by the number on your old injector. AP52903 is built with 100% new nozzles, end-of-line tested, and comes with its trim code, which must be programmed into the engine ECU.
Confirm Fitment Before You Order
AP52902 and AP52903 fit the same 4.5L and 6.8L engine families and even some of the same machines (the 410J is listed for both). Read the number on your old injector: RE546783, RE531210, RE530361 or 095000-6320 means AP52903; RE546784, RE541425, RE531209, RE530362 or 095000-6310 means AP52902. If you can’t read it, send us the engine serial number. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
