Description
Item Name: Driving Axle Differentials NSN: 2520-01-574-4828 Part Numbers: AM General, LLC (CAGE: 34623) P/N 6048217 or Dana Light Axle Manufacturing�(CAGE: 63ZH0) P/N 2011412-1 Quantity:� 64 (with 100% Option) End Item: High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) Description: The rear differential connects to the transfer case or transmission via the driveshaft.� This system lets the engine power transfer to the HMMWV's rear wheels.� The differential distributes equal amounts of torque to both wheels.� This permits the wheels to react to resistance or provide traction for vehicle turns. NSN 2520-01-574-4828 is for the rear differential used in the HMMWV with a serial number of 300,000 or greater.� HMMWVs with a 300,000 or greater serial number are also referred to as a Revision B model (Rev B). This designation is indicative of reliability improvements that were implemented into the HMMWV during production to restore some reliability and performance to the vehicle through automotive improvements.� In this case, The Revision B rear differential is cooled by water provided from the engine coolant system whereas older models were cooled with oil or not cooled at all.� The reason that this water cooled variant provides an improvement over previous iterations is that we tied the cooling system into the vehicle Radiator/Fan system which allows for greater heat rejection and prevents thermal soak of the cooling fluid.� The improvements realized in this variation of the HMMWV differential have improved the vehicle reliability by lowering the operational temperatures of the differential fluid in the differential, driving axle which has a direct impact on the longevity of the component. While there is a Government�drawing for the Rear Differential, the drawing is not fully defined and does not include vendor developed components that were considered the intellectual property of the developer.� As such, the Government does not have the technical data package (TDP), detailed drawings, or performance specifications for these items.��
