AZ9231320745 middle axle main reducer differential assembly is OEM heavy-duty transmission component designed for Sinotruk HC16 tandem drive axles with a 5.73 gear ratio. All spiral bevel gears are forged from high-strength alloy steel and processed via carburizing quenching and precision grinding, which greatly improves wear resistance and load-bearing performance for mining and long-distance highway transport. The reinforced differential housing effectively avoids oil leakage, abnormal gear noise and shell cracking under full-load bumpy road conditions. Every finished reducer passes strict bench pressure and running-in testing before delivery. We supply genuine equivalent OEM replacement parts and premium aftermarket assemblies, supported by a 6-month quality warranty for bulk export orders to global heavy truck spare parts dealers.
