SHACMAN Transmission System Parts FAST 12JSD160T-1707140-2 Gearbox Auxiliary Box Synchronizer Assembly



The 12JSD160T-1707140-2 Gearbox Auxiliary Box Synchronizer Assembly is a transmission system component designed for FAST 12JSD160T manual gearboxes used in heavy-duty commercial trucks. This synchronizer assembly is installed in the auxiliary gearbox section and helps synchronize rotational speeds between transmission components before gear engagement, allowing smoother shifting operation and reducing impact caused by speed differences during gear changes. Public parts references identify 12JSD160T-1707140-2 as a FAST gearbox auxiliary box synchronizer assembly and associate it with heavy truck transmission applications, including SHACMAN, Foton Auman, and other vehicles equipped with compatible FAST gearbox systems. During long-distance transportation, heavy-load operation, and frequent gear-shifting conditions, the synchronizer plays an important role in maintaining transmission performance. When the original synchronizer shows signs of wear, difficult shifting, abnormal gear engagement, or reduced transmission smoothness, replacing the correctly matched synchronizer assembly can be part of the gearbox repair process. Before ordering, buyers should confirm the complete part number, gearbox model, synchronizer design, tooth specification, installation position, and transmission configuration to ensure compatibility.
