Disassembly of the synchronizer sleeve (Peugeot 405)

The sleeve of each synchronizer must be disassembled separately so as not to confuse their components. One of the stopper balls should be pressed into each of the bushings, which will allow the hub to be removed from the sliding bushing.

In the MA type gearbox, the springs and balls of the sliding sleeves of all synchronizers are the same, and the synchronizer stops of 1-2 gears are different from the others. Synchronizers of 5th and 3-4 gears are almost the same and differ in hubs - the hub of the synchronizer of 3-4 gears has a groove (on the opposite side of the groove on its sleeve), which is not on the 5th gear hub.
