Assembling the secondary shaft
The secondary shaft is assembled in the reverse order of disassembly.
Before assembly, lubricate the secondary shaft parts with a thin layer of transmission oil.
Make sure that when assembling the synchronizer blocks fit into the grooves of the blocking rings.
The ball bearing must be pressed onto the shaft, applying force only to the inner ring of the bearing.
