The basic work of repairing a five-speed gearbox is similar to repairing a four-speed gearbox.
Disassembly and assembly of a four-speed gearbox is described in the article - "Disassembly and assembly gearboxes VAZ-2107”.
Before inspecting the parts of the gearbox, thoroughly clean, remove all deposits with a brush or scraper and clean the holes and splines from possible contamination; then flush (with kerosene, thinner, etc.) to remove and dissolve any remaining oil.
The drive gear of the main gear is made integral with the shaft (shank) and is installed in the neck of the gearbox on two tapered bearings.
Disassembly of a partially synchronized gearbox
Disassemble in the following order:
Remove the side cover with the switch mechanism.
Remove the transfer case and clean it of dirt
Drain the oil from the transfer case.
The design of the gearbox is discussed in the article - Design features of the rear gearbox VAZ-2123
We wash and clean the gearbox from dirt and oil.
The transfer box VAZ-2123 is designed to change the amount of torque and distribute it between the front and rear axles.
