The structure of the gearbox consists of:
- a gear casing, which contains and supports the main shaft and the layshaft, the rods, the forks and the gear selection and engagement device;
- a rear cover that contains the 5th speed gears;
- the plate retaining the main shaft and layshaft rear bearings;

- the planet gears and conical roller bearings and adjustment shims,
- the satellite gears,
- the speedometer idler gear.
