We replace the oil in the gearbox after 20-30 thousand kilometers.
We change the oil after the trip, while it is warmed up and has increased fluidity
In addition, pollutant particles will be suspended.
Therefore, when draining the oil, these particles will be removed along with the oil.
Clean the breather screwed into the rear axle housing from dirt by turning its cap several times
Use a 12mm hex wrench to unscrew the drain plug
Drain the oil into a container with a volume of at least 3 liters.
If the oil is dark in color* or there are visible metal particles in it, wash the gearbox.
To do this, install the drain plug in place, clearing its magnet of chips.
Use a 12mm hex wrench to unscrew the filler plug.
Using an oil syringe, pour approximately 2 liters of a mixture of transmission or engine oil with 20–30% kerosene or diesel fuel into the rear axle housing and replace the filler plug
Putting stops under the front wheels, we hang up the rear axle.
Having started the engine, turn on first gear.
After 2–3 minutes, completely drain the flushing oil (draining time is at least 5 minutes).
Having cleaned the drain plug again, screw it back in place.
After unscrewing the filler plug, use an oil syringe to fill the crankcase with fresh transmission oil to the level of the filler hole, which corresponds to a volume of 2.2 or 3.0 liters (for a banjo axle).
The rear wheel bearings are lubricated with oil from the gearbox.
To fill the hubs with oil, jack up the right and left wheels alternately by 30 cm and hold in this position for 6–10 minutes.
After this, check the level and add oil to the gearbox.
