We change the oil in the gearbox after 20-30 thousand kilometers
We change the oil after the trip, while it is warm and has increased fluidity.
In addition, the particles of pollution will be in suspension.
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 12" 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 metal particles are visible in it, we flush the gearbox.
To do this, install the drain plug in place, cleaning its magnet from chips
Unscrew the filler plug with a "12" hex wrench.
Pour about 2 liters of a mixture of gear or engine oil with 20–30% kerosene or diesel fuel into the rear axle housing with an oil syringe and replace the filler plug
Substituting stops under the front wheels, hang out the rear axle.
Starting the engine, turn on the first gear.
After 2-3 minutes, completely drain the flushing oil (draining time is at least 5 minutes).
After cleaning the drain plug again, we wrap it in place.
Having unscrewed the filler plug, fill the crankcase with fresh gear oil with an oil syringe to the level of the filler hole, which corresponds to a volume of 2.2 or 3.0 liters (for a banjo bridge).
Rear wheel bearings are lubricated with gearbox oil.
To fill the hubs with oil, we alternately raise the right and left wheels by 30 cm with a jack and hold in this position for 6–10 minutes.
After that, we check the level and add oil to the gearbox.
