The oil level should be checked every 60,000 km.
When performing the following work, do not confuse the gearbox models, as they differ in tightening torques of mounting bolts, filling volumes, etc.
In the BE 3/5 gearbox, the oil level control plug in the gearbox is located on the outside (see illustration 3.0).
3.0 Holes and threaded plugs on the BE 3/5 gearbox housing.
1 - drain plug
2 - filler neck and hole for checking the oil level
3 - ventilation plug
To unscrew the plug, you need a square socket wrench.
To check the oil level in the gearbox, you need to unscrew the filler cap.

1. Insert your index finger into the filler neck hole. If your finger feels oil, then the oil level is normal.
To drain the oil, you need to unscrew the plug on the bottom of the box, under the main gear (see illustration 3.0). It is best to drain the oil when the engine is warm to improve fluidity.
To unscrew the drain plug, you also need the appropriate key.
2. Place a suitable container underneath and drain the oil. To ensure better oil drainage, it is recommended to unscrew the filler plug. After draining the oil, clean the drain plug and screw it back in place.
The tightening torque for the drain plug is 35 Nm, and for the filler plug - 22 Nm.
Other models of gearboxes have a hole for checking the oil level on the outside of the gearbox housing (see illustration 1.0b). Checking the oil level is performed in the same way as described above.
Draining oil from this type of gearbox is performed in the same way as described above. The tightening torque of the plugs of both holes is 30 Nm.
3. Fill the gearbox with approximately 2 liters of transmission oil of the appropriate specification. In this case, the oil level will be level with the lower edge of the oil filler hole. When filling the gearbox with oil on the BE 3/5 model, you can remove the vent plug (see illustration 3.0). In this case, when installing the plug, check the condition of its sealing ring.
