The differential is connected to the gearbox. It is mounted on two tapered bearings between the buildings clutch and gearbox. Two different diameters gland seal output shaft places outside. The leading differential gear is fixed in the casing and connected to the gear shaft drive wheels.

For the lubrication of parts of mechanical gear boxes provided long-term synthetic oil. Unlike the engine oil in the gearbox almost spent. If the outside of the gearbox no traces of water stains of oil, which means that its level is not decreased. Nevertheless, the oil level from time to time to check. An automatic transmission hydraulic fluid level can be checked only in the main transmission, the level in the gearbox must be checked for STOA with special diagnostic equipment.

Inspection and maintenance

Oil can flow out because of the leaky gaskets. Check the connections at the following locations: - Between the gearbox and engine; - Place output shaft of the gearbox; - Cork filler; - Plug the drain holes. All gear transmission nodes have very long service life. If the box fails, it must be repaired in TechCentre, as the repair should be performed by qualified professionals with a special tool. If you decide to undertake the repairs yourself, remember that the quality of repair gear needed orderly and very clean job. In addition to repair would require a special tool.

NOTICE Cork monitoring holes in the front of the gearbox should not turn away.

NOTE Transmission oil, blended for verification can be reused. New transmission oil should be used with care. Before discharging gear oil should be warmed up to operating temperature.

Withdrawal

Remove the bottom cover of the engine compartment, if it is installed. Check the bottom of the pan.

Loosen the oil drain bolt (Figure 3.30).

NOTE Control rod (Figure 3.30) can not turn away.

Let the transmission oil drain for about 10 minutes.

Top up gear oil until it will flow from the control holes (Fig. 3.31).

The level of transmission oil

All gear, except for M20 / M32, after repairs must be completed before the bottom of the control holes. Since gear oil is poured on the plant, by weight, the liquid level - always below the reference holes, during the interval of maintenance of correction is not needed if there is no leak.

NOTE Despite the fact that the transmission fluid completely blended, in the box is still approximately 0.2 liters. In this case, the filling volume of the gearbox M20 / M32 - 2.2 liter. If you installed new box, you need to pour 1.8 liters of liquid, as in a factory in the new box is filled with approximately 0.68 liters. oil.

Tighten the stopper control point 30 Nm

NOTE Use a new plug.

Replace the battery pack. Install support battery. Attach the bottom cover of the engine compartment, if it is installed Program volatile memory.
