The clutch housing is attached to the front of the gearbox housing.

A stamped steel cover is installed on the rear of the gearbox housing.

The control drive of a manual transmission consists of a gear lever link with a ball bearing mounted on the base of the body, two cables, gear shifting and selection, as well as a mechanism installed in the gearbox housing.

The shift and select cables are structurally different from each other and are not interchangeable.

The main gear is made in the form of a pair of cylindrical gears matched according to noise.

Torque is transmitted from the final drive gear to the differential and then to the front wheel drives.

Bevel differential, four satellites.

The tightness of the connection of the internal hinges of the front wheel drives with the differential gears is ensured by oil seals.

Checking the level and topping up the oil in the gearbox

Periodically, but at least once every 15,000 km, check the oil level in the manual transmission.

The design of the manual transmission does not provide for oil changes during the entire life of the vehicle.

However, sometimes the need to change the oil may arise, for example, when switching to an oil of a different viscosity, when repairing a gearbox, etc.

It is recommended to drain the oil within 15 minutes after the trip, until it has cooled down and has good fluidity.

Pour API GL4 SAE 75W-85 oil into the manual transmission.

You will need: socket head or key "17", syringe.

The filler plug is located at the front of the gearbox

Unscrew the control hole plug

The oil level should be at the edge of the control hole or be slightly lower (you can reach the surface of the oil with your finger or a screwdriver).

If the oil level is very low (cannot be checked with a screwdriver or finger), you need to add oil.
