5. The only regular procedure required is an oil change. There is no way to check the oil level in the gearbox or in the main gear housing, so the oil must be drained completely and then the amount of oil recommended in the gearbox must be added Specifications.
6. In addition to regular (scheduled) oil changes, it is necessary to change the oil in a new or reconditioned transmission after the first 1,500-2,500 km of mileage, as well as after work to eliminate a detected leak, since in this case the level of oil remaining in the transmission will also be unknown.
7. Please note that the gearbox has 2 drain plugs: one for the gearbox housing and the second for the final drive housing. When draining the oil, it is necessary to remove both plugs.

8. Fresh oil is poured into the box through the filler hole (see photo). Remember to measure out the required amount of oil in advance.

9. From October 1987 onwards, the filler plug on the gearbox can be used to check the oil level in the gearbox itself and in the final drive housing, so that oil can be topped up as necessary. There is only one drain plug, and it is located on the main gear housing. Oil is drained using this plug.
