Periodically (but not less than once per 15,000 km of run) check the oil level in the manual transmission. The design of the gearbox 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 a different viscosity oil, when repairing a gearbox, etc.).
USEFUL ADVICE: It is recommended to drain the oil within 15 minutes after the trip, until it has cooled down and has good fluidity.
NOTE: In a manual transmission, use API GL4 SAE 80W-90 or SAE 75W-90 oil. The manufacturer recommends replacing the factory-filled oil with SAE 75W gear oil if the vehicle is operated for a long time at an ambient temperature below -30°C.
To check the oil level, top up or replace it in a manual transmission, perform the following operations.
1. Remove the crankcase protection (see «Removal and installation of mudguards and engine crankcase protection»).
2. Loosen the oil level plug located on the side of the gearbox housing and remove the plug.
3. The oil level should be at the edge of the hole or slightly below it (you can reach the surface of the oil with a screwdriver or your finger).
4. If the oil level is too low (cannot be controlled with a screwdriver or finger), remove the cap from the oil filler plug located on top of the shift housing...
5....loosen the plug...
6.... and turn it inside out.
NOTE: The oil filler plug doubles as a breather, so check that the holes are clean.
WARNING: It is forbidden to operate the vehicle without the protective cap of the plug! In its absence, road dirt will enter the gearbox.
7. Fill the oil with a syringe into the hole in the gear shift housing until it emerges from the control hole. Screw on the control hole plug.
GOOD ADVICE: There is a magnet in the cork to collect metal wear products, clean it before installing the cork.
8. Replace the oil fill plug.
9. An oil drain plug is not provided in the design, therefore, if it is necessary to change the oil, place an oil drain container under the gearbox, unscrew the bolts securing the lower gearbox cover...
10....and drain the oil.
11. Remove cover and gasket.
12. Wipe the cover and gasket with a clean rag to remove any remaining oil.
NOTE: Replace the gasket with a new one each time the bottom cover is removed.
13. Install the bottom cover of the gearbox and fill in the oil as you did when checking its level and topping up (see paragraphs. 1-7 of this subsection).
