The input shaft is made as a single block of gears (except 5th gear), the secondary shaft is completely collapsible.
Thanks to the installation of two special diaphragm spring washers, one of which abuts against the outer ring of the differential bearing, it is not necessary to adjust the preload of the differential bearings.
The gearbox housing is filled with long life grease and does not have an oil drain hole.
Checking the oil level every 20,000 km of the car. The oil level should be at the level of the oil filler hole, or lower by no more than 10 mm.
