The main gear drive pinion is manufactured together with the secondary shaft. The position of the shafts in the crankcase is fixed by adjusting rings 3 and 8, the thickness of which has three sizes: 1.86-1.89 mm; 1.94-1.97 mm; 2.01-2.04 mm. The differential is two-satellite. The driven gear 40 of the main transmission is fixed on the differential box 39. The gearbox control drive consists of a gear shift lever, a ball joint, a drive rod, an intermediate shaft, a gear selection rod and a gear selection and shift mechanism.
The five-speed gearbox has a longer primary and secondary shaft by about 50 mm, so the engine mounts and right side member are also modified. The engine is offset to the right by 17 mm, and the side member is bent outward opposite the crankshaft pulley. The front drive shafts are of a different length.
The speedometer drive pinion has 21 teeth. The driven pinion of the four-speed gearbox is 20 with 145 SR 13 tires, 21 with tires of other sizes, the five-speed type "K" is 20 with 145 SR 13 tires, 19 with 155 SR13, 175/70 SR12, 185/60 HR 14 tires. The filling capacity of the gearbox housing and the oil used are indicated in table 1.8.
