Rear axle

power take off on the tractor, reducing gear and drive transfer box of the front axle of tractors Belarus-92.

Gear shift mechanism

On the deck of gear shift casing (pic. а) is settled the gear shift mechanism. Gear change is realized by means of plugs, connected with flash welded pads 9. There are on the top pads places are diametrical holes that include spring-mounted balls 11, insuring plug fixing in defined position and inhibiting self-coupling of gears under load. Pass of gearing shifting is realized with lead 48, connected with bead 47, in which is fastened the plug 50, moving the gear 36. The plug pads are provided with splines that include the underside end of the shift lever 15, fixed in the cover 12 on the trunnion ball 14 by means of pin 17, that block the lever turn regarding vertical axle. The tractor gear shifts are equipped with device, blocking the starting engine operation by any switched gearing.
