Fig. 204. Mechanism of switching of the transfer case:
1 – a rod of a fork of inclusion of a straight line and lowering transfers;
2 – a fork of inclusion of a straight line and lowering transfers; 3 – lock plate of rods; 4 – cap; 5 – case of the transfer case; 6 – rod of a fork of inclusion of the forward bridge; 7 – fork of inclusion of the forward bridge; 8 – pin; 9 – case cover;
10 – hatch cover; 11 – clamp rack; 12 – clamp spring; 13 – switching lever; 14 – lever of forks of inclusion;
15 – protective cover; 16 – pin; 17 – lever spring; 18 – lever case; 19 – plate of fastening of a clamp; 20 – clamp axis; 21 – clamp; 22 – ball clamp; 23 – ball clamp spring; 24 – screw


Distributing box two-level with the lowering transfer, mechanical, with one lever of switching (fig. 203, 204). The transfer cases used with five-step and the four-speed transmission, differ only with a case, the lever of switching and a glass of the bearing. The connecting plane of a case of the transfer case used with the four-speed transmission has inflow emphasis of the bearing of an intermediate shaft of the transmission.
