8.1.19. A distributing box of system of a drive 4 х 4

THE GENERAL DATA

Elements of a distributing box

1 – a distributing box, 2 – a top arm, 3 – a sealing ring, 4 – a sealing ring of a forward right semiaxis, 5 – the intermediate back bearing,

6, 7 – a round sealing ring, 8 – a sealing ring of a back exit of a drive, 9 – a closing plate, 10 – driving a back connector, 11 – the index of level of oil

The distributing box is in an axis of forward power shafts, behind the engine. It provides distribution and management driving the moment on back wheels by means of planetary interaxal differential. This constructive decision makes moment division in the following proportion: 53 % on forward wheels and 47 % on the back. Forward driving the bridge with classical differential divides the moment between two forward wheels. Thanks to electromagnetic blocking there is a rigid connection of intermediate planetary transfer.

Box type: ТК2А.

Removal of a distributing box

Fig. In: V – a drain stopper, 1 – a back arm of the engine,

Fig. And: 2 – a flange of the terminator of moving

The distributing box acts in film from below the car.

Removal

PERFORMANCE ORDER

1. To merge oil from a distributing box and a liquid from cooling system. 2. To remove power shafts. 3. To remove the top element of fastening directing the index of level of oil of a distributing box. To take directing the index of level of oil from a distributing box. 4. To unscrew bolts of fastening of the bearing of the stabilizer and fastening bolts картера steering transfer to a forward cross-beam. 5. To remove a clip of connection of the bottom arm of the engine. 6. To unscrew bolts of fastening of the engine of blocking of interaxal differential. 7. To remove an axis of the terminator of moving. 8. To unscrew bolts of fastening of a cross-beam of the engine, preliminary having established below a telescopic support. 9. To take a cross-beam (it is necessary for making together). 10. To remove the terminator of moving and its clip. 11. To establish a steel core so that to avoid loss of a forward part of a power shaft, and then to unscrew bolts of fastening of a forward flange to a connector of an exit of a drive. 12. To take a power shaft (it is not necessary to separate a forward part of a shaft from the intermediate bearing since it causes balancing loss). 13. To neutralise action automatic натяжителя a blocking cable, having turned it on a turn quarter. 14. To take a cable of management of the engine of blocking of differential. 15. To remove management of a transmission. 16. To remove the case of an input of water in the block of cylinders. 17. To disconnect from a distributing box a cable of a drive of a speedometer. 18. To establish under a distributing box a telescopic support (to enclose wooden брусок). 19. To remove the top element of fastening of a distributing box. 20. To disconnect a socket of a control bulb of blocking of differential. 21. To remove the right arm of a distributing box and to unscrew bolts of its fastening to a transmission. 22. To take a distributing box on the right side.

Installation

PERFORMANCE ORDER

1. Installation consists in performance of actions in return sequence in relation to removal process. It is necessary to pay attention to that a distributing box to establish together with new sealing rings, to grease a place of a support of a shaft of the left power shaft with greasing Molykote BR2 Plus, to establish new self-locking nuts, to grease bolts of a back power shaft with greasing Loctite, and all болтовые connections to tighten the corresponding moment. 2. To fill in the oil, cooling liquid and to remove air from cooling system, following recommendations about use of operational liquids (subsection 2.1 see).

Repair of a distributing box

To replacement are subject only уплотнители and sealing rings as only they are accessible as spare parts.
