Basic elements of the transmission: 1 – cover of gear wheels of the 5th transfer; 2 – laying of a cover of gear wheels of the 5th transfer; 3 – M10 bolt; 4 – plug; 5 – the directing pin; 6 – fork of inclusion of the 5th transfer; 7 – the sliding coupling of the synchronizer of the 5th transfer; 8 – nave of the synchronizer of the 5th transfer; 9 – spring; 10 – the blocking ring of the 5th transfer; 11 – gear wheel of the 5th transfer; 12 – needle bearing; 13 – M10 bolt; 14 – plug; 15 – the conducted gear wheel of the 5th transfer; 16 – bolt; 17 – sealing ring of round section; 18 – the directing plug with a sealing ring; 19 – drive flange; 20 – spring lock ring; 21 – plug cover; 22 – coupling case; 23 – gear shifting mechanism; 24 – bolt; 25 – the directing pin; 26 – bolt; 27 – spring lock ring; 28 – drive flange; 29 – bolt; 30 – the directing pin; 31 – plug cover

For dismantling of the transmission the special tool is used. Before dismantling of the transmission merge from it oil and carefully clear its external surface (fig. 8.8) .

You carry out dismantling of the transmission in the following order:

remove the release bearing and the lever of switching off of coupling;

turn off two bolts of fastening of the directing plug of the release bearing and remove it;

turn off bolts of fastening of a cover of gear wheels of the 5th transfer, uncover also laying of a cover a transmission case.

turn off two bolts of fastening of a fork of inclusion of the 5th transfer.

take the directing pin;

remove a fork of inclusion of the 5th transfer;

turn off bolts of fastening of gear wheels of the 5th transfer;

Transmission cases: 1 — a coupling case; 2 — a transmission case; 3 — a sealing ring of differential; 4 — the oil deflector; 5 — laying of a cover of gear wheels of the 5th transfer; 6 — a cover of gear wheels of the 5th transfer; 7 — a stopper of an opening of filling and check of level of oil; 8 — a magnet; 9 — an opening stopper for oil discharge

ATTENTION Depending on type of the replaced details it is necessary to execute adjustments.

record shaft from a provorachivaniye, having included at the same time back and fifth transfer by movement of the sliding coupling of the synchronizer of the 5th transfer;

weaken and turn off bolts of primary and secondary shaft;

turn off back and 5th transfers, having shifted the sliding coupling of the synchronizer of the fifth transfer down;

before installation of a stripper of a gear wheel screw M10x20 bolt in a carving opening of an end face of a main shaft — it will protect a carving from damage;

stripper remove a gear wheel of the 5th transfer of a main shaft;

turn out a bolt and take two directing pins;

remove sealing rings and if it is necessary, replace them with new;

remove a plouosa flange. For this purpose arrange under a flange mount or a steel plate and serially wrap two 8 mm of a bolt in carving openings on the opposite sides of a flange under the screw until the flange does not go out of the transmission. Apply adjusting tags on the right and left flanges of a half shaft;

remove a spring lock ring from a half shaft flange shaft. For this purpose fix a shaft in a vice with sponges from soft material and by means of a grip, remove old and establish new spring rings;

remove the gear shifting mechanism. Before removal of a shaft of the mechanism of gear shifting move it to the provision of idling, turn off two bolts of fastening and take a shaft from a case of the transmission (fig. 8.11) .

take the directing pins from a transmission case;

turn out a stopper of an opening of filling and check of level of oil from the transmission;

take a magnet from a case nest;

remove the speedometer drive from the party of an internal part of a case of coupling;

weaken and turn off bolts of fastening of a support of a secondary shaft (fig. 8.12) ;

Fig. 8.13. Arrangement of bolts of the holder of a shaft of inclusion of a backing: 1 — an external bolt; 2 — an internal bolt

weaken and turn off bolts of the holder of a shaft of inclusion of a backing (fig. 8.13) . The special tool is necessary for performance of this work;

turn off a bolt of fastening and remove a fork of inclusion of transfer of a backing and a returnable spring;

take a shaft of a gear wheel of a backing and an intermediate gear wheel and remove a backing gear wheel;

take primary and secondary shaft and differential from a case;

replace four epiploons providing tightness of connection.
