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

Dismantling of a transmission carry out in the following order:

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

unscrew two bolts of fastening of the directing plug of the vyzhimny bearing and remove it;

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

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

take directing pin;

remove a fork of inclusion of the 5th transfer;

unscrew 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 plum

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

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

weaken and unscrew bolts of primary and secondary shaft;

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

before installation of a stripper of a gear wheel screw in a carving opening of an end face of primary shaft bolt М10х20 — it will protect a carving from damage;

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

turn out a bolt and take two directing pins;

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

remove a flange плоуоси. 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 leave a transmission. Put adjusting labels on the right and left flanges of a semi-axis;

remove from a shaft of a flange of a semi-axis a spring lock ring. For this purpose fix a shaft in a vice with sponges from a 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, unscrew two bolts of fastening and take a shaft from a transmission case (fig. 8.11) .

take directing pins from a transmission case;

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

take a magnet from a case nest;

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

weaken and unscrew 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 unscrew 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;

unscrew 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 from a case primary and secondary shaft and differential;

replace four epiploons, providing tightness of connection.
