6.2.4. Dismantling and assembly of the block of gear wheels

GENERAL INFORMATION

Gear wheels and shaft of the mechanical five-speed transmission

1 – main shaft,
2 – secondary shaft,
3 – gear wheel of continuous gearing of an intermediate shaft,
4 – axis of the block of gear wheels of an intermediate shaft,
5 – axis of an intermediate gear wheel of the reverse gear,
6 – the synchronizer 3 - it – 4-oh transfers,
7 – synchronizer 1-oh-2-oh transfers,
8 – synchronizer of the 5th transfer,
9 – ball bearing,
10 – a nut of fastening of a gear wheel of the 5th transfer on intermediate to a shaft,
11 – speedometer drive gear wheel.
Numbers of transfers of separate gear wheels are provided in black circles (AR – the reverse gear)

Mechanism of gear shifting of the five-speed transmission


1 – shaft of management,
2 – selector,
3 – ring of the spring lock,
4 – forks 3 - it – 4-oh transfers,
5 – forks 1-oh-2-oh transfers
6 – forks of the 5th transfer,
7 – lever of turning on of the reverse gear,
8 – pin of the spring lock,
9 – spring

Dismantling of a secondary shaft

1 – sealing ring,

2 – gear wheel of the 1st transfer,

3 – ring of the synchronizer of the 1st transfer,

4 – synchronizer 1-oh-2-oh transfers



PERFORMANCE ORDER
1. To remove a lock ring from a synchronizer 3 nave - it – 4-oh transfers and to take a ring of the synchronizer and a gear wheel of the 3rd transfer.
2. To remove a lock ring and two adjusting half rings of a gear wheel of the 2nd transfer.
3. To remove a gear wheel of the 2nd eredacha from a vtoichny shaft.
4. To remove a speedometer drive gear wheel from a secondary shaft.
5. To remove the synchronizer and a gear wheel of the 5th transfer from a secondary shaft.
6. To remove a lock ring of the bearing from a secondary shaft and to take a secondary shaft from a middle part of a case of the transmission.
7. To remove a sealing ring, a gear wheel of the 1st transfer and a ring of the synchronizer of the 1st transfer from a secondary shaft (see rice. Dismantling of a secondary shaft).
8. To take the bearing of a secondary shaft from a middle part of a case of the transmission.

Assembly of a secondary shaft

PERFORMANCE ORDER
1. Before assembly to oil for the transmission of a surface of the interacting details.
2. In a middle part of a case of the transmission to install the bearing of a secondary shaft and to fix a lock ring of this bearing.
3. To establish spring rings on naves of synchronizers.
4. To establish a ring of the synchronizer of the 1st transfer and a gear wheel of the 1st transfer on a secondary shaft.
5. To establish on a secondary shaft a sealing ring by working edges in the direction from the bearing (see rice. Dismantling of a secondary shaft).
6. To install the bearing, a secondary shaft and a lock ring in a middle part of a case of the transmission.
7. To install the bearing, a secondary shaft and a lock ring in a middle part of a case of the transmission.
8. To establish a gear wheel of the 5th transfer, a sealing ring and the synchronizer of the 5th transfer on a secondary shaft.
9. To establish a speedometer drive gear wheel on a secondary shaft. To observe distance
And = 123 ± 0,5 mm.
10. To install on a secondary shaft the synchronizer 1-oh-2-oh of transfers. The flute (for forks) on the sliding coupling of this synchronizer has to be directed forward.
To establish a synchronizer ring, a gear wheel of the 2nd transfer and two adjusting half rings and a lock ring (in the drawing installation of a lock ring of the synchronizer 3 - it – 4-oh transfers is shown).
To establish on a secondary shaft a gear wheel 3-oh transfers, the synchronizer 3 - it – 4-oh transfers and a lock ring.
If the synchronizer understood, then at its assembly it is necessary to pay attention that the flute on the sliding coupling was directed forward.

Dismantling and assembly of the block of gear wheels of an intermediate shaft

Dismantling of the block of gear wheels of an intermediate shaft does not represent special difficulties. It is necessary to pay attention to losing needles of bearings and remote plugs (forward and back) needle bearings. At assembly it is necessary to install carefully two remote plugs and to cover needles of bearings with jellied lubricant that they did not drop out in the course of installation of a shaft of the block of gear wheels.
