6.1.4. Dismantling and assembly of a transmission of type A and B

GENERAL INFORMATION

Gear wheels and shaft of transmissions of type A and B


1–primary 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 a reverse gear,
6–precision bearing,
7–lock ring,
8–the synchronizer 3 - it – 4-oh transfers,
9–the synchronizer 1 - oh – 2-oh transfers,
10-gear wheel of a drive of a speedometer.
Numbers of transfers of separate gear wheels are provided in black circles (by AR – a reverse gear)

Mechanism of gear shifting of transmissions of type A and B


1–lever of gear shifting,
2–draft of management,
3–selector,
4–forks 1 - oh – 2-oh transfers,

5–forks of a reverse gear,
6–forks 3 - it – 4-oh transfers,
7–plate of the mechanism of blocking

Dismantling of a secondary shaft

PERFORMANCE ORDER
1. To remove from a back part of a transmission an external ring of the precision bearing of a secondary shaft. To beat out from a back part of a case by means of a copper hammer completely secondary shaft.
2. To remove a lock ring from a synchronizer nave 3 - it – 4-oh transfers and to take a synchronizer ring, and also a gear wheel of 3 transfers.
3. To disconnect a gear wheel of the 2nd transfer and a lock ring of a persistent washer of a secondary shaft.
4. To remove a lock ring of a nave of the synchronizer 1 - oh – 2-oh transfers and to take a synchronizer nave.
5. To remove the synchronizer 3 - it – 4-oh transfers. To disconnect a nave of the synchronizer and its spring.

Assembly of a secondary shaft

PERFORMANCE ORDER
1. To insert a lock ring of a nave and the synchronizer 3 - it – 4-oh transfers. To establish crackers on a nave and to arrange opposite to each other cuts on both cones. To insert clamp and spring crackers. The bent ends of two spring rings it is necessary to arrange in one cracker.
2. To insert a spring ring of the synchronizer on a nave, the synchronizer 1 - oh – 2-oh transfers and to grease the synchronizer.
3. To establish on secondary to a shaft a gear wheel of the 1st transfer, and also the plug of the synchronizer and the oil deflector.
4. To define thickness of a spring lock ring of the precision bearing of a secondary shaft.
5. To establish a lock ring in a flute of a back part of a case of a transmission and to move it against the stop to an external ring of the precision bearing. To measure by a calliper distance between a surface of an emphasis of the bearing and the top surface of a flute of an adjusting ring. To subtract from result size width of the bearing for determination of thickness of a necessary additional ring. To pick up thickness of a ring from available spare parts (see subsection 6.1.1).
6. To fill a nest of the bearing of a secondary shaft with konsistentny greasing.
7. To press the bearing and to fix a lock ring.
8. To establish a gear wheel of a drive of a speedometer. The distance between a face-to-face surface of the precision bearing and a gear wheel of a drive of a speedometer should make (size A) 51,20 mm for a transmission of type A and 49,25 mm for a type B transmission.
9. To establish the synchronizer 1 - oh – 2-oh transfers. Adjusting signs on a nave and a ring of the synchronizer should settle down on one line. It is necessary to pay attention, that the sliding coupling with a gear wheel of a reverse gear was directed back.
10. To establish on a secondary shaft a gear wheel of the 2nd transfer together with a lock ring, a ring of the synchronizer and a persistent washer, and also a lock ring.
11. To establish on the press on a secondary shaft a ring of the synchronizer of the 3rd transfer.
12. To establish on the press on a secondary shaft a synchronizer nave 3 - it – 4-oh transfers, longer flange of a nave directed forward and to establish a lock ring.
13. To heat up a back part of a case of a transmission by immersion it in hot water and to establish a secondary shaft and a lock ring.

Dismantling and assembly of primary shaft, and also gear wheels of an intermediate shaft

PERFORMANCE ORDER
1. To remove from primary shaft a lock ring and the bearing by means of a press or a stripper.
2. To cover a landing surface of the precision bearing of primary shaft with universal greasing, to establish the bearing on the press and to insert a lock ring.
3. To remove by means of a screw-driver the sealing ring fixed in an external ring of the precision bearing of primary shaft. To fill the bearing with konsistentny greasing and to insert a sealing ring by means of the corresponding plug, condensing edge in the direction of a case of a transmission.
4. To take an axis of an intermediate shaft, the remote plug and 19 bearing needles (a type A transmission), and also persistent washers from two parties of the block of gear wheels of an intermediate shaft. Type B transmissions (the strengthened design) has on 21 bearing needles and have no remote plug.
5. To insert the block of gear wheels on an axis of an intermediate shaft and to fill from two parties space between an axis and an internal surface of an opening of the block of gear wheels konsistentny greasing. To insert a persistent washer, 19 or 21 bearing needle, the remote plug (a type A transmission) and the following persistent washer.
