9.4.14. Dismantling and assembly of the leading shaft with coupling by K2 and the forward block of planetary gear wheels
Dismantling
Details of installation of components of the leading shaft with coupling by K2 and the forward block of planetary gear wheels
|
|
|
84 — the Internal support of coupling K1 with the integrated forward block of planetary gear wheels
84a — the Gear wheel
84b, 104, 106 — Lock rings
85 — the Persistent needle bearing
100 — the Conducting shaft with coupling of K2
101 — the Piston
|
101a — the Internal epiploon of the piston 101b — the External epiploon of the piston
102, 107 — Disk springs
103 — the Spring clamp
103a — the Epiploon of a spring clamp
105 — the Block of disks |

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove couplings of K1, K2 and K3.
3. Take a lock ring (84b) from an internal support of coupling K1 (84) and remove a gear wheel (84a) (see сопр. illustration).
4. Remove the conducting shaft with coupling of K2 (100).
5. Remove the needle persistent bearing (85).
6. Remove a lock ring (106) from an external support of coupling K2.
7. Remove the block of disks (105).
8. Remove a disk spring (107). |
| 9. Establish a stripper (076) on a spring clamp (103) and press on it until the lock ring (104) is not released. |
|
10. Remove a lock ring (104).
11. Remove a disk spring (102) and take the piston (101) from an external support. |

Assembly
Check of a gap between a lock ring (90) and an external disk (89c)
|
|
|
100a — the External support of coupling K2
101 — the Piston
105a — the External disk 1.8 mm thick
105b — the External disk thickness 3.5 mm thick/new is 2.8 mm
105c — the External disk 4.0 mm thick |
105d — Frictional disks
106 — the Lock ring
107 — the Disk spring
L — the Gap |
Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring (106) and an external disk (105c). The size of gaps in coupling
of K2 is specified below in the table. In case of need adjust a gap by selection of a lock ring (106) of the required thickness.
Rings 2.3, 2.6, 2.9, 3.2, 3.5 and 3.8 mm thick are issued
.
