|
1 — the Support of external disks
2 — the Piston
3 — Pruzhina
4 — the Spring plug
5, 11 — Lock rings |
6 — the Internal disk
8, 10 — External disks
12, 13 — Sealing rings
020 — the Stripper
A — the Gap in coupling of K2 |

|
1. Remove a lock ring (11) from an external support (1) of external clutch plates.
2. Remove disks (6), (8) and (10). Check disks for lack of wear and damages.
3. Install a stripper (020) on the spring plug (4) and remove a lock ring (5).
4. Remove the spring plug (4) and springs (3).
5. Take the piston (2) from a support (1).
6. Remove sealing rings (12) and (13) from the piston (2). |

Assembly
|
|
| 1. Install sealing rings (12) and (13) on the piston (2). Track that sealing edges were not overwound and were established in the direction of an arrow. |
|
| 2. Install the plug (021) on a support (1), grease the plug (021) and sealing rings (12) and (13) gearbox oil, carefully install the piston (2) in a support (1), press the piston (2) without distortion, slightly turning it. |
|
3. Install the spring plug (4) and springs (3).
4. Install a stripper (020) on the spring plug (4) and establish a lock ring (5).
5. Establish disks (6), (8) and (10) in a support (1).
6. Establish a lock ring (11). |

Check of a gap
Check a gap
of "A". The nominal size of a gap
"And" in coupling
of K2 lies within
the range of 0.7-1.3 mm. Adjust a gap with way of a selection of a lock ring (11). Lock
rings 2.0, 2.5 and 3.0 mm thick are issued
.
