18.5. Working cylinder of coupling
Prevention
The brake fluid used in hydraulic system of coupling is poisonous therefore at its hit on skin it is necessary to wash out immediately this place a plentiful amount of water. If liquid got into eyes or in an organism, it is necessary to see a doctor immediately. Some liquids have property to ignite easily and can light up even from contact with hot knots of the car. Besides, the liquid used in hydraulic system of coupling dissolves paint and plastic therefore at hit of liquid on a paint and varnish covering of the car wash out it a plentiful amount of water. Also this liquid is hygroscopic, i.e. absorbs moisture from air and therefore the liquid which is stored a long time in open ware is not recommended to be used.

Removal
Removal of the working cylinder from a coupling case
| PERFORMANCE ORDER |
| 1. Lift a forward part of the car and record on supports. |
| 2. On the right side of the car install the corresponding container under the working cylinder of coupling. Unscrew the hydraulic coupling of the pipeline on the working cylinder of coupling and disconnect a hose. After discharge of liquid from hydraulic system of coupling close traffic jams the end of a hose and an opening in the working cylinder of coupling. |
| 3. Unscrew two bolts of fastening and remove the working cylinder from a coupling case (see rice. Removal of the working cylinder from a coupling case). Remove laying. |

Repair
Extraction of the piston from the working cylinder of coupling
Extraction of a spring from the working cylinder of coupling
| PERFORMANCE ORDER |
| 1. Clear the external surface of the working cylinder of coupling. Remove a lock ring and take a pusher from the working cylinder of coupling. |
| 2. Knock with easy blows of the hammer on the case of the working cylinder of coupling and take from it the piston and a spring (see rice. Extraction of the piston from the working cylinder of coupling, Extraction of a spring from the working cylinder of coupling). |
| 3. Carefully clear details of the working cylinder of coupling, check their state and, if necessary, replace them. The sealing ring of the piston needs to be replaced irrespective of its state. |
| 4. Remove an old sealing ring from the piston. Lower a new sealing ring in brake fluid and install it on the piston according to shooters. Check that the working edge of a sealing ring is before a spring on the end of the piston. |
| 5. Grease the channel of the working cylinder of coupling with pure brake fluid and establish a spring so that rounds of a spring of bigger diameter settled down from a back part of the working cylinder of coupling. |
| 6. Being careful, install the piston in the channel of the working cylinder of coupling so that the ledge of the piston entered a spring. |
| 7. Install a pusher with a dustproof cap in the channel of the working cylinder of coupling and fix by a lock ring. |

Installation
| PERFORMANCE ORDER |
| 1. Establish laying of the working cylinder of coupling so that the party with dredging was directed to a coupling case. |
| 2. Install the working cylinder of coupling with a pusher in a coupling case so that the pusher was established in spherical dredging in the coupling switching off lever. |
| 3. Fix the working cylinder of coupling by bolts. |
| 4. Connect a hose to the working cylinder of coupling, fill in liquid in hydraulic system of coupling and remove from it air. |
