8.2. Hydraulic system of the drive of switching off of coupling
Prevention
When carrying out pumping use only new hydraulic liquid.
Before pumping check all tubes and reliability of connections.
Pumping valve arrangement
|
The valve of pumping is located on the right side of the transmission. |
Main method of pumping
PERFORMANCE ORDER |
1. Fill a tank with new hydraulic liquid. |
2. Remove a cap from the pumping valve. Put on a hose the valve and lower the second end of a hose in hydraulic liquid. |
3. Ask the assistant to squeeze out a coupling pedal. Open the valve of pumping and merge liquid. Close the valve. Release a coupling pedal. |
4. Repeat this operation while in the following liquid there is no vial of air left. |
|
Pumping with use of a set with the unilateral valve
PERFORMANCE ORDER |
1. In a rubber tube of such set the unilateral valve preventing hit of air and old hydraulic liquid back in system is installed. Capacity for collecting old hydraulic liquid can be also included in the package. |
2. After connection of a set to the valve of pumping open the valve. Smoothly squeeze out a pedal of coupling and slowly release it. Repeat this operation until all air is removed from hydraulic system. |
|
Pumping with use of a set for pumping under pressure
PERFORMANCE ORDER |
Having connected a set for pumping under pressure to a tank of hydraulic liquid, for pumping of system it is rather simple to open the pumping valve for a slitiya of old hydraulic liquid and production of air. |
|
All methods
PERFORMANCE ORDER |
Upon completion of pumping wash away the spilled hydraulic liquid, reliably twirl the valve of pumping and establish on it a cap. Double-check the level of hydraulic liquid. |
