Air removal from a hydraulic path of a drive of switching off of coupling

Used as a working body in a path of a drive of coupling hydraulic liquid is among toxic and chemically aggressive connections and at contact to body panels destroys a paint and varnish covering. Before starting performance of procedure cover wings and the panel of a front of the car with special covers, or simply old blankets. Pumping of brake system make in goggles. At casual hit of brake liquid in eyes immediately wash out them a plentiful quantity of water and address for the help to the doctor!

Pumping of a hydraulic drive of switching off of system should be carried out each time after removal of its components and also when liquid level in the tank falls so that air gets to the main cylinder. A pumping principle the same, as used at air removal from a brake path. When pumping use only fresh hydraulic liquid of a demanded grade.

 PERFORMANCE ORDER

  1. The gate of pumping is located in a place of fastening of a hydraulic hose from above on RKPP case. On some models access to the gate can be complicated. To Poddomkratta the car also establish it on props.
  2. Make sure of tightness of shtutserny connections of a hydraulic path of coupling. Carefully wipe the pumping gate.
  3. Uncover the tank of the main cylinder and fill in in the tank fresh hydraulic liquid, having finished its level to a mark the MOVE. Establish a cover into place. Remember that during system pumping in order to avoid risk of a podsasyvaniye liquid level in the tank should not fall to the air highway below MIN mark.

Do not use liquid repeatedly extorted from system, and also, liquid, a long time stored in leaky closed container!

The main method of pumping - is required the help of the assistant

 PERFORMANCE ORDER

  1. Remove a dustproof cap and pull on the gate of pumping of the cylinder the end of a plastic hose suitable on the size. The second end of a hose lower in transparent vessel partially filled with hydraulic liquid, - track, that the cut of a hose appeared entirely is shipped in liquid.
  1. Ask the assistant to press several times a pedal of coupling with the purpose of lifting of pressure in a path, then to squeeze out it and to fix it in the bottom situation. Open the gate of pumping and let out liquid from the cylinder in drain capacity. When the effluence of the liquid mixed with air bubbles will stop, again densely tighten the gate and allow to release to the assistant a pedal.
  2. Continue pumping in the same manner until liquid leaving the cylinder completely will not be released from air bubbles. Constantly watch closely liquid level in the tank of the main cylinder, without allowing its excessive lowering, air dangerous by hit to the highway and data to zero of all undertaken efforts.

Pumping method with set use with the return valve

As tells the name, the piece of a hose equipped with the one-pass valve enters into a set for pumping. The valve prevents possibility of return of pushed-out liquid back in system and will allow to make pumping by strengths of one person, - do not forget about need of tracking of level of liquid for the tank of the main cylinder (it should not fall below MIN mark!).

Pumping with use of the compressed air

 PERFORMANCE ORDER

  1. As a source of the compressed air the spare wheel can be used, - previously it is necessary to dump pressure of its rating. Act according to instructions enclosed to a set.
  2. When using the similar device it is required to release only the gate of pumping and to wait the exit terminations from a path of air bubbles.
  3. The main advantage of this way is that the big tank entering into a set with hydraulic liquid is not allowed by an air podsasyvaniya to the highway during pumping.

All methods

 PERFORMANCE ORDER

  1. Having finished pumping, check a course of a pedal of coupling, - if taking place softness is completely eliminated, tighten the pumping gate with demanded effort, plant on it a protective cap and collect rags traces of the spilled liquid.
  2. Check liquid level in the tank of the main cylinder, - in case of need make the corresponding adjustment (see. Head Routine maintenance).
  3. The merged liquid is not subject to a reuse should be utilized according to requirements for environmental protection.
  4. Check serviceability of functioning of coupling, - if its switching off when squeezing a pedal does not occur, therefore, not all air is removed from a path and pumping is necessary for repeating. If to achieve satisfactory result it is not possible during several pumpings, it is necessary to check a condition of sealing elements of shtutserny sockets of hydraulic lines on both cylinders.
