10.2.6. Removal, service and installation of the executive cylinder of the drive of switching off of coupling

Hit of brake fluid on the painted body surfaces is accompanied by risk of damage of a paint and varnish covering, - incidentally got splashes should be deleted immediately with dry rags or pure paper towels!

Removal

Details of installation of the executive cylinder of the drive of switching off of coupling

1 — the Clamp
2 — the Connecting tube

3 — the Executive cylinder
4 — the Flexible hose


 PERFORMANCE ORDER

  1. By means of a cap key with a cutting head release a nut of fastening of a connecting tube to a flexible hose of a hydraulic path of the drive of switching off of coupling, - hold a reciprocal part of the nipple socket with Rozhkov a key. At once to a zakuporta the open ends of lines in avoidance hit to the highway of dirt.

Try not to overwind a flexible hose.

  1. Turn out fixing bolts and remove the executive cylinder.

Service

In a case disassemble the cylinder, - removal of components is made as their numbering.

Order of dismantling of the executive cylinder of the drive of switching off of coupling

1 — the Flexible hose
2 — the Boot
3 — the Pusher
4 — Assembly of the piston with a cup

5 — the Returnable spring
6 — the Protective cap
7 — the pumping Gate
8 — the Steel ball
9 — the Case of the executive cylinder


 PERFORMANCE ORDER

  1. Spread out the removed components on a pure surface and wash out them brake fluid.
  2. Estimate degree of wear of the piston, a cup and a mirror of the cylinder whether check the returnable spring weakened. Replace defective components.
  3. Assembly is made upside-down, edges of the piston and a cup before gas station in the cylinder should be greased with pure brake fluid. Track that the nipple socket of a flexible hose was tightened with the required effort (16 ÷ 23 Nanometers).

Installation

 PERFORMANCE ORDER

  1. Installation is made as it should be, the return to an order of dismantle of components, - track observance of requirements of Specifications of the Head the Transmission line to efforts of tightening of carving fixture, for tightening of a nipple nut use a cap key with a cutting head (do not forget to fill a clamp between a basic arm and a nipple nut of a connecting tube). Do not forget to pump over a hydraulic path.

The nipple nut has to get correctly to hexagonal deepening of a flute. Try not to allow twistings of a flexible hose also.

Pumping of a hydraulic path

 PERFORMANCE ORDER

  1. Removal from a hydraulic path of the drive of switching off of coupling of air traffic jams is made via the pumping gate on a body of the executive cylinder.
  1. Check liquid level in the GTTs tank, - during pumping the tank has to remain filled at least on 3/4.
  2. Remove a protective cap and pull a piece of a vinyl hose of the suitable size on the pumping gate. Lower the second end of a hose in the transparent capacity which is partially filled with brake fluid.
  3. Ask the assistant to squeeze out several times slowly a coupling pedal, then to record it in the lower situation.
  4. By means of a cap key with a cutting head weaken the gate of pumping and produce hydraulic liquid in a reception container.
  5. Tighten the gate and repeat the procedure, - pumping should be continued until liquid, pure, free from air bubbles, does not begin to follow from the cylinder.

During the procedure watch that liquid level in the GTTs tank did not fall more than on 1/4, - non-performance given the requirement is accompanied by risk of a podsasyvaniye of air to hydraulic highways of drives of brake mechanisms and coupling with need of performance of full pumping both!

  1. In conclusion tighten the pumping gate with the required effort (58 ÷ 7.5 Nanometers) and make sure of serviceability of functioning of coupling.
