Service of the main cylinder

Removal and installation


Location of the main cylinder of coupling on models of 4.2 l


  1. Cover with protective covers the right forward mudguard.
  2. Disconnect a hydraulic tube from the main cylinder. Zakuporte the end of a tube and an opening in the cylinder in order to avoid hit in hydraulic system of dirt and for the purpose of minimization of losses of liquid.
  3. On models of 3.0 l disconnect a pusher of the main cylinder from a coupling pedal.
  4. Give fixing nuts and remove the main cylinder from the car. Try not to allow hits of hydraulic liquid on the painted body surfaces.

At hit of hydraulic liquid on a paint and varnish covering immediately wash away it a plentiful amount of water, then allow a surface to dry in the natural way, - do not wipe it with rags.


Installation is made upside-down.


  1. Tighten fixing nuts with the required effort.
  2. Pump over hydraulic system.



  1. After removal of the main cylinder remove hydraulic liquid from its tank.
  2. Weaken a collar and separate the tank from the main cylinder.
  3. Separate a rubber cover from the end of the main cylinder.
  4. Remove a lock ring from the end of the cylinder, then (according to a complete set) remove a pusher, a washer and a rubber cover.
  5. Take from the cylinder assembly of the piston with a spring (see an accompanying illustration - components of the main cylinder of models of 4.2 l are shown).
1 — a cover
2 — the tank
3 — a collar
4 — nuts
5 — the cylinder
6 — the piston
7 — a washer
8 — a lock ring

Cleaning and check of a state


  1. Wash out all components of the main cylinder methyl alcohol.

Do not apply gasoline or mineral alcohols to this purpose at all.

  1. Check a cylinder mirror for existence of signs of wear and traces of corrosion, in case of need make replacement.

Honingovaniye of the main cylinder of coupling it is inadmissible. At identification of major defects of a mirror it is necessary to replace the cylinder assembled.

  1. Check piston assembly for existence of signs of wear, scratches, zadir and traces of corrosion. Pay special attention to a condition of cuffs of the piston. In case of need make replacement.
  2. At the corresponding complete set check a pusher and a washer for existence of signs of wear and damages. Replace defective components.
  3. Check the tank of hydraulic liquid for existence of cracks and other damages. In case of need make replacement.
  4. Check serviceability of a condition of a collar of fastening of the tank. In case of need replace.


There where it is possible, surely use the special remnabor including new cuffs and the piston in the structure. Use of such company sets will allow to prolong block service life substantially.


  1. Grease with special lubricant (for rubber components) a piston cuff, a mirror of the cylinder and, at the corresponding complete set, a rubber cover.
  2. Install assembly of the piston with a spring in the cylinder. On models of 4.2 l establish a washer and a new lock ring.
  3. On models of 3.0 l check existence on a pusher of a rubber cover, then establish and fix by a new lock ring a pusher with a washer. Pull a protective cover on the cylinder case.
  4. Install the tank on the main cylinder and reliably fix it by a collar.
  5. Fill in fresh hydraulic liquid in the tank, then shake the piston manually before emergence of liquid in an opening under installation of a hydraulic tube on the cylinder case.
  6. Install the main cylinder on the car.
