8.3. Removal and installation of the main cylinder of coupling

Hydraulic liquid is poisonous. It also well dissolves paint. Be careful, do not allow liquid hit on open sites of a body or in eyes. Hold near at hand rags for collecting the poured liquid, and in case of hit it on the painted surfaces immediately wash away liquid plentiful amount of cold water.

Removal

 PERFORMANCE ORDER

  1. Uncover the tank with brake liquid (for models with left foreign management) or the tank with hydraulic liquid of coupling (for models with right-hand management) and by means of a syringe remove liquid from the tank. On models with left foreign management level of liquid should be lower than connection of the brake line with the main cylinder.
  2. On models with right-hand management disconnect a hydraulic hose from the lower part of the tank and merge the remained liquid.
  3. Give a connecting nut and disconnect the union of the hydraulic line of coupling from a forward part of the main cylinder.
  1. Working under the dashboard, remove the bottom panel of a covering from the driver (see. Head Body). Give a bolt of fastening of a pusher of the main cylinder of coupling to a coupling pedal.
  1. Give two bolts of fastening of the main cylinder to an arm of a pedal of coupling, disconnect a hydraulic hose from the top part of the main cylinder and remove the main cylinder. Keep in readiness rags for collecting the poured liquid.

Installation

 PERFORMANCE ORDER

  1. Installation generally repeats removal procedure upside-down. Where it is provided, track, that the nadtsentrovy spring of a helper correctly rose in the directing. Do not forget to tighten fixing bolts of the main cylinder with demanded effort. Reliably tighten a connecting nut of the hydraulic line of coupling.
  2. Check adjustment of a pedal of coupling (see. Section Adjustment of a pedal of coupling). Where it is provided, also check adjustment of the switch of coupling (see. The section Check of work and replacement of the switch of coupling (where it is provided)).
  3. Fill the tank with fresh hydraulic liquid and pump over coupling system (see. Section Pumping of hydraulic system of coupling).
