Removal

PERFORMANCE ORDER
1. To disconnect a wire from "the minus" plug of the storage battery.
2. To disconnect from the main cylinder a tube of a supply of a working liquid and to muffle a tube aperture.
3. To remove the bottom facing of the panel of devices at the left for access reception to fastening of the main cylinder.
4. To disconnect from an end face of the main cylinder a tube, having turned away a fastening nut, and to muffle a tube aperture.
5. To disconnect a plug of a pusher from a coupling pedal, having removed a lock ring and having taken out a finger.
6. To turn away two bolts of fastening and to remove the main cylinder from the car.

Dismantling

PERFORMANCE ORDER
1. To clear the main cylinder of a dirt.
2. To remove грязезащитный a cover from the case of the main cylinder.
3. To remove a lock ring and to take out a pusher from the case.
4. To push out through a face aperture by means of approaching прутка from the case of the cylinder the piston before its occurrence from the cylinder. Definitively to take out the piston from the cylinder case together with a returnable spring.
5. To remove a spring from the piston and a cuff.

Survey and дефектовка details of the main cylinder

PERFORMANCE ORDER
1. To wash out details of the main cylinder a pure brake liquid and to dry.
2. The mirror of the main cylinder should not have рисок, bowls and the corrosion centres. In the presence of the given defects it is necessary to replace the cylinder. On carving parts of the cylinder there should not be mechanical damages.
3. Cuffs of the main cylinder should be elastic and elastic. The fragmentary, inflated and hardened cuffs, and also risks having on working surfaces, it is necessary to replace.
4. The end of a pusher and an interfaced surface of the piston should not have obviously expressed traces of unilateral deterioration. The surfaces of the piston contacting to a mirror of the cylinder, also should not have traces of unilateral deterioration. Otherwise it is recommended to replace a pusher and the piston. The piston valve should not have visible traces of deformation and should adjoin densely to a piston end face.
5. The grjazezashchitnyj cover of the main cylinder should not have cracks and through apertures. It should be established on a pusher and the case of the main cylinder with a small tightness. Otherwise a cover to replace.
6. The spring should possess elastic properties. Spring breakage is not supposed.
7. The carving of tips of a tube and a hose should not have mechanical damages. The union of tips should not have cracks and traces of visible deformation.

Assemblage

PERFORMANCE ORDER
1. To grease a cuff with a pure brake liquid and to establish it on a spring, сориентировав a working edge to a spring.
2. To insert accurately spring into the cylinder case.
3. To grease a cuff with a pure brake liquid and to establish it on the piston, сориентировав a working edge to a spring.
4. To insert the piston with put on on it перепускным a ring into the cylinder case.
5. To establish lock скобу on a pusher if it removed.
6. To insert a pusher into the case of the cylinder and to establish a lock ring.
7. To establish грязезащитный a cover on the cylinder case.

Installation

PERFORMANCE ORDER
To establish the main cylinder of a drive of coupling upside-down. Thus bolts of fastening of the main cylinder to tighten the moment 20 Н·м (2,0 кгс·м). After installation to pump over a coupling hydrodrive (subsection 7.3.4 see).

Adjustment of a free wheeling of a pedal of coupling

PERFORMANCE ORDER
1. To weaken an inhaling of a counternut of a plug of a pusher.
2. Unscrewing or twisting a pusher a hand or by means of flat-nose pliers, to achieve excess of position of a pedal of coupling concerning a brake pedal on 10 mm.
3. To tighten a counternut.
