17.20. Repair of the main brake cylinder

To disassemble

Dismantle of consolidation of the main brake cylinder

AND. SCREW-DRIVER

9. CONSOLIDATION

Shift of pistons in the main cylinder

AND. WOODEN OR PLASTIC PUSHER
CENTURY OF 3-MM ELECTRODE WIRE

5. CASE OF THE MAIN CYLINDER

Dismantle of a lock ring

AND. SCREW-DRIVER
CENTURY OF 3-MM WELDING WIRE

8. LOCK RING

Dismantle of the back piston from the main cylinder

AND. THE HOSE TIP WITH THE COMPRESSED AIR

6. BACK PISTON ASSEMBLED

PERFORMANCE ORDER
1. To dismantle the main cylinder assembled.
2. To clamp the main cylinder in a vice and to dismantle a tank 2.
3. To take out consolidation 9 of a cylinder opening.
4. To move pistons 6 and 7 in the cylinder approximately on 10 mm, using a wooden or plastic pusher of the suitable size. To fix pistons in the shifted situation, to insert into a compensatory opening of the cylinder of 3-mm an electrode wire (see fig. Shift of pistons in the main cylinder).
5. By means of a screw-driver to take out a lock ring 8 of a cylinder flute.
Prevention

To protect pistons and internal walls of the main cylinder from mechanical damages.

It is forbidden to use a lock ring repeatedly.


6. To move pistons 6 and 7 in the cylinder, using a wooden or plastic pusher of the suitable size, and to take out a wire.
7. To take out the forward piston 7 of a cylinder opening. For this purpose it is necessary to knock with a cylinder end face on a wooden lining.
8. To take out the back piston 6 of a cylinder opening.
9. A cable from the butterfly valve case. For this purpose it is necessary to use the compressed air.
10. To wash up all details fresh brake liquid or alcohol. To dry up details a stream of the compressed air.
11. To examine an internal surface of the cylinder on existence of scratches and corrosion traces. In the presence of defects to replace the main brake cylinder.
Prevention

It is forbidden to use the abrasive tool, a skin and the means containing abrasive particles, for processing of an opening of the main cylinder.

It is forbidden to use repeatedly rubber consolidations and a lock ring 8.



To collect

PERFORMANCE ORDER
1. To grease an internal surface of the main cylinder with fresh brake liquid.
2. To clamp the case 5 of the main cylinder in a vice so that connecting openings for a tank settled down from above.
3. Carefully to insert into a cylinder opening the back piston 6 in collecting and to advance it against the stop in the cylinder. For advance of the piston to use a wooden or plastic pusher.
4. To insert the forward piston 7.
5. To wring out pistons 7 and 6 in the cylinder and to insert into a compensatory opening of the cylinder a welding wire for fixing of pistons in the course of installation of a lock ring 8.
6. To insert a new lock ring 8 into a flute in a cylinder opening.
Prevention

To operate carefully, not to damage an internal surface of the main cylinder.


7. To wring out pistons 7 and 6 in the cylinder by means of a pusher and to take out from a compensatory opening of the cylinder a welding wire.
8. To check free and smooth moving of pistons in the main cylinder.
9. To grease with fresh brake liquid consolidation 9 and to insert it against the stop into a lock ring in a cylinder opening. Consolidation 9 should be turned by an open cavity outside.
10. To establish into place the main brake cylinder assembled.
11. To remove air from a hydraulic actuator.
