"Gazelle" Gas-2705>> Brake system>> Maintenance service and repair of brake systems>> Repair of a regulator of pressure
Removal from the car of a regulator of pressure and its repair are carried out in the event that adjustment it is impossible to achieve its correct work.
For regulator removal it is necessary:
- To disconnect the bottom end of a rack 24 (fig. 8.4 see) from an arm of the back bridge («Adjustment of a regulator of pressure» see);
- To disconnect pipelines and to muffle their caps of valves of prorolling;
- To disconnect a regulator from an arm 8, having turned on two nuts with spring washers.
Dismantling of a regulator of pressure - is necessary for making in a following order:
- To turn out a bolt 3, to take out a persistent pin 2 and to release the end of a loading spring 12. To take out an axis 4 and to remove press the lever 1, without breaking at dismantling of position of an adjusting bolt 11;
- To remove a protective cover 22,
- To turn out the plug of 20 fastenings of the case of a regulator;
- To take out a returnable spring 19 and a spring washer, and then for a shaft to take the piston 21 with a sleeve 14 and to take out a spring 13;
- To remove from a sleeve a clamping spring 16 and to take out a ball 17 of a sleeve nest;
- To remove a lock washer of an operating cone 15, a flat and spring washer and then an operating cone.
The piston should be taken out from a sleeve when it is necessary for replacement of faulty details.
After dismantling of a detail of a regulator it is necessary to wash out in spirit or a pure brake liquid, attentively to examine, replace defective details, plentifully to grease with a fresh brake liquid and to collect in return sequence.
Insufficient tightness of the ball valve can be a possible cause of defect of a regulator. In that case easy blows of a hammer through copper or aluminium оправку follows подчеканить deepening in a sleeve of a regulator a ball.
Working capacity of a regulator after assemblage should be checked up at the special stand with manometres on an input and an exit of a regulator and the device creating pressure.
Pressure of a liquid upon an exit from a pressure regulator should be approximately in 2,8 times below pressure upon an input. At check, without dumping the specified pressure of a liquid, smoothly to press a loading spring 12 for effort creation on the piston 21. Thus pressure upon an exit should increase that specifies in correct work of a regulator. At creation of certain effort pressure upon an input and an exit should be balanced.
The checked up regulator to establish on the car and to spend drive adjustment. After regulator installation to pump over system and to make check on road («Adjustment of a regulator of pressure» see).
