7.1.6. Adjustment of position of the regulator of pressure


Fig. 7-4. Scheme of installation of the regulator of pressure of back brakes and its adjustment: 1, 2 — bolts of fastening of the regulator of pressure to an arm; 3 — a protective cap; 4 — the torsion lever of the drive of the regulator; 5 — an arm of fastening of the lever to a body; 6 — the piston; 7 — draft of connection with an arm of a beam of the back bridge; 8 — an axis; 9 — the pipeline union for a supply of brake fluid from the main cylinder; 10 — the pipeline union for removal of brake fluid in wheel cylinders; Х = 140 ± 5 mm

If the bolts fixing the regulator of pressure of back brakes weakened it is necessary to adjust its situation. For this purpose weaken bolts of 1 and 2 (fig. 7-4) so that the regulator could be turned easily concerning a fastening arm.

Fig. 7-5. Installation of adaptation 67. 7820. 9518 for adjustment of the regulator of pressure of back brakes: 1 — pressure regulator drive lever arm; 2 — the lever of the drive of the regulator of pressure of back brakes; 3 — adaptation 67.7820.9518; 4 — draft of connection of the lever of the drive of the regulator of pressure with an arm of a beam of the back bridge

Disconnect the lever 4 from draft 7 and fix adaptation 67.7820.9518 (fig. 7-5) on its end. Send a core of adaptation up, against the stop to a body. Most the distance of 140±5 mm between the end of the lever 4 (see fig. 7-4) and a body longeron is established by this.
Raise a protective cap 3 and, turning pressure regulator on bolts, achieve easy contact of the lever with the piston 6. Holding the regulator in this situation, tighten to the full bolts 1 and 2, then cover with a DT-1 lubricant layer axis 8 and the acting part of the piston. Establish into place a rubber cap.
Remove adaptation 67.7820.9518 and connect the end of the lever to draft 7.
