7.8.1. Removal and installation


Fig. 7-19. Pressure regulator drive details: 1 — pressure regulator; 2 — pressure regulator drive lever axis; 3 — an antisplash cap; 4 — a lock plate; 5 — a bolt with a spring washer; 6 — the back bridge; 7 — draft of connection of the lever of the drive of the regulator of pressure with an arm of a beam of the back bridge; 8 — a bolt nut; 9 — the plastic plug; 10 — the expansion plug; 11 — a draft fastening bolt; 12 — pressure regulator drive lever; 13 — a nut for fastening of a bracket to a body; 14 — a spring washer; 15 — a flat washer; 16 — a bracket of fastening of the lever of the drive of the regulator of pressure; 17 — the rubber plug

Disconnect the lever 12 (fig. 7-19) from draft 7, and then a bracket 16 from a body and the bracket of fastening of the pipeline going to pressure regulator.
Disconnect from a body of a detail of a suspension bracket of mufflers and take the pipeline with mufflers aside.
Turn off bolts of fastening of the regulator to an arm and an arm to a body.
Remove a regulator arm, and then, having lowered the regulator down, disconnect from it pipelines.
Remove the regulator and disconnect from it the drive lever. Muffle entrance and exhaust outlets of the regulator of pressure and pipelines.

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


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

You carry out installation of the regulator of pressure to the sequences, the return to removal. Before tightening of bolts of fastening of the regulator install on the end of the lever of the drive of the regulator adaptation 67.7820.9518 (see fig. 7-5). Send a core of adaptation up to an emphasis to a body. Most the distance of 140±5 mm is established by this (see. "Adjustment of position of the regulator of pressure") between the end of the lever 4 (see fig. 7-4) and a body longeron.
Raise a protective cap 3 (see fig. 7-4) and, turning the regulator on fastening bolts, achieve that the end of the lever appeared in easy contact with the regulator piston.
Holding the regulator in this situation, tighten to the full bolts of its fastening, then cover with a DT-1 lubricant layer axis 8 and the acting part of the piston. Establish into place a rubber cap 3.
Remove adaptation 67.7820.9518 and connect the end of the lever to draft 7, previously having greased with DT-1 lubricant of the plug of hinged connection of draft with the lever.
Attach pipelines of system of production of gases to a body.
Pump over brakes for removal of air from the drive of back brakes.
