Adjusting the position of the pressure regulator (VAZ-2121)

If the bolts securing the pressure regulator have loosened, adjust its position by first raising the rear axle of the vehicle. Then disconnect lever 4 (Fig. 6-6) from rod 8 and attach device 67.7820.9519 to its end. Direct the rod of the device upwards until it stops at the body floor (Fig. 6-7). This sets the distance "X" from the end of the lever to the body side member (see fig. 6-6), equal to 150±5 mm.







Lift the protective rubber cap 6 (Fig. 6-6) and, by turning the pressure regulator on the bolts, achieve light contact of the lever with piston 2.

Holding the regulator in this position, tighten bolts 1 and 7 until they stop, then coat axle 5 and the protruding part of piston 2 with a thin layer of DT-1 grease. Place 5-6 g of the same grease in rubber cap 6 and install it in place.

Remove tool 67.7820.9519 and connect the end of the lever to rod 8.
