Installing tool 67.7820.9518 for adjusting the rear brake pressure regulator
1 - arm of the pressure regulator drive lever; 2 – the lever of a drive of a regulator of pressure of back brakes; 3 - fixture 67.7820.9518; 4 – thrust connecting the pressure regulator drive lever with the bracket of the rear axle beam
1. If the bolts securing the pressure regulator are loose, it is necessary to adjust its position. To do this, loosen bolts 1 and 2 (see fig. Installation diagram of the rear brake pressure regulator and its adjustment) so that the regulator can be easily rotated relative to the mounting bracket.
2. Disconnect lever 4 from rod 7 and fasten tool 67.7820.9518 at its end (see fig. Installation of tool 67. 7820. 9518 for adjusting the rear brake pressure regulator).
3. Point the tool rod up until it stops in the body. This sets the distance x 140±5 mm between the end of the lever 4 (see fig. Installation diagram of the rear brake pressure regulator and its adjustment) and body spar.
4. Raise the protective rubber cap 3 and, turning the pressure regulator on the bolts, achieve a light contact of the lever with the piston 6 (see fig. Installation diagram of the rear brake pressure regulator and its adjustment).
5. Holding the regulator in this position, tighten bolts 1 and 2 to failure, then coat axle 8 and the protruding part of the piston with a layer of grease DT-1 (see fig. Installation diagram of the rear brake pressure regulator and its adjustment). Place 5-6 g of the same lubricant in the rubber cap and replace it.
6. Remove the fixture and connect the end of the lever with the rod 7 (see fig. Installation diagram of the rear brake pressure regulator and its adjustment).
