Caution! Collect and dispose of leaking fuel.
It is prohibited to remove and install the pressure regulator without using a tool.
The pressure regulator is installed (is used) just once.
The pressure regulator on the hydraulic accumulator must be replaced in the following order. For details, see Fig. 6.109 and 6.119. Read the information in the fault memory of the "DDE" system.
Remove the air intake manifold, close the intake ports and disconnect the shock absorber (1, Fig. 6.116) from the pressure sensor. When removing the pressure sensor, hold it from turning by the hexagon (2). Unscrew the hexagonal threaded fastener (3) on the hydraulic accumulator and pull the pressure regulator (3) out of the hydraulic accumulator.
The pressure regulator should be installed in the reverse order, while it is necessary to fix the regulator in the required position and hold it from turning by the hexagon (2). Preliminarily fix the sensor in the required position and tighten the hexagonal threaded fastening (3) with a torque of 70 N·m (7.0 kgf·m). Assemble the engine and check the operation of the "DDE".
