The service opening pressure of the in-
jectors is 22,0 - 0,8 MPa. The opening
pressure of injectors should be set up to
the upper limit of the range (22,0 MPa)
with spacing washers (1) of different
thickness, which should be put under the
spring (2). The Correct position of the
injection nozzle (3) is determined with
the positioning pins at the sealing sur-
face. The tightening torque of the fixing
nut (4) is 50 to 60 Nm. Before tightening
the nut, push the nozzle against the
spring with leaning it against the wooden
