Intermediate plates are located between the
metering device sections. They connect the
mating boreholes within the sections while
also sealing the system against outside in-
fluences. Different plates belong to the inlet,
metering device, and end section.

IMPORTANT
Absolute cleanliness is required when
changing one or more metering device
sections!
The metering device must be cleaned
thoroughly prior to the retrofitting proce-
dure, and the workspace must be free of
contaminants and dust.
The metering device has already been
disassembled, inlet and outlet lines and
mounting screws must already be
removed.
• Clean any contamination from metering
device, place on a clean installation sur-
face or clamp into a vice in a stress-free
position.
• Loosen and remove both self-locking
nuts (1) from the tie-rods (2).
If the tie-rod (2) comes out too when
unscrewing the self-locking nuts (1),
first remove the self-locking nut from
the tie-rod. The tie-rod’s thread must
not be damaged in the process. In place
of the self-locking nut, install two nuts
and position them against each other.
Apply locking adhesive at the other end
of the tie-rod and then use the locknuts
to screw the tie-rid into the inlet sec-
tion (3) with a torque of 2.5 Nm. Then
remove the locknuts.
• Carefully loosen the end section (4) with
end plate (5) from the metering device
sections (6) and and
intermediate plates (7) and remove them
from the tie-rods (2).
While performing the following installa-
tion of the new metering device sections
(6) and intermediate plates (7), be sure
that they are mounted in the correct
position (see Fig. 17, assembly knobs).
• Carefully insert new metering device sec-
tions (6) with new intermediate plates (7)
into the tie-rods.
• Carefully insert the end plate (5) with end
section (4) into the tie-rods and align the
inlet section, metering sections, interme-
diate plate, and end plate as well as the
end section to one another.
