Afterwards, clean the outside of the tappet sealing.
Keep using the fluidic brush, especially for the
outer edge.
Then clean the inner rim of the tappet sealing with
a cleaning rod.
Clean the outside of the tappet centering piece
first with a lint-free cloth.
Use a fluidic brush for the bore of the tappet
centering piece.
Important note!
There is no tappet centering piece, if you use a 2G
tappet rod.
Step 6 (valve body)
Clean the valve with a lint-free cloth.
Step 7 (O-ring)
Clean all O-rings with a lint-free cloth.
Tab. 30: Clean all components by hand
– Dry all the components in the air or with compressed air. For nozzle inserts we recommend to
use the MDT 324 Nozzle Insert Cleaning Holder.
INFORMATION
A two finger seesaw test is necessary to check if the tappet rod runs smoothly through the tappet
centering screw. Otherwise, the parts have to be cleaned again.
In case you still have parts which are not completely clean after the fine purification, repeat the
corresponding cleaning steps for those components several times, if necessary. If that is still not
helping, contact our Technical Support.

9.4.5 Assembling of the Fluid Box and the Tappet
Re-assemble the valve and its components as follows.
Unusual (connector BY)
In the exceptional case that you removed the
connector BY as well, you have to mount it first.
Place the fluid box body on the receptacle of the
mounting body. Align the bore on the fluid box
body with the bore on the mounting body (see
circles). The fluid box body will fit into the mounting
body, if the mounting direction is correct.
Push the Connector BY through the mounting body
into the bore of the fluid box body. Screw the
Connector BY tight (clockwise) by using an MDT 327
(for newer revisions of the Connector BY you can
also use a hexagon key 2.5 or the Torque Wrench
Tool VM with the Bit Hexagon Key 2.5). Torques are
depending on the material of the mounting body
(stainless steel 90 – 100 cN.m, PEEK 70 – 80 cN.m).
Important Note!
Do not press the fluid box body while fastening the
Connector BY, otherwise, it cannot correctly grip
into the fluid box body.
Step 1 (O-ring)
In case that you removed the O-ring, you have to
mount it onto the fluid box body.
Pull the O-ring over the fluid box body with a pair of
tweezers. Be careful not to damage the O-ring.
Step 2 (tappet sealing)
Use the MDT 328 - Tappet Sealing Changing Tool to
press the Tappet Sealing PE/PTFE/HT into the fluid
box body until it sits tight. When the tappet sealing
sits tight, you will hear a light noise.
Step 3 (tappet centering piece)
Press the tappet centering piece into the fluid box.
Use the MDT 328 to make sure the tappet centering
piece rests flat on the tappet sealing.
Important note!
When using a 2G tappet rod, do not use a tappet
centering piece.

Step 4 (tappet and tappet centering screw)
Screw the Tappet Centering Screw BY into the fluid
box. Do not screw it tight yet. Screw it only for two
rotations.
Important note!
Before mounting, please place a small droplet of
Tappet Grease TF (Order no. 1014637; droplet size
ca. 2 mm) on the tappet and another on the tappet
spring (for placing see blue arrows in the picture).
Make sure that the tappet tip is free of grease.
Rotate the tappet and pull it in and out for three
times to spread the grease.
Place the tappet spring over the Tappet Centering
Screw BY.
Push the tappet rod through the tappet spring into
the Tappet Centering Screw BY. Make sure the
tappet goes through the tappet sealing.
Screw the Tappet Centering Screw BY completely
into the fluid box (torque 100 – 140 cN.m) with MDT
303 - Nozzle Insert Changing Tool.
Make sure the three pins of the MDT 303 fit exactly
into the three holes of the Tappet Centering Screw
BY. Turn the MDT 303 clockwise while pressing it
down slightly to the fluid box.
Combine the MDT 303 with MDT 327 for a better
leverage.
Step 5 (nozzle insert)
Clip the nozzle insert into the fluid box. Use the
small hole of MDT 327 to press the nozzle insert.
Make sure the nozzle insert sits flat.
Step 6 (nozzle fixation nut)
Screw the nozzle fixation nut clockwise onto the
fluid box. Use the MDT 327 - Multi-Function Tool
(torque 150 – 180 cN.m).
Step 7 (cartridge base)
Place the cartridge base onto the fluid box and fix it
with the tightening screw. Screw the tightening
screw clockwise with MDT 327 Multi-Function Tool
(torque 120 – 140 cN.m).
