Replacing the Articulated Joint on the Short-Stroke Cylinder [03000518-xx]
Parts, equipment and tools
▪ Articulated joint on the short-stroke cylinder [03000518-xx]
▪ 2x ISO4762-M5x35-12.9, geomet. 321+VL [03057290-xx] (screws for movable blade)
▪ Torque wrench 2.5 - 25 Nm [00376625-xx]
▪ Loctite 241 [02101037-xx]
▪ Klüber BEM 34-132 lubricant grease, 1 kg tin [00374565-xx]
Removing the articulated joint
► Remove the cutter from the machine (see "3.9.1 Re-
placing the Cutter on the COT Insert [03066690-xx]"
[ ➙ 154]).
► Loosen the screws (2) fastening the top cover
plate (3) and then remove the cover plate.
► Loosen the screws (2) fastening the baffle plate (3) to
the back of the cutter and remove the baffle plate.
► Remove the caps over the fastening screws (1) on
the movable blade and loosen the blade.
CAUTION!
Risk of injury!
There is a risk of injuring yourself on the cutting edge of
the blades.
► Loosen the circlip (1).
► Push the piston rod a little into the short-stroke cylin-
der and rotate the articulated joint by 90 degrees.
► Push the bolt (2) out of the articulated joint.
► Unscrew the remaining articulated joint adapter (3)
from the piston (4).
NOTICE!
The adapter is secured with locking varnish (Loctite no.
241). You will need somewhat more strength than usual
to loosen it.

3.9.3 Replacing the Articulated Joint on the Short-Stroke Cylinder [03000518-xx] Cutter
Service Manual SIPLACE SX4/DX4 159
Installation
► Screw the articulated joint to the moveable blades. Tighten the screws to a torque of 6 Ncm.
► Follow the removal instructions in reverse order for further installation. Also observe the following
instructions:

3.10.1 Replacing the COT Insert Assembly [03080552-xx] [ ➙ 170]
► Screw the articulated joint into the short-stroke cylin-
der with a torque of 22 Nm. Make sure that the joint
(1) is horizontal so that it fits into the recess in the
moveable blade. Secure the screw with Loctite 243.
CAUTION!
The articulated joint must be horizontal. If not, the blades
could be distorted, which will then cause the joint to
break.
CAUTION
Installation instructions
► Grease the articulated joints slightly with Klüber.
► Secure with screws with Loctite.
► Insert the new screw caps. Remove the protruding plastic residues with a knife.
► Connect the compressed air hoses to the cylinder in the correct allocation.
► Check the gap between the leading edge of the tape deflector and the "empty-tape baffle,
inside".
NOTICE
If the tapes are not cut correctly.
If the tapes are not cut correctly, even though the switching points have been set properly and
the short-stroke cylinder has been exchanged - complete with the one-way restrictor - the cause
of the problem may be:
► Incorrect compressed air level
► Leaking compressed air connection or Y-socket union

Parts, equipment and tools
▪ Short-stroke cylinder 50x40 ECDQ2B50-0040-CEJ00119 [03038587-xx]
▪ Loctite 241 [02101037-xx]
Removal
► Remove the cutter from the machine (see "3.9.1 Replacing the Cutter on the COT Insert [03066690-
xx]" [ ➙ 154]).
Installation
► Remove the articulated joint (5) (see "3.9.3 Replac-
ing the Articulated Joint on the Short-Stroke Cylinder
[03000518-xx]" [ ➙ 158]).
► Use a permanent marker to mark the exact installa-
tion position of the proximity switch (1) on the short-
stroke cylinder.
► Loosen the screws fastening the two inductive prox-
imity switches (1) to the short-stroke cylinder.
► Remove the compressed air connections (2) on the
short-stroke cylinder. You may want to mark their po-
sitions, to make clear assignment easier later on.
► Remove the two screws (3) holding the short-stroke
cylinder.
► Remove the short-stroke cylinder (4) from the cutter.

► Apply a small amount of Loctite no. 241 to the thread
(2) of the new joint.
► Screw the articulated joint (1) into the short-stroke
cylinder.
► Turn the articulated joint in its installation position (3).
Once the cylinder is installed, the slot in the moveable
blade prevents the articulated joint from turning.
► Copy the exact installation position of the proximity
switch (4) onto the new short-stroke cylinder (e.g.
with a feeler gauge, fine-tipped marker pen).
