Remove the segment using the segment changing device.
PLEASE NOTE:
If you are removing several segments, note the order of the segments and from which star position you
removed the segments. In this way, you will ensure that the configuration will be correct when you refit the
segments.
●
Place the segments in the segment case.
9.15.4 Removing the nozzle
●
Turn the cam shaft so that the sealing piston is fully retracted.
The slot in the cam shaft must be horizontal.
●
Remove the nozzle.
9.15.5 Dismantling the sealing piston
●
Pull the cam shaft out approximately 3 mm until the sealing piston can be pulled out of the sleeve.
9.15.6 Dismantling the sleeve
●
Place the segment on a clean surface.
●
Take the screwdriver for the sleeve from the sleeve changing tool (see Fig. 9.15.2) and introduce it into the
hole in the sleeve from the nozzle side.
Ensure that the parallel pin of the screwdriver engages in the groove in the nozzle seat.
●
Place the torque insert for the ring nuts (see Fig. 9.15.2) on the ring nut.
●
Use the screwdriver to prevent the sleeve turning when you unscrew the ring nut.
●
Pull the sleeve out of the segment. Be careful not to lose the spring washer, the spacer ring and the upper
deep-groove ball bearing.

Watch the scale disk during assembly. Do not impose any stresses on the scale disk since it could break.
Make sure that the scale disk is not contaminated with oil or grease, which could cause counting errors
and thus placement errors.
●
Insert the friction wheel.
●
Push the sleeve into the segment body as far as the stop.
●
Insert the spacer ring, the spring washer and the upper deep-groove ball bearing.
●
Place the ring nut on the sleeve thread.
●
Check that the torque wrench is set to 20 Ncm.
●
Tighten the ring nut with a torque of 20 Ncm.
●
Turn the sleeve to check the braking effect of the brake.
●
Finally, check that the sleeve can be turned easily when the brake is released.

9.15.11 Checking the segment before insertion
Check the following points before inserting the segment in the star (see Fig. 9.15.3):
–
Is the sealing piston fully retracted? (A)
–
Is the slot in the cam shaft horizontal? (B)
–
Is the cam shaft engaged in the spring plunger? (B)
–
Is the scale disk free from oil and grease? (C)
Wipe away any dust with a clean, dry cloth. (D)
–
Is the scale disk undamaged? (C)
–
Is the circumference of the friction wheel free from oil and grease residues? (D)
Clean the surface with ethyl alcohol, if necessary.
–
Is the sealing slide bush free from contamination? (E)
If necessary, clean it with a pipe-cleaner. To do this, moisten the pipe-cleaner with the cleaning agent on
the segment cleaning cloth and afterwards wipe the sealing slide bush with a dry cloth.
