- The main spindle (6401) is released from the cylinder (1408). The spindle will come out with
the two dowel pins (1403).
- The cap (1413) must now be unscrewed. The spring (1404) and the piston
(1414) can then be removed.
- The seal (0009) can now be changed with a new one.
When mounting the dowel pins, it is recommended that these should be well lubricated so that
they may function correctly.
D.- Fitting/Adapter Maintenance
The adapter seals may possibly suffer due to the high pressure they endure at work. The following steps
should be taken for disassembly;
- Remove the safety ring (1454), take off the copper seal (1455), and take out the square fitting.
- Remove the o-rings and the support rings.
- Replace damaged parts and reassemble.
-Once the spindle has been assembled, the fitting/adapter can be installed. This is done by
threading it into position with a clockwise movement. A hydraulic adhesive is recommended.
