5. Repairs
The components of VOSS
quick connect system 232 do
not wear or tear as a result of
operation.
Should any of the compo-
nents be damaged as a result
of inappropriate handling,
these may be replaced as
required.
5.1 Replacing the thread-
sealing o-ring
The old o-ring can be re-
moved when the system is
disconnected from the com-
ponent (see section 4.5).
Clean the groove in the cou-
pling element carefully and
check that it is not damaged.
The coupling element must be
replaced if there are any signs
of damage (see section 5.2).
Then replace the old o-ring
with a new one which has
been greased. All damage,
excess stretching or twisting
of the o-ring is to be avoided
when fitting.
5.2 Disconnecting coupling
element
Break the connection (see
section 4.5) and lever off the
fixing ring using a suitable tool
(see fig. 1). Take care that the
plug is not damaged in this
process.
Then pull the clips sideways
out of the retaining ring. This
can be done by inserting a
pointed tool through the slot
in the cage behind the clips
(see fig. 2).
Once the two clips and the
retaining ring have been
removed, the plug may be
pulled out of the male nut.
A suitable disassembly tool is
available on request.
1. Slide disassembly
tool onto fixing ring
3. Insert disassembly
hook from below
and pull out first clip
sideways
To reassemble, always use a
new coupling element when-
ever the plug has been
removed from the male nut. In
addition, the o-rings for the
plug must be checked,
replaced if necessary and re-
greased.
5.3 Replacing plug o-rings
The damaged o-ring can be
removed after disconnection
(see section 5.2). Clean the
groove carefully, and then
replace the old o-ring with a
new one which has been
greased. All damage, excess
stretching or twisting of the o-
ring is to be avoided when
refitting. This applies both to
the sealing o-ring and to the
dirt-protection and pretension
o-ring.
5.4 Lubrication of the
o-rings
In order to ensure the functio-
nal reliability of the o-rings,
use only grease that has
been tested and approved by
VOSS.
Approved lubricating greases
are:
- Bechen – Berulub
Hydrohaf 2
- Bechen – Berulub
Hydrohaf GR
- Klüber – SYNTHESO
