8. Disassembly and Assembly Instructions

The system joint is delivered fully assembled. All functions are checked beforehand.
You have to disassemble the system joint for mounting it in the orthosis and for main-
tenance. To ensure an optimal functioning, follow the assembly instructions below. Se-
cure all screws with the torque specified in paragraph 8.8. The assembly is illustrated
with the NEURO VARIO-SWING system ankle joint as an example.

8.1 Demounting the Cover Plate

1 Unscrew both countersunk flat head screws.
2 Place the washer on the cover plate and screw the pressing screw into the thread
of the first screw (S1). The pressing screw must not be screwed in completely
(fig. 5).
3 Push the joint's upper part and the cover plate apart by exerting force on them as
illustrated (arrows in fig. 5). This can be achieved by using a vice or by controlled
knocks.
4 Remove pressing screw and washer.

8.2 Mounting the Cover Plate

Make sure not to damage the sliding washer during the assembly. Jammed
sliding washer particles can cause lateral play in the system joint.
1 Clean the bearing nut, the thread of the joint's upper part and the bores of the
cover plate with LOCTITE® 7063 Super Clean, if necessary.
2 Apply spray adhesive on one side of a sliding washer and adhere it to the cover
plate (fig. 6).
3 Grease the other side slightly with orthosis joint grease.
4 Mount the cover plate by pressing it with the pressing screw and the washer
(fig. 7).
5 Remove pressing screw and washer.
6 Screw in the first countersunk flat head screw (S1; fig. 8).
7 Make sure that there is no opening left between the cover plate and the joint's
upper part (fig. 9).
