Mounting the Cover Plate

Make sure not to damage the sliding washer during the assem-
bly. Jammed sliding washer particles can cause lateral play in
the system joint.
1 Clean the threads of the cover plate with LOCTITE® 7063 Super Clean,
if necessary.
2 Apply spray adhesive on one side of the first sliding washer and
adhere it to the cover plate (fig. 20).
3 Grease the other side slightly with orthosis joint grease.
4 For system joints with flexion stop disc/step lock stop disc: Press it
against the joint's lower part (fig. 21).
5 Grease the axle bore of the joint axis and the friction surfaces of the
bearing nut of the joint axis with orthosis joint grease.
6 Put the bearing nut of the joint axis into the opening of the joint's
upper part (fig. 22).
7 Grease the second sliding washer slightly on both sides with orthosis
joint grease.
8 Place the sliding washer onto the joint's upper part (fig. 23).
9 Mount the joint's lower part (fig. 24). For a simplified mounting to the NEURO LOCK
system knee joint, make sure that the joint is flexed.
Some NEURO LOCK cover plates do not have a hollow for the sliding washer due
to manufacturing reasons. Position the second sliding washer in such a way that
the bore for the bearing nut is not covered.
10 Place the cover plate onto the system joint.
11 Screw in the first countersunk flat head screw (axle screw, S1;
fig. 25).
12 Screw in the second countersunk flat head screw (S2; fig. 26).

Checking the Joint's Free Movement

Check if the system joint moves freely. If the system joint runs with
lateral play, mount the next thicker sliding washer. If it does not move
freely (it is jammed), mount the next thinner sliding washer.
