10.3 Conversion of NEURO CLASSIC
As a supporting joint, the NEURO CLASSIC system ankle joint can be converted into the main joint if the
system stirrup from the main joint has been used.
1 Demount the cover plate of the NEURO CLASSIC system joint.
2 To convert into system ankle joints with feather keys, press the feather
keys with pin into the joint's upper part by using the outer assembly/
lamination dummy. Additionally, you need a longer bearing nut. To
do so, use the bearing nut, the feather keys with pin and the outer
assembly/lamination dummy from the respective set for converting to
plug + go modularity.
3 Mount the functional unit or the cover plate of the main joint in the
correct system width (fig. 21).
11. Maintenance
Check the system joint for wear and functionality every 6 months. Also check the functionality after every
maintenance carried out.
