5.1 Lubrication
Apply 633F16=0.250 Lubricant to all moving metal surfaces (except the 4B74 Brake
Bushing) in the modular knee joint.
5.2 Replacing the Brake Bushing
If the brake bushing must be replaced, proceed as follows:
Unhook the Extension Assist Cable (20) (fig. 2). Remove the Axis Screw (17) from the joint
section using a 6 mm hex head wrench (fig. 6). Push the guide surface of the knee axis out of
the lower joint section to the rear and up (fig. 7). Remove the Brass Washers (18). Turn the
stance control adjustment screw clockwise to open the axis hole (fig. 8). Push out the knee
axis and remove the brake bushing.
Before installing the new brake bushing, be sure the Bushing Safety Device (16) is seated
properly (fig. 9). Install the new brake bushing (fig. 10). Sparingly apply 633G6 Lubricant to
the knee axis and press into the bushing.
Reassemble in the reverse order.
Tighten the Axis Screw (17) using a torque wrench 710D4.
Torque: 25 Nm/18.4 ft.lbf./221 lbf.in.
Adjust joint functions as described under section 4.
Attention
To eliminate noise in the cosmetic foam cover, use 519L5 Silicone Spray. Do not use
talcum powder! Talcum powder reduces the lubrication of the mechanical parts, which
may lead to a malfunction and thus increase the risk of falling. Using this medical product
after application of talcum powder will render all claims against Otto Bock Orthopedic
Industry null and void.
Apply 519L5 Silicone Spray directly on the friction surfaces of the cosmetic foam cover!
