4.6.3 Attach the new lining to the backing plate with new
screws and locknuts or drive pin rivets
(See Figure 15), as applicable. Work from the center
of the friction lining out to the ends. The rivets are
installed by driving the pin flush with the head.

4.7 Assembly of the Element
4.7.1 Make sure all of the components have been cleaned
and any damaged or worn components have been
repaired or replaced.
4.7.2 Assemble one of the side plates to the rim with cap
screws and lockwashers. It is not necessary to install
through bolts and locknuts at this time.
4.7.3 Lay the rim/side plate assembly on a clean, flat work
surface, side plate down.
4.7.4 Carefully insert the air actuating tube into the rim.
Push the valves on the tube through the correspond-
ing holes in the rim and install the spiral snap rings (if
applicable).
4.7.5 Place a torque bar in each mating hole in the side
plate, slide a friction shoe assembly onto each torque
bar and carefully tap a release spring (51VC1600,
60VC1600 and 76VC1600 elements have two release
springs in each cavity) into place. Make sure the
spring is positioned on the side of the torque bar oppo-
site the friction lining. Also, the spring must contact the
torque bar at two points, not one. See Figure 16.

4.7.6 Lay the remaining side plate in position so the air con-
nections and torque bar. Holes are properly aligned.
4.7.7 Carefully guide the torque bars into the corresponding
holes in the side plate. It is often helpful to install four
equally spaced screws and nuts through the rim and
side plate to keep some tension on the side plate
throughout this step.
4.7.8 Attach the side plate to the rim with cap screws and
lockwashers, making sure all of the torque bars are
seated in their side plate holes.
4.7.9 Note the orientation of the air connections and install
the through bolts and locknuts where applicable.
4.7.10 Re-install the elbows (or quick release valves), using a
good quality sealant on the pipe threads. Install the air
connections on single narrow, dual narrow and single
wide elements. Install only the short air connections
(element closest to spider) on dual wide elements.
4.7.11 Re-install per 2.0.
