friction lining out to the ends. The rivets are
installed by driving the pin flush with the head.

Assembly of the Element
4.7.1
Make sure all 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
corresponding 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 opposite 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
connections 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.

SPARE PARTS STORAGE
5.1
Element Assemblies
5.1.1
Element assemblies must always be stored flat.
Storage in the standing position may cause the rims
to go out-of-round.
5.2
Drums
5.2.1
Drums must be stored open end down. Similar to
element assemblies, storage of a drum in the
standing position will adversely affect roundness.
5.3
Air Actuating Tubes
5.3.1
Air actuating tubes are shipped from the Airflex
plant folded to conserve shipping space. Upon
receipt, remove the tube from its crate and allow it
to assume its natural shape. Store in a cool, dry
area, away from electrical equipment and ultraviolet
light.
