Torque Limiting Coupling
4.6
Assembly of the element
4.6.1
Make sure all of the components have been cleaned
and any damaged or worn components have been
repaired or replaced.
4.6.2
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.
4.6.3
Lay the rim/side plate assembly on a clean, flat work
surface, side plate down.
4.6.4
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). See Figure 11.
4.6.5
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
(51TLC1600, 60TLC1600, 66TLC1600 and
76TLC1600 elements have two release springs in
each cavity) (the 76TLC2000 has only one release
spring per shoe) into place. Make sure the spring(s) 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 11.
4.6.6
Lay the remaining side plate in position so
the air connections and torque bar holes are
properly aligned.
4.6.7
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.
4.6.8
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.
4.6.9
Note the orientation of the air connections and install
the through bolts and locknuts where applicable.
4.6.10 Re-install the elbows using a good quality sealant on
the pipe threads. Install the air connections on the
element. Install the short air connections.
4.6.11 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 container and allow
it to assume its natural shape. Store tube(s) in a cool,
dry area, away from electrical equipment and
ultraviolet light.
