Disconnect the dual element from the spider
and allow it to rest on the drums. Remove the
air connection tubes.
Remove the fasteners and spacers attaching
the element halves together.
Attach an overhead support to the spider side
element and apply enough tension to support
the weight of the element half and one of the
drums.
Remove the through bolts and nuts attaching
the drums to the drum hub. DO NOT REMOVE
THE SHORT SCREWS AND LOCKWASHERS
WHICH HOLD THE FEMALE DRUM ONTO
THE DRUM HUB. Carefully hoist the spider-
side element and drum out from between the
shafts.
Attach an overhead support to the remaining
element and apply enough tension to support
the weight of the element and drum.
Remove the short screws and lockwashers
holding the drum onto the drum hub and
carefully hoist the element and drum out from
between the shafts.
A
! Caution:
Use extreme care when disconnecting
the drums from the drum hub. Shear
points exist at the mounting holes.

Disassembly of the Element
Lay
the element flat on a clean work surface.
Remove the side plate and clean for reassemb-
ly. If the torque bar holes are elongated more
than one-half the diameter of the pin on the
end of the torque bar, the side plate must be
replaced.
Remove the friction shoe assemblies, torque
bars and release springs. If the torque bars
and springs come out of the element with the
friction shoe assemblies, carefully tap them
out of the backing plate cavities. Note wear
and replace as necessary.
A
! Caution:
Whenever the element is removed
and disassembled, it is always good
practice to replace the release
springs.
Remove the air connection elbows and spiral
snap rings which secure the air actuating tube
to the rim. Smaller size elements do not use
snap rings. Carefully remove the air actuating
tube from the rim and thoroughly inspect.
Replace if necessary.
Note: The snap rings may no longer be re-
quired on certain size elements. Also, rims
manufactured before
1984
were counterbored
at the tube valve hole to accept the snap ring.
This counterbore has been eliminated, and a
second snap ring groove has been added to
the tube valve. See Figure
13.
Remove the remaining side plate only if it is to
be replaced.

Snap Ring Groove Added
