Dual assemblies use the same values as listed above.
For element to element fasteners, use element to spider fastener sizes and torque value.

Mounting Considerations
2.2.1
The element must be protected from
contamination by oil, grease or excessive
amounts of dust.
Oil or grease contamination will re-
sult in a reduction of developed
clutch or brake torque. Either of
these conditions will result in clutch
or brake slippage and overheating.
All rotating equipment must be
guarded to comply with applicable
safety standards.
2.2.2
For clutch and brake applications, shaft align-
ment must be within the tolerances indicated
in the Alignment section of this manual.
Operation with shaft misalignment
exceeding the limits indicated in the
Alignment section of this manual will
result in accelerated wear of the ele-
ment components. Severe mislign-
ment will result in excessive
vibration and/or overheating when
disengaged due to dragging of the
friction shoes.
2.2.3
All mounting fasteners must be of the proper
size and grade, and torqued to the appropri-
ate value. See Table 1.
