The Nexen DPC Clutch has been balanced
at the factory. During disassembly, mark
components with chalk alignment marks to
insure correct alignment and balance as the DPC Clutch
is reassembled (See Figure 6).
When reassembling the Nexen DPC Clutch, make sure all
screws are tightened to the recommended torque (See
Table 4 in OPERATIONS SECTION).
CAUTION
Working with spring loaded or tension
loaded fasteners and devices can cause
injury. Wear safety glasses and take the
appropriate safety precautions.

worn Friction Facings (Item 4).

compound. If remove is difficult, strike the end
of the screwdriver with a hammer to break the

before attempting to remove the screws. The
Machine Screws (Item 11) that are furnished
